Registered Ports >> Registered Ports
Registered Ports (Numbers 1024 to 49151) – These port numbers are assigned to user processes or applications. These processes are primarily individual applications that a user has chosen to install rather than common applications that would receive a Well Known Port. When not used for a server resource, these ports may also be used dynamically selected by a client as its source port.

This is very helpful. Thank you for the information! You may want to change a word in the sentence (The last porn number type Dynamic or Private Ports.).

Port number is a 16-bit numerical value that ranges from 0 to 65535. Well-known port (0-1023), registered port (1024-49151), and dynamic port is three types of port number space. (49152-65535).
These ports can be opened and used by software applications and operating system services to send and receive data over networks (LAN or WAN) that employ certain protocols (eg TCP, UDP).
For example, we use 80 for HTTP-web-based plain-text surfing and 443 for HTTPS-web-based encrypted websites in our daily work.
To conclude, a port is a logical form to identify system activities or various network services used to create local or network-based communications.
When interacting over the Internet, TCP and UDP protocols make connections, recompile data packages after the transfer, and then deliver them to applications on the recipient’s device. For this handover to work, the operating system must install and open the gateway for the transfer. Each door has a unique code number. After transmission, the receiving system uses the port number to determine where the data should be sent. The port numbers of the sender and receiver are always included in the data packet.
Ports are assigned sequential numbers from 0 to 65535. Some of these codes are standardized, meaning they are assigned to certain uses. Since code numbers are universally recognized and permanently assigned, these standard ports are also known as well-known ports. Registered ports are those that organizations or software developers have registered for their applications. Registration is handled by the Internet Assigned Numbers Authority (IANA). A diverse selection of dynamically assigned port numbers is also available. For example, when viewing websites, browsers use these ports. After that, the port number is free again.
Any security researcher, bug bounty hunter, or anyone working with service configuration would benefit from this. Knowing how to do more thorough scans such as version detection or known vulnerabilities for ancient services that are still operating in the infrastructure, especially when using tools like Nmap, is handy when getting to know these protocols and services.
The following are some of the most common service names, transport protocol names, and port numbers used to differentiate between specific services that employ TCP, UDP, DCCP, and SCTP.

The physical ports on your computer allow communicate with peripheral devices such as your keyboard and mouse and to connect with internet devices via Ethernet cables.
The Linux Terminal
Witin computer networking, ports serve a similar purpose. When a computer system seeks to connect to another computer, the port serves as a communication endpoint. It is also possible for different services running on the same computer to expose various ports and communicate with one another using these ports. In simple terms, if a software application or service needs to communicate with others, it will expose a port. Ports are identified with positive 16-bit unsigned integers, ranging from 0 to 65535. Other services use this port number to communicate with the service or app. Port numbers are divided into three ranges: well-known ports, registered ports, and dynamic or private ports.
Well-known ports (also known as system ports ) are numbered from 0 through 1023. For example, to connect to the host example.com via SSH, I would use this command:
In this example, -v stands for verbose, and you should see output similar to this:
As shown, SSH is trying to connect to example.com using port number 22. You may use the -p option to specify another port number; otherwise, SSH will default to 22.
The Internet Assigned Numbers Authority (IANA) has assigned port numbers to commonly used services like SSH, FTP, HTTP, HTTPS, and others. Here are some of the most common ones:
Port Number | Usage |
20 | File Transfer Protocol (FTP) Data Transfer |
21 | File Transfer Protocol (FTP) Command Control |
22 | Secure Shell (SSH) |
23 | Telnet - Remote login service, unencrypted text messages |
25 | Simple Mail Transfer Protocol (SMTP) E-mail Routing |
53 | Domain Name System (DNS) service |
80 | Hypertext Transfer Protocol (HTTP) used in World Wide Web |
110 | Post Office Protocol (POP3) used by e-mail clients to retrieve e-mail from a server |
119 | Network News Transfer Protocol (NNTP) |

143 | Internet Message Access Protocol (IMAP) Management of Digital Mail |
161 | Simple Network Management Protocol (SNMP) |

443 | HTTP Secure (HTTPS) HTTP over TLS/SSL |
In my work, I most commonly come across ports 80, 443, 20, 21, 22, 23, 25, and 53. Knowing these ports can help you work more efficiently.

It’s a pain trying to memorize port numbers and their corresponding service names and protocols. So, we created this concise cheat sheet of common network ports and their associated protocols and service names for you to use as a quick reference.
Feel free to print it out and hang it up or share a link to it with your colleagues and peers. Use it to speed up port identification or as a training resource for onboarding new network administrators or engineers.
Click on the network port chart above to view the printable, searchable PDF version. Scroll down below for the port list tables.
This list is by no means exhaustive. It just lists the most frequently used ports. There are a total of 65,535 TCP/UDP ports. They are divided into 3 classes:
IANA (Internet Assigned Numbers Authority), in case you’re wondering, is the organization that oversees global IP address allocation and port classification.
Some common protocols that use these ports:
Well-known network ports range from 0 to 1023. These ports are assigned by IANA and listed in RFC 1700 . On most systems they can only be used by system (or root) processes or by programs executed by privileged users. Some well-known ports use TCP, some use UDP, and some can be configured to use either.
Well-known TCP ports are used by applications that rely on TCP as the transport protocol. Examples:
Well-known UDP ports are used by applications relying on UDP. Examples:
Knowledge of these ports is helpful for network engineers looking for work as they are popular topics asked about in technical interviews.

Dynamic/Private network ports refer to the range of ports from 49152 to 65535 that are not officially registered with IANA for any specific service or application and are available for private or temporary use.
They can be used by applications dynamically as needed, usually for establishing temporary connections. Often they are used by client-side applications that initiate connections to servers on well-known or registered ports.
A common example of dynamic network port use is Ephemeral Ports. These are short-lived transport layer ports used when an application on a client device makes an outgoing connection to a server. They allow a client application to use a random available port for its side of the connection which has multiple benefits from enabling multiple connections from the same client application to traversing firewalls as most firewalls are configured by default to allow connections from ephemeral ports to well-known ports.
The dynamic/private port range also provides ports for private or customized services within an organization since they are unregistered.
Prepping for an exam or interviewing for a role in networking or a networking adjacent field? Prioritize memorizing the ports below.
In my experience, these are the ports most frequently used in certification exams and to quiz candidates in technical interviews.

Numbered 0 Through 1023
The Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) each use port numbers for their communication channels. The ports numbered 0 through 1023 are the well-known system ports , reserved for special uses.
Port 0 is not used for TCP/UDP communication although it used as a network programming construct.

Port numbers are divided into three ranges: well-known ports (0-1023), registered ports (1024-49151), and dynamic or private ports (49152-65535). Well-known ports are reserved for common services and are typically assigned by the Internet Assigned Numbers Authority (IANA). For example, port 80 is reserved for HTTP traffic, while port 22 is used for SSH.
Registered ports are used by specific applications or services and are assigned by IANA upon request. These ports are typically used by proprietary applications or custom services. Dynamic or private ports, on the other hand, are not assigned and can be used by any application or service as needed.
Ports Master provides information about the port numbers in each range, along with their associated services and any relevant notes or considerations.

In computer networking, there are network port numbers used for various applications. The range of these network ports are from 0 to 65535 . There are three different port types used networking. These network port types are given below:
Some of these port numbers are well-known ports. These well-known ports are the reserved ports between 0 and 1023 . The full list of these network port numbers are given in RFC 1700. IANA (Internet Assigned Numbers Authority) assigns these well-known ports.
The other network ports are registered ports between 1024 and 49151 . These ports are assigned by IANA for specific services.
The last part of ports in networking are dynamic ports. Daynamic ports are the ports from 49152 to 65565 . These ports in networking are not registered with IANA.
TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) uses these well-known ports. Only one port is required for full-duplex, bidirectional traffic. Beside SCTP (Stream Control Transmission Protocol) and DCCP (Datagram Congestion Control Protocol) use these ports.
You can download the Cheat Sheet about Well-known network ports.

Well-known network ports are from 0 to 1024 . These port numbers are given by IANA (Internet Assigned Numbers Authority) . And the full list of these port numbers are in RFC 1700.
Some of these well-known ports are used by TCP and some of them are used UDP. These TCP and UDP ports are also asked in many network engineering technical interviews as interview questions . So, what are these ports in networking?
Well-known TCP ports are the network ports used by the applications that works with TCP as transport protocol. So, what are these applications that uses well-known TCP ports ?
For example, FTP (File Transport Protocol) is one of the applications that uses TCP ports. The FTP ports are TCP port 20 and TCP port 21 . The other applcation that uses TCP as transport protocol is Telnet. Telnet uses TCP port 23 .
Well-known UDP ports are the network ports used by the applications that works with UDP as transport protocol. So, what are these applications that uses well-known UDP ports ?
For example TFTP (Trivial File Transport Protocol) is one of the applciations that uses UDP ports. UDP port 69 is used by TFTP. Another example that uses UDP as transport protocol is SNMP. SNMP uses UDP port 161 for SNMP and UDP port 162 for SNMP trap messages.
Below, you can find all the wellknown ports used by the applications that uses TCP & UDP network ports .

I've written a WCF Service hosted by a Windows Service and it needs to listen on a known TCP/IP port. From what range can I safely allocate a port for use within my organization? That port will be embedded in the config files for the service and the clients that are consuming the service.
Ports 0-1023 are the Well Known Ports and are assigned by IANA. These should only be used for the assigned protocols on public networks.
Ports 1024-65535 used to be called Registered Port Numbers (see rfc1700 ) but are now split into two areas (see rfc6335 ).
Ports 1024-49151 are the User Ports and are the ones to use for your own protocols.
Ports 49152-65535 are the Dynamic ports and should not be prescribed to a protocol.
The User Ports can be used for any protocol, but there are a finite number, so your use will clash with someone elses use on some network somewhere. IANA keep a record of registered port numbers (0-49151). If your protocol will be used on public networks then you need to look into registering it with IANA. If you are only using it within your own network then pick a port within this area (1024-49151) and check that port against the IANA register to make sure it isn't used by a protocol that could be used on your network. For private use it is probably better to pick a number that is assigned to a protocol you know won't be used than to choose one that is unassigned and so may be assigned in the future.
Don't use a port number within the Dynamic range. These ports are assigned by the operating system, dynamically and somewhat randomly. If you open a client connection (using bind() with port=0) you will be assigned an unused port from the dynamic range. There is no way to guarantee that a port in this range will always be free for your protocol.
Pick a port number from 49152 through 65535.
IANA publishes a list of currently assigned ports.

The Dynamic and/or Private Ports are those from 49152 through 65535. This is the range from where you SHOULD pick a port for your in-house applications. Of course any port belonging to one of the unassigned ranges on the published list can be used. But be aware that by picking a port number from those unassigned ranges there is no guarantee whatsoever that the port you choose will not be a reserved port in the future.
UNASSIGNED PORT NUMBERS SHOULD NOT BE USED. THE IANA WILL ASSIGN THE NUMBER FOR THE PORT AFTER YOUR APPLICATION HAS BEEN APPROVED.
And make sure that the port number you pick is configurable as you stated:
That port will be embedded in the config files for the service and the clients that are consuming the service.
This will avoid headaches in case some other 3rd party you-cannot-touch software is using your port number. If that happens you just go ahead and change it on the configuration file and it just works.
Short answer: Avoid anything up to and including 1023, or over 49152, and test the chosen port against services on your network.
If you've taken the reasonable precautions that it appears you have (putting the port number in a config file), it shouldn't be an enormous disruption if you later discover a conflict.
But (so that I can add something to the other suggestions that have popped up while I've been typing) make sure that you make it easy to change! If it's in config files, make it obvious. Document it, and point it out in troubleshooting. It's the sort of thing that could go wrong, so make it easy to debug if it needs changing.
In addition to the other suggestions about picking a common application port, I'd suggest that you make the port configurable within your application. Hard-coded port numbers are a bad idea, particularly if you later find a port conflict with another application and need to change yours.
As a note remember to check those port by netstat /a /n to see if its using by other application or not. I find out vista used the 49152 .... for some application level reason. Basically, because most of the system level listener does not implement port sharing its much safe to use the those ports which are not used at all.
Here is a good list of common application ports . Make your own choice in an empty slot. Maybe you should also scan your network for any in-house special application.
Typically high numbers port are available and I would suggest them but they could be blocked by firewalls.

This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for duplex, bidirectional traffic. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.
Use this comprehensive common ports cheat sheet to learn about any port and several common protocols. It also includes a special search and copy function.
SCTP. Service names are assigned on a first-come, first-served process, as. documented in [ RFC6335 ]. Port numbers are assigned in various ways, based on three ranges: System. Ports (0-1023), User Ports (1024-49151), and the Dynamic and/or Private. Ports (49152-65535); the different uses of these ranges are described in.
This is a list of Internet socket port numbers used by application communication with TCP and UDP on the Transport Layer of the Internet Protocol Suite for the host-to-host communications.
50 Common Ports You Should Know. Port number is a 16-bit numerical value that ranges from 0 to 65535. Well-known port (0-1023), registered port (1024-49151), and dynamic port is three types of port number space. (49152-65535). These ports can be opened and used by software applications and operating system services to send and receive data over ...
Learn about the roles and functions of UDP and TCP ports, how they enable communication between applications, and what are the most common and important ports.
Here are some of the most often-encountered network ports and their associated services.
As a server administrator, it's essential to understand the functions of common services and their respective port numbers. Similar to how an IP address determines the computer's identity, the network port is key in identifying the specific application or service operating on that computer.
Port (computer networking) In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service. A port at the ...
It's a pain trying to memorize port numbers and their corresponding service names and protocols. So, we created this concise cheat sheet of common network ports and their associated protocols and service names for you to use as a quick reference.
The Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) each use port numbers for their communication channels. The ports numbered 0 through 1023 are the well-known system ports, reserved for special uses.
Common Port Assignments Table D-1 lists currently assigned Transmission Control Protocol (TCP) port numbers. To the extent possible, the User Datagram Protocol (UDP) uses the same numbers.

Network ports are used in networking for the specific network applications. Well-known ports are used by TCP and UDP Applications.
This document provides recommendations to designers of application. and service protocols on how to use the transport protocol port. number space and when to request a port assignment from IANA. It. provides designer guidance to requesters or users of port numbers on.
About TCP/UDP Ports. Port 0 to 1023: These TCP/UDP port numbers are considered as well-known ports. These ports are assigned to specific server sevice by the Internet Assigned Numbers Authority (IANA). For example, port 80 is used by web servers. Port 1024 to 49151: These are ports that an organization, such as application developers, can ...
Note Service names and port numbers are used to distinguish between different services that run over transport protocols such as TCP, UDP, DCCP, and
