Primary TCP/IP Port Assignments and Descriptions
| Port | Assigment | Description |
|---|---|---|
| - The File Transfer protocol provides a mechanism for transferring specific files between network connected computer systems (usually a Linux or UNIX based system). Transfer is typically performed using the client which provides a range of commands used to connect to a remote server for the purpose of uploading or downloading files. Most modern web browsers also have the ability to browse and download files located on a remote FTP server. FTP uses TCP (rather than UDP) to transfer files so is considered to be a highly reliable transport mechanism. FTP does not encrypt data and is not considered to be a secure file transfer protocol. The use of Secure Copy Protocol ( ) and Secure File Transfer Protocol ( ) is strongly recommended in place of FTP. | ||
| - Traditionally FTP has two ports assigned (port 20 and port 21). Port 20 was originally conisidered the data transfer port, while port 21 was assigned to communicate control information. In modern implementations port 20 is now rarely used, with all communication taking place on port 21. | ||
| - The Secure Shell is used to provide a secure, encypted, remote logon session to a remote host over a TCP/IP network. The original mechanism for remote access was the Telnet protocol. Because Telnet transmits data in plain text its use is now strongly discouraged in favor of the secure shell, which encrypts all communications, including log-in and password credentials. SSH also provides the mechanism by which files can be securely trandferred using the Secure Copy Protocol ( ), and is also the basis for the Secure File Transfer Protocol ( ). SSH also replaces both the and clients. | ||
| - Telnet is a terminal emulation protocol that provides the ability to log into a remote system over a TCP/IP connection. The access is text based allowing the user to type into a command prompt on the remote host and text displayed by the remote host is displayed on the local Telnet client. Telnet encrypts neither the password nor the text communicated between the client and server. As such, the use of telnet is strongly discouragaed. Most modern systems will have port 23 closed and the telnet service disabled to prevent its use. SSH should be used in place of Telnet. | ||
| - SMTP defines the mechanism by which email messages are sent from one network host to another. SMTP is a very simple protocol and requires that the mail service always be available at the receiving host. Typically the receiving host will store incoming messages in a spool for subsequent access by the recipient using the POP3 or IMAP protocols. SMTP uses the TCP transport protocol to ensure error free message delivery. | ||
| - The service used by TCP/IP networks to translate host names and Fully Qualified Domain Names (FQDN) to IP addresses. | ||
| - TFTP is a strpped down version of the File Transfer Protocol (FTP). It has a reduced command-set and lacks authentication. The most significant feature of TFTP is that it uses UDP to transfer data. This results in extremely fast transfer speeds but, consequently, lacks data reliability. TFTP is typically used in network based booting for diskless workstations. | ||
| - HTTP is the protocol used to download text, graphics and multimedia from a web server and to a web browser. Essentially it defines the command and control mechanism between the browser and server defining client requests and server responses. HTTP is based on the TCP transport protocol and, as such, is a connection-oriented protocol. | ||
| - The POP3 protocol is a mechanism for storage and retrieval of incoming email messages from a server. In most corporate environments incoming email is stored on an email server and then downloaded to an email client running on the user's desktop or laptop when the user checks email. POP3 downloads all new messages to the client, and does not provide the user the option of choosing which messages to download, view headers, or download only parts of messages. It is for this reason the IMAP protocol is increasingly being used in place of POP3. | ||
| - The protocol responsible for posting and retrieving messages to and from Usenet News Servers (i.e newsgroups and discussion forums hosted on remote servers). NNTP operates at the Application layer of the OSI stack and uses TCP to ensure error free message retrieval and transmission. | ||
| - A protocol designed to synchronize computer clocks with an external time source. Using this protocol an operating system or application can request the current time from a remote NTP server. The remote NTP server is usually based on the time provided by a nuclear clock. NTP is useful for ensuring that all systems in a network are set to the same, accurate time of day. This is of particular importance in security situations when, for example, the time a file was accessed or modified on a client or server is in question. | ||
| - IMAP4 is an advanced and secure email retrieval protocol. IMAP is similar to POP3 in that it provides a mechanism for users to access email messages stored on an email server, although IMAP includes many additional features such as the ability to selectively download messages, view message headers, search messages and download part of a message. IMAP4 uses authentication and fully supports Kerberos authentication. | ||
| - Provides a mechanism whereby network administrators are able to collect information about the devices (such as hubs, bridges, routers and switches) on a network. The SNMP protocol enables running on network devices to communicate their status to a central and, in turn, enables the to send new configuration parameters to the device . The can further be configured to notify the when certains events, known as , occur. SNMP uses UDP to send and receive data. | ||
| - The standard HTTP (non-secure) protocol transfers data in clear text (i.e with no encryption and visible to anyone who might intercept the traffic). Whilst this is acceptable for most web browsing purposes it poses a serious security risk when confidential information such as credit card details need to be transmitted from the browser to the web server. HTTPS addresses this by using the Secure Sockets Layer (SSL) to send encypted data between the client and server. | ||
| - Originally developed by Sun Microsystems and subsequently widely adopted throughout the industry, NFS allows a file system on a remote system to be accessed over the network by another system as if the file system were on a local disk drive. NFS is widely used on UNIX and LINUX based systems. Later versions of Microsoft Windows possess the ability to also access NFS shared file systems on UNIX and LINUX based systems. |

TCP IP Ports
A comprehensive guide to tcp/ip ports: understanding tcp port numbers and their significance.
In the realm of computer networking, TCP/IP ports play a pivotal role in facilitating communication between devices over the internet. Understanding TCP port numbers and their significance is crucial for network administrators, developers, and enthusiasts alike. This comprehensive guide sheds light on TCP ports, their numbering system, common usage, and much more.
TCP (Transmission Control Protocol) ports serve as virtual endpoints for communication sessions between devices connected to a TCP/IP network. Each TCP port is assigned a unique number ranging from 0 to 65535. These ports are categorized into three ranges: well-known ports (0-1023), registered ports (1024-49151), and dynamic or private ports (49152-65535).
TCP Port Number List:
Below is a list of commonly used TCP port numbers along with their respective services:
Port 80: HTTP (Hypertext Transfer Protocol)
Port 443: HTTPS (HTTP Secure)
Port 22: SSH (Secure Shell)
Port 21: FTP (File Transfer Protocol)
Port 25: SMTP (Simple Mail Transfer Protocol)
Port 3389: RDP (Remote Desktop Protocol)
Port 3306: MySQL Database Server
Port 8080: HTTP Alternate (commonly used for proxy and caching servers)
Registered Ports:
Registered ports (1024-49151) are assigned by the Internet Assigned Numbers Authority (IANA) to specific services or applications. These ports are typically used by well-known software and protocols, such as database systems, email servers, and network services.
TCP Port Range:
The TCP port range encompasses numbers from 0 to 65535, offering a vast array of communication channels for various applications and services. Understanding how to configure and manage port ranges is essential for optimizing network traffic and security.
How to Access TCP Ports:
To access a TCP port, you can utilize network tools such as Telnet or netcat. By specifying the IP address and port number, you can establish a connection to the desired service or application running on a remote device. Additionally, developers often interact with TCP ports programmatically using socket programming libraries in languages like Python or Java.
Exploring TCP Port 443:
TCP port 443 holds significant importance as it is commonly associated with HTTPS (HTTP Secure), the encrypted version of HTTP. Port 443 is utilized for secure communication over the internet, ensuring the confidentiality and integrity of data exchanged between clients and servers. It is widely used for secure online transactions, login pages, and sensitive information exchange.
TCP/IP ports form the backbone of internet communication, facilitating the seamless exchange of data between devices. By understanding TCP port numbers, ranges, and their applications, network professionals can effectively manage network traffic, enhance security, and optimize service delivery.

Nathan, thank you for supplying this sheet. It comes in handy when you’re trying to remember what a particular port is used by.
Our pleasure.
Thank you, Nathan
This is a great single point to reference all default ports. Thank you!!!
Very good, it will be in front of me!
Ports on computers are required for networking, and without them, the computer would be completely isolated and it would be unable to communicate with other devices. So thank you for proving this list of the Common TCP and UDP Port numbers.
After resetting my router cause the password got changed and all the setting were changed to gain access to my computer. I spent about 20 minutes setting up the router. It appears the router never got set up from the cable company when it was installed. So if you have not done so lately check your router and settings.
Cool, Thanks for sharing!!
Sorry Nathan, i did not leave a comment for this “Common Ports” Chart last-week. I am glad i signed up to your news letter you are a good researcher. thank you for sharing with us all..
Nathan, I must thank you for these cheat sheets! They’ve been great on my learning and certification journey!
Thank you too!
Really really useful.Thanks a lot!!

How Does Internet Work
Tcp and udp port numbers – complete list.
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.
Let’s see who makes it possible? The Internet Assigned Numbers Authority (IANA) assigns all port numbers except Dynamic or Private ports. IANA is a standards organization in the world that is responsible for assigning various addressing standards.
There are different types of port numbers: Well Known Ports (Numbers 0 to 1023), Registered Ports (Numbers 1024 to 49151) and Dynamic or Private Ports (Numbers 49152 to 65535). The last porn number type Dynamic or Private Ports will not appear on our list because they are cannot be registered with IANA. This range is used for custom or temporary purposes and for automatic allocation of ephemeral ports. They are usually assigned dynamically to client applications when initiating a connection. It is not very common for a client to connect to a service using a Dynamic or Private Port, sometimes some peer-to-peer file sharing programs do.
We will introduce the list of the ports with short description of different port types.
Using both TCP and UDP is also normal sometime. Some applications may use both TCP and UDP. For example, the low overhead of UDP with his short header enables DNS to serve many client requests very quickly. However, sending the requested information sometimes may require the reliability of TCP. In that case, the port number of 53 that is a well known port number is used by both protocols with this service.
Let’s see the list of port numbers:
- Well-known ports
- Registered Ports
Well Known Ports (Numbers 0 to 1023) – These numbers are reserved for services and applications. They are commonly used for applications such as HTTP (web server) POP3/SMTP (e-mail server) and Telnet. By defining these well-known ports for server applications, client applications can be programmed to request a connection to that specific port and its associated service.

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.

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 register with IAMA to be used for a particular service. These should be treated as semi-reserved.
- Port 49152 to 65535: These are port numbers used by client programs, such as a web browser. When you visit a web site, your web browser will assign that session a port number from within this range. As an application developer, you are free to use any of these ports.

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.
Service names and port numbers are used to distinguish between different services that run over transport protocols such as TCP, UDP, DCCP, and SCTP. Service names are assigned on a first-come, first-served process, as documented in [ RFC6335 ].
Primary TCP/IP Port Assignments and Descriptions. TCP/IP provides a total of 65,535 ports of which 1023 are considered to be well known ports. In reality the number of ports that are used by popular network clients and services comprises an even smaller subset of the well known group of ports.
Each TCP port is assigned a unique number ranging from 0 to 65535. These ports are categorized into three ranges: well-known ports (0-1023), registered ports (1024-49151), and dynamic or private ports (49152-65535).
Some of these ports are only authorized for one of the two protocols (TCP or UDP). There are also ports that were not officially registered for the service in question, but have established themselves unofficially. Some ports have double assignments.
110. SHARES. Perhaps you’re angsty that you’ve forgotten what a certain port number meant. Rest assured, you don’t have to remember all 65,535 port numbers. With so much information to remember, it’s understandable if you forget a common port. That’s why we put together this cheat sheet of common network ports for you.
Valter Popeskic Protocols, Transport layer 1 Comment. 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. Let’s see who makes it possible?
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 numbers range from 0 to 65535, but only port numbers 0 to 1023 are reserved for privileged services and designated as well-known ports. The following list of well-known port numbers specifies the port used by the server process as its contact port.
This topic lists the well-known port assignments for transport protocols TCP and UDP, and includes port number, keyword, and a description of the reserved port assignment. You can also find a list of these well-known port numbers in the hlq .ETC.SERVICES data set.
