Common network ports, well-known & registered tcp & udp ports

What is computer port?

TCP, Transmission Control Protocol, and UDP, User Datagram Protocol, are both protocols which use IP. Whereas IP makes two computers to communicate with each other across the Internet, TCP and UDP make the individual applications or services on those computers to communicate with to each other.

Since a computer might have multiple applications running on the same IP address, ports allow a computer to tell the differences from services such as email data from web data. A port is just a number assigned to each application to identify that service on that computer. Both TCP and UDP use ports to identify services. Some common port numbers are 80 for web (HTTP), 25 for email (SMTP), and 53 for Dmain Name System (DNS). The following are a list of well-known and registered ports:

Well-known ports: 1-1023

According to IANA "The Well Known Ports are assigned by the IANA and on most systems can only be used by system (or root) processes or by programs executed by privileged users. Ports are used in the TCP [RFC793] to name the ends of logical connections which carry long term conversations. For the purpose of providing services to unknown callers, a service contact port is defined. This list specifies the port used by the server process as its contact port. The contact port is sometimes called the "well-known port"."

1023/TCP,UDP Reserved Official

Registered ports: 1024-49151

Only those ports that are commonly used are listed; for full list, refer to the IANA port list.

When investigating TCP traffic, be careful not to confuse the client and server ports. The client port is incremental, typically beginning at 1024 at boot time and wrapping at 4096. If the port you are investigating is in the lower part of this range, it may be a client port. Stateful firewalls identify the server port, but packet sniffers and stateless firewalls do not. For example, a packet sniffer showing a TCP packet with source port 1080 and destination port 1494 might be either the SOCKetS or Citrix Independent Computing Architecture (ICA) protocols. The only way to know for sure is to examine the initial TCP handshake.

With UDP, client port selection depends on the application and may be incremental, fixed to a nonsensical value, or fixed equal to the server port.
