These TCP and USP ports are also asked in many network engineering technical interviews as interview questions. Some of these well-known ports are used by TCP and some of them are used UDP. And the full list of these port numbers are in RFC 1700. These port numbers are given by IANA (Internet Assigned Numbers Authority). Well-known network ports are from 0 to 1024. You can download the Cheat Sheet about Well-known network ports. Beside SCTP (Stream Control Transmission Protocol) and DCCP (Datagram Congestion Control Protocol) use these ports. Only one port is required for full-duplex, bidirectional traffic. TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) uses these well-known ports. These ports in networking are not registered with IANA. Daynamic ports are the ports from 49152 to 65565.

The last part of ports in networking are dynamic ports. These portsa re assigned by IANA for specific services.

The other network ports are registered ports between 101. IANA (Internet Assigned Numbers Authority) assigns these well-known ports. The full list of these network port numbers are given in RFC 1700. These well-known ports are the reserved ports between.

Some of these port numbers are well-known ports. These network port types are given below: There are three different port types used networking. The range of these network ports are from 0 to 65535. In computer networking, there are network port numbers used for various applications.
