Port numbers are 16-bit unsigned integers, which range from 0 to 65535 in size. TCP uses port number 0, while UDP uses port number 0, and a value of zero means no port is available.

What Are The Three Ranges Of Port Numbers?

  • There are a number of well-known ports. These ports are between 0 and 1,023 in number.
  • There are 1,024 – 49,151 registered ports.
  • There are 49,152 – 65,535 dynamic and/or private ports.
  • What Is Valid Range Of Port Number?

    Port values (PORT) Valid values range from 1 to 65535. TCP/IP applications, however, use some of the ports in the range 1 through 1023. These ports can affect the operation of applications if the user specifies one of them.

Port facilities can be temporary or private. In addition to being private, they are also known as non-reserved ports or non-reserved ports.

    Is 65535 A Valid Port?

    TCP port 65,535 is the highest port number. In TCP, 16 bits are provided for port numbers, and this is interpreted as an unsigned integer; all values are valid, apart from 0, and so the largest port number is (2*16 – 1) or 65,535.

    How Do I Check If A Port Number Is Valid?
