What is 49152 through 65535?

Dynamic ports—Ports in the range 49152 to 65535 are not assigned, controlled, or registered. They are used for temporary or private ports. They are also known as private or non-reserved ports. Clients should choose ephemeral port numbers from this range, but many systems do not.

What is port address 65535?

The highest TCP port number is 65,535. The TCP protocol provides 16 bits for the port number, 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.

Network Ports Explained

Why is 65535 the limit?

65535 is the largest number that can be held in a 16 bit unsigned integer. As this is the size of the port field in TCP/UDP then that limits the range of port numbers.

Why is 65535 important?

In computing

In older computers with processors having a 16-bit address bus (such as the MOS Technology 6502 and the Zilog Z80), 65535 (FFFF₁₆) is the highest addressable memory location, with 0 (0000₁₆) being the lowest. Such processors thus support at most 64 KiB of total byte-addressable memory.
