Question

What is the size of port numbers in tcp requests given that there can be 65536 (2^16) ports in total

Answer 1

Answer:

65535

Explanation:

• The size of port numbers in tcp requests given that there can be 65536 (2¹⁶) ports in total is almost 16 bits. As mentioned, the dynamic range commences till 65536 thus valid ports are 2¹⁶-1 or 65535 (16 bits each).

• There are ports segregated into well known ports that are from 0 to 1023, registered ports that ranges from 1024 to 49151 and dynamic ports also called as private ports that ranges from 49152 to 65532 and are of 16 bits each.
