Question

Discuss whether a socket address is unique in the Internet (i.e., TCP/IP) or not.

Answer 1

Obviously the Socket address in the Internet(TCP/IP) is unique.

the socket address for a particular socket on a particular host is unique Because the internet address will be always unique to a particular host on a network.

Every connection between internet hosts is also uniquely identified.

Actually the Socket address is the combination of an IP address and port number.

TCP/IP will be having a 16-bit port numbers in each host. it is possible for the ports on different hosts to have the same port number. but it creates the socket address as an identifier which will be unique throughout all the internet networks.

therefore , it is not possible to have the same socket address in the internet because the internet address itself will be unique.
