Question

What is Port number for TCP,UDP,IGMP,ICMP ?

this might be silly question but still wants some little discussion.

Answer 1

Port number is assigned by Transport Layer, so applications which uses services of transport layer will get port numbers.

example : HTTP is application layer protocol and it uses transport layer (TCP protocol ) with port number 80.

ICMP and IGMP are network layer protocols so they does not having PORT No.
