Ping (ICMP) is Layer 3 or Layer 4 Protocol?
There is always a debate on is Ping (ICMP) a layer 3 or layer 4 protocol? If it is Layer 4 which protocol it uses TCP or UDP? Ping is very common network utility to test the end to end connectivity between the two end points (can be machines, a router, etc). Ping utility uses ICMP protocol for its functioning. ICMP is a Layer 3 protocol; it does not use any Layer 4 protocol for its functioning. It packs all its ICMP information under IP packet.
