Icmp port. ICMP sits at the network layer (Layer 3 in the OSI model), alongside IP, instead of above it. The Internet Control Message Protocol (ICMP) is a network layer protocol used by network devices to communicate. The ICMP (Internet Control Message Protocol) is a protocol used by devices to diagnose network communication problems. The Internet Control Message Protocol (ICMP) is a protocol that devices within a network used to communicate problems with data transmission. But ICMP does more than help The Internet Control Message Protocol (ICMP) has many messages that are identified by a "type" field. Het ICMP Type bepaalt het soort bericht.
