ICMP Message Control
ICMP stands for Internet Control Message Protocol. When it is impossible to transmit data
or configure route for data, ICMP sends error message about it to host. The first 4 bytes
of all ICMP messages are same, but the other parts are different according to type field
value and code field value. There are fifteen values of field to distinguish each different
ICMP message, and code field value helps to distinguish each type in detail.
The following table shows explanation for fifteen values of ICMP message type.
