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 ac-cording 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.
