Ono je to takto explicitne napsano jiz RFC792 (ICMP):
Code
0 = net unreachable;
1 = host unreachable;
2 = protocol unreachable;
3 = port unreachable;
4 = fragmentation needed and DF set;
5 = source route failed.
[...]
Codes 0, 1, 4, and 5 may be received from a gateway. Codes 2 and
3 may be received from a host.
