Gateway Internet Address :
Adress of the gateway to which traffic for the network specified in the internet destination network field of the originaldatagram's data should be sent.
****************************************
Identifier : Nếu code = 0, một identifier to aid in matching echos and replies,
may be zero.
+Sequence Number :
If code = 0, a sequence number to aid in matching echos and
replies, may be zero.

******************************************
Redirect Message sent to the transmitting host by an intermediate router telling it about a more eddicient path to receiver. ICMP can automatically add paths to an IP host ‘s route table even if link-state routing is not enabled on the host.
