How an ICMP message is transported?
ICMP messages are transmitted as datagrams and consist of an IP header that encapsulates the ICMP data. A datagram, much like a packet, is a self-contained independent entity of data.
How do I send a ping message?
You may specify up to 16 ”pad” bytes to fill out the packet you send. This is useful for diagnosing data-dependent problems in a network. For example, -p ff will cause the sent packet to be filled with all ones. E.g. ping -p 486920686572652e www.example.com , where 486920686572652e = Hi here.
