Problem
1. What is the purpose of including the IP header and the first 8 bytes of datagram data in the error reporting ICMP messages?
2. What is the maximum value of the pointer field in a parameter-problem message?
3. Give an example of a situation in which a host would never receive a redirection message.
4. Make a table showing which ICMP messages are sent by routers, which are sent by the non-destination hosts, and which are sent by the destination hosts.
