What is the most common IP version presently in use?
What is fragmentation? What fields of the IP header are used for fragmentation?
What is the purpose of the TTL field in the IP header? How does the TTL process work?
What is the first octet rule?
How are Class A, B, and C IP addresses recognized in dotted decimal? How are they recognized in binary?
