Question: Compare the header fields in the IPv4 and IPv6 protocols. Explain some strategies for converting IPv4 packets to IPv6 packets in a hybrid IP network. If you were in charge of a large 1000+ node that was required to support IPv6 within a short timeframe (say 1 year), what strategy would work best? If there was a longer timeframe to migrate (say 3 years), would it make sense to choose a different strategy? Why or why not?
