a. How many possible IP addresses are there in IPv4? (Ignore any reserved or special addresses and give the total possible number.) Does IPv6 give more, less, or the same number of addresses? Briefly explain. b. Consider the network of LANs in the diagram below. Dark squares are routers, and light squares are hosts. Give the IP routing tables at both routers, including netmasks and gateways. c. Give, and explain, the path through the network for a packet originating at 128.100.1 1.2 with destination 128.100.13.1. d. If you send a packet to the IPv4 address 127.0.0.1, where does it go? Briefly explain. 128.100.ILI 128.100.11.2 128.100.11.0 128.100.11.3 128.100.12.I 128.100.12.2 128.100.12.3 128.100.12.0 Internet 128.100.12.254 128.100.13.1 128.100.13.2 128.10.13.3 128.100.13.3 128.100.13.0
