A packet bearing a destination address 144.16.68.118 arrives at the router. On which interface will it be forwarded. Additionally, you should provide a range of host IP addresses for each of the above mentioned subnet mask addresses, as well as the steps necessary to locate the appropriate interface for the given destination address (144.16.68.118). Only the interface name will not give full points.(20) b. A 3000-byte datagram (comprising 20 bytes of IP header and a 2980-byte payload) has arrived at a router and needs to be forwarded to a link with an MTU (Maximum Transfer Unit) of 700 bytes. Determine the number of fragments to be generated, along with their MF (More Fragments), offset, and total length. (20) c. How does the transition from IP4 to IP6 work? Describe briefly (10) d. Consider the following scenario in which host 10.0.0.1 is communicating with an external web server at IP address 128.119.40.186. The NAT table shows the table entry associated with this TCP flow. What are the source and destination IP address and port numbers at point A?(10)
