0 points: A message is sent from Ash's Pokedex (IP: 132.244.32.17/24; MAC: 44:FA:BC:2E:67:1B) to Misty's Pokedex (IP: 55.101.136.76/24; MAC: 1E:24:6D:D2:33:8A), both of which are on the same LAN. Draw the frames with the addresses in order as it travels from Ash to Misty.
60 points: After both Ash and Misty (with the same IP and MACs as the previous question) have left the Cerulean Gym and arrived at their own homes, Misty responds by sending Ash a message. Misty's home network (on router with internal-facing MAC: 52:4A:23:1F:A1:B6, external-facing MAC: 52:D1:1C:67:9D:12) has leased her Pokedex the IP 64.201.249.13/28, Ash's home network (on router with internal-facing MAC: 0E:F4:92:9B:10:04, external-facing MAC: 38:71:CB:B1:ED:22) has leased his Pokedex the IP 133.43.121.62/27. If their two routers are externally-connected to the same Cerulean City network, what are the four addresses going to be on each of the three frames for this message? (Put the addresses in the correct order for each message.)
