Bob has a host computer with an IP address of 10.0.1.100/24 with a default gateway of 10. host network is connected to Steve's network which has an IP addressing scheme 192.168. 0.X/24

which has a default gateway of 192.168.0.1

a) On June 1, 2013, Bob pings the local IP address 10.0.1.200 from his host computer, Bob gets the following:

C:\ping 10.0.1.200

Request timed out.

Request timed out.

Request timed out.

Bob checks his network but makes no changes. Steve does some checking on his network, the only change Steve makes is to turn on a host device which has an IP address of 192.168.0.121/24 default gateway 192.168.0.1. No other change was made to either network. Bob attempts to ping 10.0.1.200 again - Bob now gets the following:

C:\ping 10.0 1.200

Reply from 10.0.1.200: bytes-32 time=l2ms TTL 64

Reply from 10.0.1.200: bytes=32 time=18ms TTL=64

Reply from 10.0.1.200: bytes=32 time=7ms TTL=64

Explain in detail what is occurring and why Bob now gets a reply. (10 points)

b) On June 10, 2013, Bob has no problem connecting to devices on Steve's network (everything appears to be working perfectly). When Bob tries to ping any device on Steve's network he gets "Request timed out". Explain what is going on.
