Footprirvting a Target Network .p4

23. Repeat the above step until you reach the IP address for www.certifiedhacker.com (111 this case, 202.75.54.101)

FIGURE 1.13: The ping command for www.certifiedhacker.com with —i 10 —n 1 options

24. Here the successful ping to reach www.certifiedhacker.com is 15 hops. The output will be similar to the trace route results

25. Now, make a note of all die IP addresses from which you receive the reply during the ping to emulate tracert

Lab Analysis

Document all die IP addresses, reply request IP addresses, and their TJL'Ls.

Questions

1. How does tracert (trace route) find the route that the trace packets are (probably) using?
2. Is there any other answer ping could give us (except those few we saw before)?
3. We saw before:
י Request timed out
י Packet needs to be fragmented but DF set
י Reply from XXX.XXX.XXX.XX: TI L expired 111 transit What ICMP type and code are used for the ICMP Echo request?
4. Why does traceroute give different results on different networks (and sometimes on the same network)?
