Lab Experiments: 1. Develop a list of at least 5 web sites and 5 email servers that you think are geographically dispersed across the Internet. 2. Using DNS (program called nslookup or dig) lookup the IP addresses of each of the sites from experiment 1. For the email servers you will need to set the DNS query type to MX. See the man page for running the program. 3. Using the same program lookup the names of machines with IP address close to the IP addresses of the web sites (use the same first three octets of the IP address and vary the last octet). How could an attacker use this process? 4. Using the program traceroute on a UNIX-based computer or tracert on Windows-based computer find the path from a host on your network to the servers listed in experiment 1.

Unformatted text preview: a. Using the data returned draw a diagram of the paths out to these sites. b. Can you determine the geographical region of where these sites are located? c. How many of the routers are part of your organizations network? d. Can you determine the name of your Internet Service Provider (ISP)? 5. Using the program ping determine the average round trip time for packets going to the servers listed in experiment 1. a. Comment on propagation time versus your distance from the servers. b. Comment on why some servers may not have answered the ping request. 6. The command “netstat –a” will show all connections on your computer. Use the command to identify the four-tuple used to identify each client server connection....
