Part 1: nslookup

  1. Click on the magnifying glass in the Windows taskbar and type ‘cmd’. Open the Command Prompt application that pops up.
  2. The command nslookup is used to find the IP address of a host and the hostname for an IP address.
  3. Type into the command prompt window nslookup champlain.edu The IP address shown in the ‘Non-authoritative answer’ portion is Champlain’s web server next to “Addresses” Copy the output to your GitHub submission and put asterisks next to the IP Address(es).
C:\Users\zachary.morris>nslookup champlain.edu
Server:  ns.champlain.edu
**Address:  216.93.145.253

Name:    champlain.edu
**Address:  208.115.107.132

Part 2: Ping

Type ping x.x.x.x into your command prompt, replacing x.x.x.x with the Champlain.edu IP address you found in Part 1. Let the program run to completion. Copy the output to your GitHub submission and put asterisks next to the IP Address(es).

C:\Users\zachary.morris>ping 208.115.107.132

Part 3: Tracert (Where in the world in Champlain’s web server?)

Now, type tracert -d www.champlain.edu in your command prompt. The switch -d will not resolve hostnames so it runs faster. Let the program run to completion, and copy the output into your GitHub lab submission.

C:\Users\zachary.morris>tracert -d www.champlain.edu
