The nslookup command displays the IP address associated with a given host name.

To do this, it checks the local domain name server.

To do this, type "nslookup hostname" (where hostname is the name of the computer that you are looking up).

You should see both the IP of the name server and the IP of the host - make sure to use the right one.

You can do this from the Windows Command Prompt or the command prompt on a Linux machine. I think you have to use the Network Utility on an Apple machine.

For each statement below, say whether it applies to a Virtual LAN (VLAN) or a Virtual Private Network (VPN). (2 pts)

______ Provides privacy while using the public internet

__ ___ Creates broadcast domains logically, rather than geographically
