•
NSLookup - converts a domain name to its IP address and vice versa.
Ping - tests the "reachability" of a particular network destination by sending an ICMP echo request and
•
waiting for a reply.
TraceRoute - displays the path to a destination by showing the number of hops and the router
•
addresses of these hops.

tivity. A PING could be either an IP address (163.176.4.32) or Domain Name (www.netopia.com).
