2. • Mapping a name to an address or an address to a
name is called name-address resolution.
• A host that needs to map an address to a name to an
address calls a DNS client called resolver.
• The resolver accesses the closet DNS server with a
mapping request.
• If the server has the information, it satisfies the
resolver ; otherwise , it either refers the resolvers to
other servers to provide the information.

3. • In UNIX & Windows, the nslookup utility can be
used to retrieve address/name mapping.
• If we have the domain name we get the IP address of
that domain using the nslookup utility as shown :-
$ nslookup fhda.edu
Name: fhda.edu
Address: 153.18.8.1

4. The nslookup utility can also used to retrieve the
domain name when the address is given below :-
$ nslookup 153.18.8.1
1.8.18.153.in-addr.
