Answer / rajesh
B. DNS is utilized primarily on the Internet for resolution of
the name/address of the web site. It is an Internet service
that translates domain names into IP addresses. As names are
alphabetic, they are easier to remember. However, the
Internet is based on IP addresses. Every time a domain name
is used, a DNS service must translate the name into the
corresponding IP address. The DNS system has its own
network. If one DNS server does not know how to translate a
particular domain name, it asks another one, and so on,
until the correct IP address is returned.

Answer / ca ramesh chandra giri
Correct Answer is C. IP addresses for the Internet.
Reason
Domain Name Servers (DNS) are the Internet's equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.
