Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address.

A forward lookup zone is a DNS zone in which hostname to IP address relations are stored. When a computer requests the IP address of a specific hostname, the forward lookup zone is queried and the result is returned.

Reverse Lookup Zone that means it resolves IP Address to
Fully qualified domain name.
for Ex. 192.168.34.23 to resolve www.admin.com

Answer / ravi

Forward lookup zone resolves domain name into ip address.
example: try this in nslookup. in that if you give domain

Reverselookup zone resolves Ip into domain name. try this
same as forward lookupzone. but give ip address. it resolves
to domain name.

these all are performed with DNS server. without DNS server
it doesn't.

A forward lookup zone is a DNS zone in which hostname to IP
address relations are stored. When a computer requests the
IP address of a specific hostname, the forward lookup zone

A reverse lookup zone does just the opposite. When a
computer requests the hostname of an IP address, the
reverse lookup zone is queried and the result is returned.
