Domain Name Service

DNS is a service that translates domain names such as wiki.bostonlabs.co.uk to IP address such as 192.168.0.1.

DNS is a distributed database. No one server can store the database for the entire internet, so DNS severs are configured to forward DNS requests to other DNS servers. Each DNS server is responsible for a delegated zones if authority.

The DNS server used in RHEL is the Berkeley Internet Name Domain(BIND).


Basic Parameters

DNS on RHEL is based on NAMED part of the BIND package. RHEL used BIND9.7, and it can be controlled through the rndc command.
