BIND

BIND, or the Berkeley Internet Name Daemon, is Article description::a popular free software DNS server, and also one of the most frequently used name servers on the Internet.

With BIND, users are able to set up a name server for managing their own DNS records, for caching DNS, or acting as a slave DNS server. The software supports DNSSEC which provides cryptographic signatures on the DNS records as a means to natively authenticate the integrity and ownership of the records.

Installation
BIND is offered through the package. As with most packages, it is good practice to check the USE flags before emerging. Since BIND is a popular name server software, it is also a popular target for hackers and malicious groups. Is wise to securely configure BIND, which includes building in support for only features that will be actually used. If a feature will not be used, reduce the surface area of security vulnerabilities by disabling it.
