4 unusual facts about Comparison of DNS server software


Comparison of DNS server software

This article presents a comparison of the features, platform support, and packaging of independent implementations of Domain Name System (DNS) name server software.

•

Each of these DNS servers is an independent implementation of the DNS protocols, capable of resolving DNS names for other computers, publishing the DNS names of computers, or both.

•

They also (typically) cache the result to answer potential future queries within a certain expiration (time-to-live) period.

•

In addition, they support the TSIG protocol, which allows DNS clients to establish a secure session with the server to publish Dynamic DNS records or to request secure DNS lookups without incurring the cost and complexity of full DNSSEC support.
