BIND is the most widely used DNS software on the internet and the de facto standard on Unix-like operating systems.

"BIND is open source software that implements the Domain Name System (DNS) protocols for the Internet"(https://www.isc.org/software/bind). "Originally written by four graduate students at the Computer Systems Research Group at the University of California, Berkeley (UCB), the name originates as an acronym from Berkeley Internet Name Domain, reflecting the application's use within UCB"(http://en.wikipedia.org/wiki/BIND). It is the de facto standard DNS software on all Unix-like systems which includes Ubuntu as well.
