BIND, is the most widely used Domain Name System (DNS) software on the Internet. On Unix-like operating systems it is the de facto standard.
The software was originally designed at the University of California Berkeley (UCB) in the early 1980’s. The name originates as an acronym of Berkeley Internet Name Domain, reflecting the application’s use within UCB. The software consists, most prominently, of the DNS server component, called named, contracted for name daemon. In addition the suite contains various administration tools, and a DNS resolver interface library. The latest version of BIND is BIND 9, first released in 2000.
Starting in 2009, the Internet Software Consortium (ISC) developed a new software suite, initially called BIND10. With release version 1.2.0 the project was renamed Bundy to terminate ISC involvement in the project.
The BIND 4 and BIND 8 releases both had serious security vulnerabilities. Their use is strongly discouraged. BIND 9 was a complete rewrite, in part to mitigate these ongoing security issues.
