Important features of BIND 9 include: TSIG, nsupdate, IPv6, RNDC (remote name daemon control), views, multiprocessor support, Response Rate Limiting (RRL), DNSSEC, and broad portability.

[10] Security issues that are discovered in BIND 9 are patched and publicly disclosed in keeping with common principles of open source software.

A complete list of security defects that have been discovered and disclosed in BIND9 is maintained by Internet Systems Consortium, the current authors of the software.

BIND was originally written by four graduate students at the Computer Systems Research Group (CSRG) at the University of California, Berkeley, Douglas Terry, Mark Painter, David Riggle and Songnian Zhou, in the early 1980s as a result of a DARPA grant.

Vixie eventually founded the Internet Software Consortium (ISC), which became the entity responsible for BIND versions starting with 4.9.3.

[14] It was written from scratch in part to address the architectural difficulties with auditing the earlier BIND code bases, and also to support DNSSEC (DNS Security Extensions).

In April 2014, with BIND10 release 1.2.0 the ISC concluded its involvement in the project and renamed it to Bundy,[15][16] moving the source code repository to GitHub[17] for further development by outside public efforts.
