BIND

BIND 9 is intended to be fully compliant with the [https://datatracker.ietf.org/wg/dnsop/documents/ IETF DNS standards and draft standards]. 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. RNDC enables remote configuration updates, using a shared secret to provide encryption for local and remote terminals during each session.

While earlier versions of BIND offered no mechanism to store and retrieve zone data in anything other than flat text files, in 2007 BIND 9.4{{cite web

BIND 10 planned to make the data store modular, so that a variety of databases may be connected.{{cite web

In 2016 ISC added support for the 'dyndb' interface, contributed by RedHat, with BIND version 9.11.0.{{Cite web|url=https://kb.isc.org/docs/aa-01420|title = Dyndb compared to DLZ}}

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.{{cite web

The BIND 4 and BIND 8 releases both had serious security vulnerabilities. Use of these ancient versions, or any un-maintained, non-supported version is strongly discouraged.{{cite book |first1=P. |last1=Hudson |first2=A. |last2=Hudson |first3=B. |last3=Ball |first4=H. |last4=Duff |title=Red Hat Fedora 4 Unleashed |page=723 |publisher=Sams Publishing |date=2005 |isbn=0-672-32792-9}} BIND 9 was a complete rewrite, in part to mitigate these ongoing security issues. The [https://www.isc.org/downloads/ downloads page on the ISC web site] clearly shows which versions are currently maintained and which are end of life.

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. The acronym BIND is for Berkeley Internet Name Domain, from a technical paper published in 1984. It was first released with Berkeley Software Distribution 4.3BSD.

Versions of BIND through 4.8.3 were maintained by the CSRG.{{cite web

Paul Vixie of Digital Equipment Corporation (DEC) took over BIND development in 1988, releasing versions 4.9 and 4.9.1. Vixie continued to work on BIND after leaving DEC. BIND Version 4.9.2 was sponsored by Vixie Enterprises. Vixie eventually founded the Internet Software Consortium (ISC), which became the entity responsible for BIND versions starting with 4.9.3.

BIND 8 was released by ISC in May 1997.

Version 9 was developed by Nominum, Inc. under an ISC outsourcing contract, and the first version was released 9 October 2000.{{cite web

The development of BIND 9 took place under a combination of commercial and military contracts. Most of the features of BIND 9 were funded by UNIX vendors who wanted to ensure that BIND stayed competitive with Microsoft's DNS offerings;{{citation needed|date=May 2014}} the DNSSEC features were funded by the US military, which regarded DNS security as important. BIND 9 was released in September 2000.

In 2009, ISC started an effort to develop a new version of the software suite, initially called BIND10. In addition to DNS service, the BIND10 suite also included IPv4 and IPv6 DHCP server components. In April 2014, with BIND10 release 1.2.0 the ISC concluded its involvement in the project and renamed it to Bundy,{{Cite web |last=Consortium |first=Internet Systems |date=2014-04-17 |title=ISC Concludes BIND 10 Development with Release 1.2 |url=https://www.isc.org/blogs/isc-concludes-bind-10-development-with-release-1-2-project-renamed-bundy/ |access-date=2023-02-12 |website=www.isc.org |language=en-us}}{{cite web| url = http://bundy-dns.de| title = Bundy, authoritative DNS and DHCP server}} moving the source code repository to GitHub{{cite web| url = https://github.com/bundy-dns/bundy| title = bundy repo at GitHub| website = GitHub| date = 29 July 2022}} for further development by outside public efforts.{{cite web
