  • DNS Checker

    We have just released a new utility in the Apple app store. It tests recursive DNS servers for conformance against current DNS protocol specifications, especially with regard to EDNS(0) as specified in RFC 6891. Like our other utility on the app store, Dig, this is a free download, and we do not provide formal support for it. Ray Bellis, ISC’s

  • BIND 9 Refactoring

    The first release of BIND 9 was in September 2000. In the intervening 16 years, we have issued 225 more releases, give or take a few.  We have continuously added new additional features and RFCs. BIND 9 is a big project: at last count there were 691,554 lines of code* in BIND.  That is 3 times the size of PowerDNS, 5

  • 2017 Root Key Rollover – What Does it Mean for BIND Users?

    Executive summary If you manage a DNS resolver, you may need to take action in 2017 due to the upcoming root key rollover. If you use BIND with “managed-keys” for the root zone or “dnssec-validation auto”, there is low risk. If you use BIND with “trusted-keys” for the root zone, you need to update your configuration. Anyone setting up a new BIND instance around the

  • The Potential Operational Risks Associated with Untrusted Zone Transfers

    At the DNS Summer Day 2016  held in Tokyo on June 24th it was disclosed that an unbounded zone transfer (AXFR) operation can cause operational issues due to resource exhaustion for the server that is receiving the zone transfer.  On servers running BIND, Knot or PowerDNS the receiving server may run out of memory, and on servers running

  • BIND9 Adopts the MPL 2.0 License with BIND 9.11.0

    ISC published BIND under a very permissive open source license nearly two decades ago, and we have been maintaining it ever since. In December we announced we were changing the license for our Kea DHCP server to the modern and widely-used Mozilla Public License (MPL 2.0). The MPL 2.0 license requires that if you make changes to licensed software (e.g. BIND) and distribute

  • ISC considering a change to the BIND9 license

    ISC published BIND under a very permissive open source license nearly two decades ago. Since then, it has become the world’s most widely used nameserver. Partly, this is due to the popularity of commercial services and software based on BIND. While this is welcome, and these commercial products are undoubtedly adding value, unfortunately not all of these users are giving back to
