In response to our customers and colleagues, ISC has chosen to remove the RTT Banding feature from BIND 9, starting with BIND 9.8.0. Other supported versions will have RTT Banding removed in their next releases.
BIND 9.8.0 is scheduled to go out on March 1st, 2011. 9.8.1 will follow around a month later.
It's a common misconception that open source software means it's unsupported, that if you want to have 7x24 support you have to buy commercial software. Nothing could be further from the truth.
The reality is that open source software is written by professional coders, is fully production quality and support is available. The major difference between commercial software and open source software is this:
A new milestone in the history and evolution of the Internet has passed: On Thursday, February 3, 2011, it was announced that the Internet Assigned Numbers Authority (IANA), steward of the Internet's reserves of unassigned IP addresses, has distributed the final blocks of IPv4 addresses to the Regional Internet Registries (RIRs). The RIRs, based in North America, Europe, Asia, South America, and Africa, will now allocate them, according to rules developed in each region, to service providers and enterprises worldwide. And then all of the IPv4 addresses will be in use.
While many of you know ISC as the maintainer of the BIND DNS server software, we have always had our hand in the DNS operations field, including operating one of the 13 DNS root servers (F.ROOT-SERVERS.NET), as well as secondaring many ccTLD and non-commercial zones for over a decade. ISC has also been at the forefront of designing and implementing DNS Security Extensions (DNSSEC) which is a mechanism to cryptographically verify that the response given to a DNS request is correct.
“I am relieved.” That lovely double entendre is what Captain Pike said to Captain Kirk at the end of last summer's most excellent reboot of the Star Trek series. I am likewise relieved to have been relieved of my long time post as President of ISC by my good friend and long associate Barry Greene. I continue at ISC as Chairman and Chief Scientist, which is the equivalent (to me) of escaping to the candy factory. When ISC was smaller, this was the half of my job I loved most.
With the world wide deployment of IPv6 in parallel with IPv4, it has become apparent that a traditional connection loop is no longer good enough.
In fact, this is a large part of the reason why Google is white listing resolvers and Yahoo only wants to return to AAAA records to DNS queries made over IPv6. The traditional connection loop does not behave well in the presence of some network errors. It introduces excessive delays when there are good alternate addresses to use.
