DS-Lite architecture: overview and automatic configuration

09 Aug 2011
Tomasz Mrugalski

Dual Stack Lite is an architecture that allows IPv4 services to be provided in an IPv6 network, despite a limited amount of available IPv4 addresses. Work on DS-Lite was conducted within the Softwires working group in the IETF, and began in late 2008. After many revisions it was recently published as RFC6333, with its companion RFC6334 dedicated to automated configuration.

A Major Improvement in BIND 9 Startup Performance

12 Jul 2011
by Evan Hunt

One of the common complaints we've received over the years about BIND 9 is that large authoritative servers, particularly those with a very large number of small zones, are slow to launch. I've met some DNS operators who expressed a powerful aversion to upgrading their systems, because a shutdown and restart can literally take all day.

If that describes you, I have some good news. There is a simple optimization for BIND 9 that can dramatically improve your startup performance.

Launching the TechWomen Initiative - Week One

10 Jun 2011
Larissa Shapiro

I am deeply honored to be participating as a technical mentor for the TechWomen project this summer. TechWomen is a project born out of President Obama's 2009 Cairo speech, where he called for greater collaboration in technology between the United States and countries with majority Muslim populations.

TechWomen is funded by the U.S. Department of State’s Bureau of Educational and Cultural Affairs (ECA), managed by the Institute of International Education (IIE), and implemented in partnership with the Anita Borg Institute for Women in Technology (ABI).

BIND 10 & DHCP

BIND 10

BIND 10 is the next generation version of BIND, ISC's DNS server. We have a long list of ways that we wanted to improve on BIND 9, including scalability, reliability, modularity, extensibility, and usability. The project to build BIND 10 has been active for the past 2 years, and now has a usable (though not yet production ready) server.

Evolution of Internet Exchanges

Keith Mitchell

Something we're fortunate to have at ISC is the founders of some of the most influential Internet Exchanges (IXPs) amongst our senior staff. I haven't been personally involved in the IXP business for around 7 years now, so it was a pleasure to be invited as guest speaker to the AGM of the TorIX, Canada's biggest IXP, in Toronto.

DNS forwarders

29 Apr 2011
Jelte

Recently, at a BIND 10 Face to face meeting, we scheduled a short slot of time to discuss the features of a DNS forwarder. As part of the development process of the BIND 10 recursive resolver, we initially implemented a basic forwarder. As we added actual recursive resolver features, the original 'forwarding' mode was left in, and got some of the features that were added for the 'resolving' mode, mostly on an ad-hoc basis.
