  • DS-Lite architecture: overview and automatic configuration

    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. Both

  • A Major Improvement in BIND 9 Startup Performance

    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,

  • Launching the TechWomen Initiative – Week One

    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

  • 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)

  • Evolution of Internet Exchanges

    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. It’s

  • DNS Forwarders

    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

  • New Opportunities for Criminal Growth – Forecasting Cyber-Crime during the IPv6 Transition

     I had the fortunate opportunity to present the Wednesday Keynote at the Rocky Mountain 2011 IPv6 Summit.  The session was a slightly different angle to the normal “IPv6” presentations. We worked through how the cyber-criminal dynamics impact IPv4 networks, the cyber-criminal “arms race” is pushing IPv6 in the criminal market place, and how these factors must be considered in IPv6

  • ISC DHCP and IPv6 – the DHCPv6 story

    Numbering Computers in IPv6 Computers and other IPv6-enabled devices need a way to select which IP address they are using, just like in IPv4. IPv6 provides several ways to do this: Manual configuration Autoconfiguration (Stateless Address Autoconfiguration, or SLAAC) Cryptographically Generated Addresses (CGA) DHCPv6 (sometimes called stateful autoconfiguration) Manual configuration works the same in IPv6 as in IPv4 – the
