As we approach the World Cup in South Africa this June it's heartening to see the amount of attention being paid to the continent. As with ICANN's recent Nairobi meeting, the eyes of the world are focusing on Africa in a new way -- as a sophisticated marketplace, and as a destination for investment, technology, and yes, sports... Still, as we prepare for the Cup and as we celebrate ICANN's recent approval of more Internationalized Domain Names (IDNs), our job as an Internet community remains unfinished. Too many scripts and thus too many key voices remain "off the pitch". more
Last month a bill in the Israeli Knesset would have required ISPs to provide portable e-mail addresses, analogous to portable phone numbers that one can take from one phone company to the other. As I noted at the time, e-mail works differently from telephone calls, and portability would be difficult, expensive, and unreliable. So I was wondering, idly, if we really wanted to provide portable e-mail addresses, how hard would it be? more
The registries (gTLDS) are all moving towards signing in about a year. PIR and .org is going to be first with .edu, .biz, and others closely behind. The root is scheduled to be signed in the beginning of July (end of June looking at the holiday calendar) being the biggest milestone. Some of the roots already contain DNSSEC information. Other ccTLDs continue to turn DNSSEC on with countries on every continent signed. more
As a reader of this article, you are probably familiar with the DNS cache poisoning techniques discovered a few years ago. And you have most likely heard that DNSSEC is the long term cure. But you might not know exactly what challenges are involved with DNSSEC and what experience the early adopters have gathered and documented. Perhaps you waited with our own rollout until you could gather more documentation over the operational experience when rolling out DNSSEC. This article summarizes authors' experiences and learnings from implementing the technology in production environments as well as discusses associated operational issues. more
Complete DNSSEC implementation requires that domains are authenticated at the root by the Registry, and that DNS zones and records are authenticated as well. Now before I go any further, let me begin by stating that I fully support the development and deployment of DNSSEC and that the vulnerabilities presented by Cache Poisoning are very real, especially for those websites collecting login credentials or other types of sensitive information. more
You may have seen media reports a few weeks ago describing how servers behind the so-called Great Firewall of China were found delivering incorrect DNS information to users in the rest of the world, thereby redirecting users to edited Web pages. Reports indicate that this apparently occurred due to a caching error by a single Internet Service Provider. While the problem was fairly limited in scope, it could have entirely been prevented in a world where DNSSEC was fully deployed. more
The year 2010 is turning out to be the "year of DNSSEC" from Registry implementations, Registrar implementations, ISP support, to the Root being signed this summer. Because we are dealing with such critical infrastructure, it is important to not lose sight of careful implementations. more
With advancements in hardware and software, sophisticated filtering technologies are increasingly being applied to restrict access to the Internet. This happens at the level of both governments and corporations. .. given the open nature of the trust-based Internet, one country's restrictions, if not handled very carefully, can easily foul the global Internet nest we all live in. This blog is about one such story of Internet restrictions in China becoming visible (seemingly at random) from other parts of the world and going undetected for 3 weeks. more
The IDN ccTLD Fast Track program is moving along rapidly, with ICANN's announcement that both the Simplified and Traditional Chinese script versions of .china have passed the string evaluation phase of the IDN ccTLD Fast Track Program. Alongside this, ICANN have also announced the release of a proposed implementation plan for 'Synchronised IDN ccTLDs' that will create the rules by which these variant IDN ccTLDs will coexist. more
Yesterday's Wikipedia outage, which resulted from invalid DNS zone information, provides some good reminders about the best and worst attributes of active DNS management. The best part of the DNS is that it provides knowledgeable operators with a great tool to use to manage traffic around trouble spots on a network. In this case, Wikipedia was attempting to route around its European data center because... more
