More Stepping Stones Before This Summer’s Seminal DNSSEC Events

The deployment of Domain Security Extensions (DNSSEC) has crossed another milestone this month with the publication of DURZ (deliberately unvalidatable root zone) in all DNS root servers on 5 May 2010. While this change was virtually invisible to most Internet users, this event and the remaining testing that will occur over these next two months will dictate the ultimate success of DNSSEC deployment across the Internet.

First .emarat Arabic Script Domain Name is Live!

The .emarat Arabic script Internationalised Domain Name (IDN) ccTLD for the United Arab Emirates has been entered into the DNS Root Zone and is therefore now resolving. This is a truly historic moment in the development of the Internet in the United Arab Emirates and the wider Arabic-speaking world as it removes the last hurdle preventing people without English-language skills from enjoying the full benefits that the Internet has to offer.

By the way… Your IDN is Live.

Just when you think ICANN has got it right, it shoots itself in the foot as only ICANN can. Unfortunately it seems this is yet another case of one step forward and two steps back. While we should be celebrating the fact that Internationalised Domain Names (IDN's) have finally been entered into the Root Zone, we are instead left shaking our heads at the seemingly nonexistent process lines nor communication lines between ICANN and its technical off-shoot IANA.

How to Place Top-Level Domain Trust Anchors in the Root

The project to sign the DNS root zone with DNSSEC took an additional step toward completion yesterday with the last of the "root server" hosts switching to serving signed DNSSEC data. Now every DNS query to a root server can return DNSSEC-signed data, albeit the "deliberately unvalidatable" data prior to the final launch. Another key piece for a working signed root is the acceptance of trust anchors in the form of DS records from top-level domain operators. These trust anchors are used to form the chain of trust from the root zone to the TLD.

When Registrars Look the Other Way, Drug-Dealers Get Paid

Since November of last year we have been discussing the problem of illicit and illegal online pharmacy support by ICANN-accredited Registrars. In several articles and direct contact with the Registrars we have tirelessly tried to convey the seriousness of this problem, many listened, some did not... With the background information already known, the case presented here is much more specific and concerns EvaPharmacy, which was until recently, the world's largest online criminal pharmacy network.

DNSSEC Root Signature, Almost There!

IT security specialists have known for years that the plain DNS is not to be trusted. Any hope for improvement rests on the DNSSEC protocol deployment. In this post, I will review the current status in one critical aspect, namely the DNS root signature key management. The other two foremost are the application usage of DNSSEC protocol functionality and the operational front, or the extent of deployment in the DNS infrastructure. The operational front includes the support by the DNS root nameservers, but my focus on signature key management leaves this issue aside.

One Big Cheer for ICANN - But Still a Way’s from Our “Gooool”

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 on Portable Email Addresses

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?

DNSSEC Status Report: Signing Infrastructure Well Underway, User Experience Still Needs Work

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.

Operational Challenges When Implementing DNSSEC

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.
