WHOIS Review and Beyond 3.7.8

We have posted our support of the WHOIS Policy Review Team Report with two important comments. First, on page 79 of the report it is confirmed that the RAA is unenforceable on WHOIS inaccuracy (we wrote about this while at the last ICANN meeting) because the language of RAA 3.7.8 has no enforcement provision. It is now time for ICANN to confirm this problem officially.  more

The Business Parallels Between IPv6 and DNSSEC

For two things that would seem to be completely unrelated there is an interesting parallel between IPv6 and DNSSEC. In both cases there is a misalignment of interests between content providers and service?providers. Content providers aren't highly motivated to deploy IPv6 because only a small proportion of users have v6 connectivity and even fewer only have v6. Service providers aren't anxious to deploy IPv6? because there isn't a lot of content on v6, and virtually none exclusively on v6 - so they don't expand the universe of interesting stuff on the web by deploying IPv6. Basically the same things could be said about DNSSEC. more

ICANN’s Contract Not Enforceable on WHOIS Accuracy

This may or may not come as a shock to some of you, but ICANN's contract with the Domain Name Registrars, in terms of WHOIS inaccuracy is not enforceable. Bear with me. The ability of ICANN to enforce against a Registrar who fails to correct or delete a domain with false WHOIS does not exist. more

If You Build It, They Will Come.

Only two years after signing the DNS root zone, the powerful lure of a secure global infrastructure for data distribution is starting to reveal itself. It is illustrated clearly by two proposed technical standardizations that seek to leverage secure DNS. To some degree these developments highlight the strength of DNS institutions and how they might fill gaps elsewhere in the Internet's governance. But an increasing reliance upon and concentration of power in the DNS also makes getting its global governance correct even more important. more

Spam from Mobile Networks? Who Woulda Thought…

Mobile networks aren't usually thought of as sources of spam, but a quick look at some of the resources that track spam reveals they actually are. This is counter intuitive at first glance because when most people think of mobile they think of smartphones, and those aren't known to be sources of spam (at least not yet). What's really going on is PCs connected to mobile networks with air cards, or tethered with a smartphone where it's permissible, are the culprits more

Getting On Board With DNSSEC - A Personal Recount

I first became familiar with DNSSEC around 2002 when it was a feature of the Bind9 server, which I was using to setup a new authoritative DNS platform for customers of the ISP I was working for. I looked at it briefly, decided it was too complex and not worth investigating. A couple of years later a domain of a customer got poisoned in another ISPs network. And while the DNS service we provided was working properly, the customers impression was we hadn't protected them. more

DNS Resolution, Browsers & Hope For The Future

DNS is not something that most people think about when using the Internet. Neither should they have to: the DNS is just part of the infrastructure in the same way that IP addresses are. The only time a user ought to notice the DNS is when it breaks (and it should never break). If that's true, then we ought to expect any Internet client - including web browsers - to use the very same infrastructure as everything else and for the DNS resolution mechanisms to be the ones offered by the operating system. What makes browsers different? more

Driving DNSSEC: The Need for Integration of All the Functions Needed

DNSSEC continues to gain momentum as network operators and domain owners watch and learn from early adopters. The learning process is made easier by efforts such as the ongoing work conducted by researchers at Sandia labs to methodically identify and categorize the kinds of problems that are occurring. more

DNS Changer

One fine night in November 2011 I got an opportunity to get my hands dirty, working on a project for the United States Federal Bureau of Investigation (FBI). They were planning to seize a bunch of computing assets in New York City that were being used as part of a criminal empire that we called "DNS Changer" since that was the name of the software this gang used to infect a half million or so computers. more

IPv6 DNS Blacklists Reconsidered

I opined about a year ago that DNS blacklists wouldn't work for mail that runs over IPv6 rather than IPv4. The reason is that IPv6 has such a huge range of addresses that spammers can easily send every message from a unique IP address, which means that recipient systems will fire off a unique set of DNSBL queries for every message... Now I'm much less sure this will be a problem... more

NASA Teething Troubles Teach a DNSSEC Lesson

On January 18, 2012, Comcast customers found they could not access the NASA.gov website. Some users assumed that Comcast was deliberately blocking the website or that NASA, like Wikipedia and Reddit, was participating in the "blackout" protests against the Stop Online Piracy Act (SOPA) going on that day. As it turned out, the truth was much less exciting, but it offers important lessons about DNSSEC. more

Wither WHOIS!: A New Look At An Old System

No, that title is not a typo. The WHOIS service and the underlying protocol are a relic of another Internet age and need to be replaced. At the recent ICANN 43 conference in Costa Rica, WHOIS was on just about every meeting agenda because of two reasons. First, the Security and Stability Advisory Committee put out SAC 051 which called for a replacement WHOIS protocol and at ICANN 43, there was a panel discussion on such a replacement. The second reason was the draft report from the WHOIS Policy Review Team. more

There Are at Least 10 Million DNS Resolvers on the Internet Today

In a blog post on the ICANN website, Joe Abley writes: "Resolvers are servers on the Internet which use the Domain Name System (DNS) protocol to retrieve information from authoritative servers and return answers to end-user applications... So, all in all, how many resolvers are there? Given that anybody can run one, it seems like a difficult thing to measure. It turns out, however, that all resolvers that talk directly to authoritative servers on the Internet leave a trail, and with a little data crunching we can come up with a number." more

Port 43 Failures Continue to Haunt

On February 16, 2012 ICANN took the new step of suspending the Registrar Alantron's ability to register new names or accept inbound domain transfers. This new compliance tool was used following Alantron's apparently inadequate response to a breach notice issued November 7, 2011. The issue in part concerns Alantron's perpetual problems with Port 43 WHOIS access which is required by the Registrar Accreditation Agreement. more

Growth in IPv6-Capable DNS Infrastructure

In our last post on CircleID we showed encouraging growth in the number of IPv6-enabled networks. But announcing an IPv6 prefix is only one of the first steps a network operator should take when deploying IPv6. For a full IPv6 deployment, IPv6 needs to be enabled on network infrastructure and made available to end users. One key piece of infrastructure for which we can measure IPv6 capabilities are DNS resolvers. more
