Who Uses Google’s Public DNS?

Much has been said about how Google uses the services they provide, including their mail service, their office productivity tools, file storage and similar services, as a means of gathering an accurate profile of each individual user of their services. The company has made a very successful business out of measuring users, and selling those metrics to advertisers. But can we measure Google as they undertake this activity? How many users avail themselves of their services? Perhaps that's a little ambitious at this stage, so maybe a slightly smaller scale may be better. Let's just look at one Google service. more

Technical Viability of Dotless Domain Names

It was never obvious at the outset of this grand Internet experiment that the one aspect of the network's infrastructure that would truly prove to be the most fascinating, intriguing, painful, lucrative and just plain confusing, would be the Internet's Domain Name System. After all, it all seemed so simple to start with: network applications rendezvous with their counterparts using protocol-level addresses, but we users prefer to use "natural" identifiers that act as aliases for these addresses. more

Google DNS to Be Discontinued in Brazil Ahead of New Law

Doug Madory from Renesys reports: "In response to recent NSA spying allegations, Brazil is pressing ahead with a new law to require Internet companies like Google to store data about Brazilian users inside Brazil, where it will be subject to local privacy laws. The proposed legislation could be signed into law as early as the end of this week. However, Google's DNS service started leaving the country on September 12th, the day President Rousseff announced her intention to require local storage of user data." more

ICANN at the Inflection Point: Implications and Effects Of the GAC Beijing Communique

Although this article was first published just a few days ago, on May 8th, there have been several important intervening developments. First, on May 10th ICANN released a News Alert on "NGPC Progress on GAC Advice" that provides a timetable for how the New gTLD program Committee will deal with the GAC Communique. Of particular note is that, as the last action in an initial phase consisting of "actions for soliciting input from Applicants and from the Community', the NGPC will begin to "Review and consider Applicant responses to GAC Advice and Public Comments on how Board should respond to GAC Advice... more

What New gTLD Applicants Need Is a Quick, Lightweight Answer to the World’s Governments. Here It Is.

It's safe to say that with just a week to go before ICANN intended to sign the first contract for a new gTLD, the last thing anyone wanted was a 12-page document from the world's governments with 16 new "safeguards", six of which it wants to see applied to every new extension. But what the industry shouldn't overlook, especially in the face of the expected critical responses this week and next, is that the Governmental Advisory Committee's (GAC's) formal advice from the ICANN Beijing meeting represents an opportunity for the domain name industry to lock-in self-regulation at a critical point in its evolution. more

The Spamhaus Distributed Denial of Service - How Big a Deal Was It?

If you haven't been reading the news of late, venerable anti-spam service Spamhaus has been the target of a sustained, record-setting Distributed Denial-of-Service (DDoS) attack over the past couple of weeks... Of course, bad guys are always mad at Spamhaus, and so they had a pretty robust set-up to begin with, but whoever was behind this attack was able to muster some huge resources, heretofore never seen in intensity, and it had some impact, on the Spamhaus website, and to a limited degree, on the behind-the-scenes services that Spamhaus uses to distribute their data to their customers. more

Reducing the Risks of BYOD with DNS-Based Security Intelligence; Part 1: Understanding the Risks

Ah, BYOD. How I love thee. BYOD, or "Bring Your Own Device", gives me choices. I can use a device at work I actually like and am most effective with. (How did I ever get by without my iPad?) But BYOD comes with challenges. Personal devices can be infected with malware. Once they're connected to an enterprise's network, they can be controlled by a bot master to hijack enterprise resources and wreak havoc as part of a botnet. more

Follow a Phishing Case in Real Time: postfinances.com / Swiss Post

It is just another phishing case. Why should I care? I happened to receive my own copy of the phishing email message. Most Internet users will just smile bitterly before deleting it. I checked it to see why it had gone through the spam filters. It had no URL in the text but a reply-to address. So it needed a valid domain name, and had one: postfinances.com. PostFinance (without trailing "s") is the payment system of the Swiss Post. It has millions of users. more

NTIA Awards IANA Functions Contract to ICANN

The U.S. Commerce Department's National Telecommunications and Information Administration (NTIA) announced today that it has awarded the Internet Assigned Numbers Authority (IANA) functions contract to the Internet Corporation for Assigned Names and Numbers (ICANN). The IANA functions are key technical services critical to the continued operations of the Internet's underlying address book, the Domain Name System (DNS). 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

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

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

Feds Ask for DNSChanger Deadline Extension As Millions of PCs Could Be Cut Off from the Web

Brian Krebs reporting in Krebs on Security: "Millions of computers infected with the stealthy and tenacious DNSChanger Trojan may be spared a planned disconnection from the Internet early next month if a New York court approves a new request by the U.S. government. Meanwhile, six men accused of managing and profiting from the huge collection of hacked PCs are expected to soon be extradited from their native Estonia to face charges in the United States." more

Is ICANN Opening up Public Comment Periods in Bad Faith?

I read with interest that ICANN opened up yet another comment period on new TLDs. I believe that I speak for many when I question whether ICANN is opening up these comment periods in good faith, or instead whether these are smokescreens, mere distractions to pretend that ICANN is "listening" to the public while staff and insiders proceed with predetermined outcomes. more
