Bringing Order to The World’s Cybrary: New TLDs Make Sense to Organize the Chaos of the Internet

There has been considerable debate on whether the Internet needs new Top Level Domains. Advertising advocacy groups have objected to the expense of re-investment in online branding. There's a lot of work involved in telling the world .BEYONCE is where you will now find all official Beyonce related information. I'm wondering, why would anyone object to some order being applied to the internet? more

Protecting Intellectual Property is Good; Mandatory DNS Filtering is Bad

It has been about six months since I got together with four of my friends from the DNS world and we co-authored a white paper which explains the technical problems with mandated DNS filtering. The legislation we were responding to was S. 968, also called the PROTECT-IP act, which was introduced this year in the U. S. Senate. By all accounts we can expect a similar U. S. House of Representatives bill soon, so we've written a letter to both the House and Senate, renewing and updating our concerns. more

The Human Factor in DDoS Attacks

Ripped from the headlines: A recent DDoS attack lasted an entire 60 days. In other news, a single site was attacked 218 times in Q2 alone. To those of us in the business of protecting Web infrastructure, these stories are hardly surprising. What's notable, though, is where they were reported, in The Financial, whose focus is banking and financial services, not technology. The reporters used the term "DDoS" as if it were as common as "hedge fund," something everyday business people, not just techies, grasp. It's this human element that caught my interest and got me thinking a little. more

Making Internet Faster: Google, OpenDNS and Others Announce Joint Effort

Google, OpenDNS, content delivery networks and other operators have announced a joint effort called "The Global Internet Speedup," to "make the Internet faster". According to the group, this collaboration will be executed via an open IETF proposed standard called "edns-client-subnet" in order to help better direct content to users thereby decreasing latency, decreasing congestion, increasing transfer speeds and helping the Internet to scale faster and further. more

The Design of the Domain Name System, Part VIII - Names Outside the DNS

In previous installments we've been looking at aspects of the design of the DNS. In today's grand finale we look at the the subtle but very knotty issue of names inside and outside the DNS. In the early years of the DNS, domain names were typically resolved to A records which were used to identify a host running a service. With the notable exception of e-mail, once the host was identified, the name no longer mattered. more

Hacking Away at the Internet’s Security

The front page story of the September 13 2011 issue of the International Herald Tribune said it all: "Iranian activists feel the chill as hacker taps into e-mails." The news story relates how a hacker has "sneaked into the computer systems of a security firm on the outskirts of Amsterdam" and then "created credentials that could allow someone to spy on Internet connections that appeared to be secure." According to this news report this incident punched a hole in an online security mechanism that is trusted by hundreds of millions of Internet users all over the network. more

ICANN’s “Unelected” Crisis

The leaked release of the European Commission's working papers on the future of Top Level Domains highlights the impending collision between adherents of the present "multistakeholder" ICANN governance model, and an ever longer list of national governments who challenge that model. At the core of the controversy is the question of how ICANN can claim legitimacy in the DNS world when none of its Directors or Officers are elected. Even worse, its only answer, when challenged legally, is that it is responsive to its contract with an agency of the U.S. Government... more

DNSSEC Takes Off in Wake of Root Zone Signing

The Domain Name System Security Extensions (DNSSEC) is a suite of IETF-developed specifications designed to validate information provided by the Domain Name System (DNS). ... When the root zone was signed in June 2010, this acted as a catalyst for TLD operators to deploy DNSSEC on their side. We have seen a gradual but significant increase in signed TLDs since then. The map in this post shows the level of DNSSEC deployment in Europe. more

Underneath the Hood: Ownership vs. Stewardship of the Internet

As is well known to most CircleID readers - but importantly, not to most other Internet users - in March 2011, ICANN knowingly and purposefully embraced an unprecedented policy that will encourage filtering, blocking, and/or redirecting entire virtual neighborhoods, i.e., "top-level domains" (TLDs). Specifically, ICANN approved the creation of the ".XXX" suffix, intended for pornography websites. Although the owner of the new .XXX TLD deems a designated virtual enclave for morally controversial material to be socially beneficial for the Internet, this claim obfuscates the dangers such a policy creates under the hood. more

Defense in Depth for DNSSEC Applications

At the time of this writing DNSSEC mostly does not work. This is not a bad thing - in fact it's expected... There is a significant last-mover advantage DNSSEC deployment (or IPv6 deployment) and that can't be helped. It's all in a good cause though - everybody knows we need this stuff and some farsighted contributors put a lot of money and other resources into DNSSEC years or decades ago to ensure that when the time comes the world will have a migration path. Sadly, this leaves current investors and application designers and developers wondering whether there's a market yet. more

Kudos to ccTLD Registries for Taking Measures to Improve Security

When I first wrote about Domain Registry Locking over a year and a half ago, Verisign was the only Registry offering a true Registry Lock Service. Of course, not long after, Neustar announced their Registry Lock Service too. Recently however, a number of ccTLD Registries have also adopted Registry Locking programs... more

ICANN Finds Its Voice

I think we are finally getting somewhere: ICANN is no longer fluttering flusteredly whenever a lobbying group sends a nastygram over the transom. Case in point: a Association of National Advertisers (ANA) that arrived a few days ago, full of bombast and muscle-flexing, demanding that ICANN immediately stop the new gTLD program until a long list of demands from the ANA were met, or else the ANA would be forced to take some Very Scary Actions... more

The Rising Technical Challenges of Networking at Home

For me, one of the more interesting sessions at the recent IETF 81 meeting in July was the first meeting of the recently established Homenet Working Group. What's so interesting about networking the home? Well, if you regard challenges as "interesting", then just about everything is interesting when you look at networking in the home! more

ICANN, the New gTLD Program, and Our Responsibility for the Internet

When ICANN approved the New generic Top-Level Domain (gTLD) Program in Singapore in June 2011, it pushed the activities in this space to a new level. I think we will all agree that everyone involved are very busy working on new gTLD applications and getting organized per the Applicant Guidebook requirements. This to be ready in time for the 12th of January 2012 ICANN new TLD Program launch date. However, good activities also brings along bad activities. more

Alignment of Interests in DNS Blocking

I've written recently about a general purpose method called DNS Response Policy Zones (DNS RPZ) for publishing and consuming DNS reputation data to enable a market between security companies who can do the research necessary to find out where the Internet's bad stuff is and network operators who don't want their users to be victims of that bad stuff... During an extensive walking tour of the US Capitol last week to discuss a technical whitepaper with members of both parties and both houses of the legislature, I was asked several times why the DNS RPZ technology would not work for implementing something like PROTECT-IP. more
