New ICANN Requirements for New gTLDs Are Irrelevant

ICANN is barking up a number of wrong trees with the latest version of its Evaluation and Questions Criteria for generic top-level domains (gTLDs). The document asks for financial projections, the applicant's goals for its TLD, and the benefits the applicant expects to derive. All that information is meaningless. more

Two Stage Filtering for IPv6 Electronic Mail

I'm a guest at the MAAWG conference in San Francisco this week and several people have now mentioned to me the problem and the opportunity of anti-spam e-mail filtering for IPv6. Tomorrow is World IPv6 Day but since a bunch of the pieces have clicked together in my head I'll post this a day early. more

How Many IPv4 Addresses Does the RIPE NCC Have Left?

Since IANA ran out of IPv4 addresses, people are increasingly aware of how short the remaining lifetime of IPv4 is. With World IPv6 Day taking place this week, the issue has come into even sharper focus. Since March 2011, the RIPE NCC has been publishing the size of its pool of available IPv4 addresses. All five Regional Internet Registries (RIRs) regularly publish the status of their IPv4 address pools. In the image below, you can see how the number of IPv4 addresses in the RIPE NCC pool changes over time. more

India: One Country, Many Internationalized Domain Names

If you're interested in learning more about Internationalized Domain Names (IDNs), UNESCO and EURid recently released a report on the evolution and challenges of IDNs. It's a good read and it highlights some of the struggles that countries and registries face and taking IDNs mainstream. Though Russia has so far proven to be a major success story - with more than 800,000 IDN registrations so far (and counting) - most other IDNs are have a long ways to go yet. more

“Is DSL Finally Dying?” No!

Jeff Heynan at Infonetics reported a double-digit drop in DSL equipment sales, inspiring Dan O'Shea at Telephony to headline "Is DSL Finally Dying?" Both note that DSL sales in Q1 were actually ahead of the same quarter last year. Yet Dan writes "Fiber is the future." more

Who Cares About 50,000 .CAT’s?

This past May 19th, 5 years after its sunrise, puntCAT arrived at the 50,000 domain names landmark. We know that, nowadays, 50,000 domain names may hardly be described as shocking news, and, certainly, this is not our limit, and we believe there's still plenty of room for .cat to grow. Then, who and why should care about this number? more

DHCP for IPv4 vs. IPv6 - What You Need to Know

Dynamic Host Configuration Protocol (DHCP) is a protocol intended to enable machines (servers, game consols, etc) wishing to be "online" the ability to request Internet Protocol information from a DHCP server automatically. ... In this article we will begin to outline some of the fundamental differences between DHCPv4 and DHCPv6, explore historical uses of DHCPv4 and how those concepts will adapt/change in IPv6. more

New gTLDs: Will Application Developers Be Ready In Time to Secure User Confidence?

Last week I pointed out a potential problem with the user experience, if, as envisioned, a large number of new generic Top-Level Domains (gTLDs) are added to the root at the same time. The problem I was referring to has nothing to do with the new gTLDs themselves. Rather, it's about the lack of any updated procedures and communication campaigns to application and software vendors. The objective would be to alert them in time and equip them to swiftly update their programs... more

ICANN Releases gTLD Applicant Guidebook

Per their timeline, ICANN released the gTLD Applicant Guidebook on May 30th. This version contains revisions based upon both community feedback, as well as recent consultations with the Governmental Advisory Committee (GAC). more

What is Internet Protocol Address Management?”

The number of web-based devices is expanding at an exponential clip, virtualization is making a very static environment dynamic, and now with the exhaustion of IPv4 and the oncoming complexities of IPv6 network operators must reevaluate what IP Address Management (IPAM) really is. The goal of this post is to define the various functions that make up IP Address Management. more

Anycast, Unicast, or Both?

A long time ago in an Internet far away, nobody paid for DNS services. Not directly at least. We either ran our own servers, or got DNS service as part of our IP transit contract, or traded services with others. In ~1990 I was the operator of one of the largest name servers in existence (UUCP-GW-1.PA.DEC.COM) and I exchanged free DNS secondary service with UUNET. Two thousand zones seemed like a lot of zones back then -- little did we dream that there would some day be a billion or so DNS zones world wide. more

Solving the Spam Problem

Last week, I read Ed Falk's blog post where he commented on a possible solution to the spam problem. He himself was commenting on a study done by researchers out of the University of California where they discovered that credit card transactions for stuff bought in spamvertisements are handled by three companies: one in Azerbaijan, one in Denmark and one in the West Indies. Presumably, if security experts and law enforcement went after these companies, spammers would have their financial supply cut off. No money = no incentive to spam. more

The gTLD Boondoggle

I've been watching at the excitement build in the domain community, where a lot of people seem to believe that at next month's Singapore meeting, by golly, this time ICANN will really truly open the floodgates and start adding lots of new Top-Level Domains (TLDs). I have my doubts, because there's still significant issues with the Governmental Advisory Committee (GAC) and the US Government and ICANN hasn't yet grasped the fact that governments do not defer to NGOs, but let's back up a little and ask is this a good idea. more

RSA Breach Fallout?

Back in March, it was widely reported that RSA had suffered a serious security breach that (to some extent) weakened the security of its SecurID token. However, the NY Times reported then that the chairman said that the penetration wasn't absolute but "it could potentially reduce the effectiveness of the system in the face of a 'broader attack.'". more

IP Addressing in the New Age of Scarcity

This is the prepared opening statement given on behalf of Depository, Inc. at the panel discussion "IP addressing in the new age of scarcity" in the context of Internet governance and public policy at the Global Internet Governance: Research and Public Policy Challenges for the Next Decade Regional Conference held at the American University School of International Service on Thursday, May 5th, 2011 between 11:00 a.m. to 12:15 p.m. with Prof. Milton Mueller moderating and on the panel as well was John Curran, President and CEO of ARIN and Michael Froomkin, Professor of Law, University of Miami School of Law. more
