Registration Operations Association Workshop Update

In a series of recent blog posts I've described the technical challenges in registration operations, a proposal for an industry association, and announced an interactive workshop to explore association formation. This is an update on where things stand with the workshop. The first Registration Operations Association Workshop is scheduled for Thursday, 16 October 2014 in the Pacific Palisades room at the Los Angeles Hyatt Regency Century Plaza hotel, the same venue being used for ICANN 51. more

Confirmed: Bill Clinton to Address ICANN Meeting in SF

A personal source close to Bill Clinton has confirmed to us that the former president will give the keynote speech ICANN meeting in San Francisco March 14-18. The meeting promises to produce far more electricity than sleepy NGO-lawyer-techie-academic-lobbyist ICANN attendees are used to. 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

LTE and Spectrum Stupidity

Mobile operators are counting on Long Term Evolution (LTE) technology to handle surging demand for mobile data access. But LTE developers made some poor choices, cutting spectral efficiency and thus driving up operator costs. LTE was envisioned as an all IP system, but the RF allocations follow the voice-centric approach of earlier generations. While LTE standards allow for either Frequency Division Duplexing (FDD) or Time Division Duplexing (TDD), all initial LTE equipment uses FDD. FDD requires two separate blocks of spectrum... more

RIPE NCC Publishes Case Study of youtube.com Hijack

As you may be aware from recent news reports, traffic to the youtube.com website was 'hijacked' on a global scale on Sunday, 24 February 2008. The incident was a result of the unauthorised announcement of the prefix 208.65.153.0/24 and caused the popular video sharing website to become unreachable from most, if not all, of the Internet. The RIPE NCC conducted an analysis into how this incident was seen and tracked by the RIPE NCC's Routing Information Service (RIS) and has published a case study... more

DNSSEC Deployment Among ISPs: The Why, How, and What

It's no secret that Comcast has been leading the charge of DNSSEC deployment among ISPs. For the past couple years, Comcast has been testing and pushing for the widespread adoption of DNSSEC. In the spirit of increasing adoption, I thought I would interview the DNS gurus at Comcast to see what they've learned and what advice they would give other ISPs considering DNSSEC deployment. more

The Dot Green gTLD and the Domain Name Delusion That Foretells General gTLD Disaster

I admire Annalisa Roger. I know from my single email interaction with her that she means well. Nonetheless, dot Green apparently ranks below 330 in the list of operational new gTLDs with an apparent total of 117 domains, give or take a few. Why is this the case? It seems to me that dot Green is one the few new gTLDs that actually deserves support... The notion that most generic gTLDs [like dot Green] are already positioned to accommodate brand channel partners such as this or that 'brandchannel.green' is illusion. more

Graph Shows Decline of IPv4 Has Been Mostly Linear

As the free pool of IPv4 addresses reaches its end, we looked at the evolution of the amount of unassigned IPv4 address space over time. By 'unassigned', we mean address space not yet allocated to a Local Internet Registry (LIR) or assigned to an end user. LIRs are typically Internet Service Providers or enterprises operating an IP network. See our findings in the graph below... more

The Demand and Supply Imbalance in Telecoms

You can't open a newspaper today, listen to the radio, or watch TV without hearing about the enormous explosion in the use of telecommunications technology - be it fixed or mobile broadband, the internet, social media, smartphones, tablets, wearables, IoT, cloud computing, the list is endless... Yet, at the same time, many telcos and ISPs are struggling to maintain their profitability. This defies economic logic. more

.google Before Christmas

I'm a real fan of the Google Masterplan since its publication in 2005. After the introduction of its own global DNS I thought it might be a good idea to have a second look on the G-Masterplan. What I found is astonishing and shows the steps to .google. more

Response to Inaccurate .travel Wild Card Assessments

Bret Fausett's recent assessment of Tralliance's ".museum-like" wild card is just dead wrong. If Tralliance is so focused on monetizing its search results, why, then, would we not capitalize on the cornerstone of our registry, directory.travel? The fact is .travel is a sponsored space on the Net that is designed to do one thing and one thing only: Serve its constituency. For years the community has heard me at the open forum microphone reminding the ICANN board of directors that the industry was anxious to have its own domain to enable it to improve business efficiency... more

What Next for Email Service Providers?

It's been a very bad month for ESPs, companies that handle bulk mailings for their clients. Several of them have had internal security breaches, leaking client information, client mailing lists, or both. Many have also seen clients compromised, with the compromised credentials used to send spam. The sequence of events suggests all the ESPs whose clients were compromised were themselves compromised first. (That's how the crooks knew who to attack.) more

Making Sense of Google’s .xyz gTLD Branding

Google has a newly created parent, a holding company that is now its official owner. Of course, Google will keep using its extremely well-known name for its core search and related businesses. But the company now operates under an entity known as Alphabet -- to give its name with extension, Alphabet.xyz. Here specialists in gTLDs may be scratching their heads. Why .xyz? Why this little-known domain for one of the world's great corporations? more

The ITU and IPv6 Transition: Controversy at the IGF

At today's "Managing Critical Internet Resources" session of the Internet Governance Forum 2009, the ITU agenda on taking a role in IPv6 distribution once again reared its ugly head. In a heated exchange, Professor Dr Sureswaran Ramadass, the Director of Nav6 an ITU consultant/fanboy squared off with the new ICANN CEO about competition in IPv6 address distribution. more

Another Portent of the Decline and Fall of the Telco

The Swedish carrier group Telia has recently announced the sale of its international wholesale business to Polhelm Infra, an infrastructure investment manager jointly owned by a number of Swedish pension funds. Why would a telco operator sell off what was a core part of its operation to a pension fund? The Internet was originally conceived as a telephone network for computers. (I should mention that this was not a concept that was unique to the Internet at the time. more
