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

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 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

The WSIS+20 Roadmap: Baby Steps in the Right Direction

The final phase of the WSIS+20 review has started. The two co-facilitators, Ambassador Suela Janina from Albania and Ambassador Ekitela Lokaale from Kenia, published on May, 21, 2025, their road map. The WSIS+20 Roadmap will lead us to the WSIS High-Level Meeting of the UN General Assembly (UNGA), scheduled for New York at the UN HQ on December 16-17, 2025. The first intergovernmental consultations were held on May 30, 2025, in New York. Two online stakeholder consultations followed on June 9 & 10, 2025. 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

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

.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

ICANN Reserves “.INTERNAL” Domain for Private Use

The Internet Corporation for Assigned Names and Numbers (ICANN) has officially reserved the top-level domain ".INTERNAL" for private-use applications. This decision follows years of technical evaluations, public consultations, and inter-organizational discussions. 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

From Toad to Princess - New TLDs Are No Magical Wand in the Kingdom of Search Engines

Google has posted details on Ranking of new gTLDs (new gTLDs) in search. John Mueller, Webmaster Trends Analyst, said that new gTLD's will be treated the same as other gTLD's such as .com. He stated: "Overall, our systems treat new gTLDs like other gTLDs (like .com & .org). Keywords in a TLD do not give any advantage or disadvantage in search." The ambiguous use of the word "overall" in the statement, may leave some doubt as to whether the 600 .brands -- new domain extensions operated by brand owners -- are included or excluded in any VIP search ranking treatment. 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

10 Noteworthy Cyberlaw Developments of 2009

While I like John Ottaviani's perspectives on 2009's top Cyberlaw developments a lot, I independently developed my own top 10 list that has a different emphasis. You might enjoy the contrasts. My list... more
