Limitations of Carrier Grade NAT, and Some Workarounds

Qtel, the largest carrier in Qatar (and nearly the only Internet provider) appears to connect all their users (~600K) to the Internet through just one or a very few public IPv4 addresses. 82.148.97.69 was their single public address in 2006-2007. How can network address translation (NAT) put all those users through just one IP address? more

FttH Is Not About High-Speed Internet Access - It Is About the Internet of Things

The future of our communications infrastructure will to a very large extent be based on the Internet of Things (IoT). What this means is that hundreds of millions of devices will be connected to the national broadband networks (NBN), gathering massive amounts of information and providing feedback in real time. In any single country, the electricity grid alone will have tens of millions of sensors and devices connected to deliver the energy efficiencies that we all so desperately need. 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

America Planning for the Closure of Its Copper Network

In an interesting move the FCC's Technical Advisory Council has outlined the need for setting a 'sunset' date for the closure of the circuit switched network. This is a first step that eventually could lead to the replacement of the PSTN in the USA, rather than letting the network slowly fade into oblivion the FCC proposes the bring the issue in the open so that it can be properly evaluated and discussed. more

Email in the World’s Languages - Part III

In our last instalments we discussed the various ways to encode non-ASCII character sets, of which UTF-8 is the winner, and some complex approaches that tried to make UTF-8 mail backward compatible with ASCII mail. After years of experiments, the perhaps surprising consensus is that if you're going to do international mail, you just do it. more

ICANN Names Steve Crocker as Chair of the Board

ICANN has named, Internet pioneer, Steve Crocker as new Chair of the Board. Dr. Crocker whose involvement with ICANN dates back to 2002, has also served as chair of ICANN's Security, Stability, and Advisory Committee (SSAC) until 2010. He was the SSAC liaison to the Board from 2003 to 2008, a voting member of the Board since 2008, and vice-chair of the Board since December 2010. Crocker succeeds Peter Dengate Thrush, who was Chair since 2007. Also board member Bruce Tonkin, an Australian, was named Vice Chair. He is currently the Chief Strategy Officer for Melbourne IT Limited. more

The New gTLD Chess Game

On June 20th, the ICANN board voted to move ahead with the new generic Top-Level Domains (gTLDs) program, intended to add hundreds, if not thousands of new names to the DNS root. Now what? Not even the most enthusiastic ICANN supporters think that any new TLDs will be added before the end of 2012, but there are other things going on that greatly complicate the outlook. more

Now Begins the Third Stage of ICANN’s TLD Triathlon

The ICANN community here in Singapore is celebrating after the historic vote to expand top-level domains (TLDs). And while I wouldn't begrudge anyone a few Singapore Slings, I think it's a little early to start celebrating. The marathon effort ICANN began 5 years ago isn't even close to reaching the finish line. more

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

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

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

Tucows Comments on ICANN Applicant Guidebook

The latest ICANN Applicant Guidebook was released in mid-April and covers the introduction of new generic Top Level Domains (gTLD). The introduction of new gTLDs has been an ongoing conversation for more than a decade. We have an opportunity to approve the final draft in time for consideration of the new gTLD implementation program during the ICANN Board meeting, which will be held on Monday, 20 June 2011, in Singapore. We submitted our comments yesterday and wanted to share them with you. more

Last Minute Surge of Opposition to VeriSign .NET Auto Renewal

The current .NET Registry Agreement between ICANN and VeriSign is due to expire on 30 June 2011. On April 11 2011 ICANN posted a proposed draft renewal agreement for public comment. Under the terms of the existing agreement, which contracted a 6 year term starting July 1 2005, renewal is automatic unless VeriSign commits some egregious breach of terms. more

Slippery Slope

Last week, I visited Budapest to deliver a speech at the ICANN Studienkreis, an annual conference where experts study and address some current issues relating to Internet governance. I discussed how the Internet is on a slippery slope. Starting with the legitimate concern over how to deal with cybersquatters, we have moved to an unreasonable focus on legal control of Internet content and the domain name system. more

9 Thoughts on Stepping Up Spam and Malware Enforcement

In a tweet, EU commissioner for the Information Society Neelie Kroes congratulates OPTA on the spam fine for the golf ball printing company Backsound. Since 2004 the Dutch OPTA is the number one spam and malware fighter of the EU with a total of €1.9 million in fines. It made me ask two question to myself: How come that we seldom hear of other spam fines in the EU? And can the EU change this in any way? more
