Filtering Spam at the Transport Level

An interesting new paper from the Naval Postgraduate School describes what appears to be an interesting new twist on spam filtering, looking at the characteristics of the TCP session through which the mail is delivered. They observe that bots typically live on cable or DSL connections with slow congested upstreams. ... This paper tries to see whether it would be practical to use that info to manage spam in real time. more

Clues about the Future of TV

A recent article chronicles the telcos' slow start in cable TV. I don't think the telcos stand a chance of succeeding in cable TV. Instead, if they're to succeed at all, they'll probably buy or form alliances with existing cablecos... But they'd better start swimming, because the times are a changing.. more

Google Drops Out of Pentagon’s $10B Cloud Competition, Says Deal May Clash With Its AI Values

Alphabet Inc.'s Google has announced that it will not compete for the Pentagon's cloud-computing contract with an estimated value of $10 billion; says the project may conflict with its corporate values on artificial intelligence. more

More on Portable Email Addresses

Last month a bill in the Israeli Knesset would have required ISPs to provide portable e-mail addresses, analogous to portable phone numbers that one can take from one phone company to the other. As I noted at the time, e-mail works differently from telephone calls, and portability would be difficult, expensive, and unreliable. So I was wondering, idly, if we really wanted to provide portable e-mail addresses, how hard would it be? more

The Role of a Cybersecurity Czar

For years now, there have been calls for a high-level cybersecurity official, preferably reporting directly to the president. This has never happened. Indeed, there is a lot of unhappiness in some circles that President Obama has not appointed anyone as "czar" (or czarina), despite the early fanfare about the 60-day cybersecurity review. There are many reasons why nothing has happened... more

New gTLDs: Let the Gaming Begin (Part I - TLD Front Running)

A series of recent applications for national trademark rights in terms that correspond to likely strings for new top-level domain names, or TLDs, (e.g., ".BLOG") highlight just one way in which ICANN's new generic TLD (gTLD) application process is likely to be "gamed." But it is also a strategy to which some trademark holders may feel compelled to resort to defend their rights to that string. Unfortunately, it does not appear that ICANN is addressing these important public policy considerations. more

ICANN Paints Itself Into a Corner

ICANN recently commissioned a report from a domain auction company to see whether it would be a good idea to auction Top-Level Domains (TLDs) that have multiple applicants. Remarkably, the domain auctioneers came to the conclusion that auctions are a great idea, which they surely are for some people. But are they a good idea for ICANN? And if ICANN admits they can't evaluate competing applications on their merits, how can they keep the process from turning into another speculative land grab? more

Network Design: If You Haven’t Found the Tradeoff…

This week, I ran into an interesting article over at Free Code Camp about design tradeoffs... If you think you've found a design with no tradeoffs, well... Guess what? You've not looked hard enough. This is something I say often enough, of course, so what's the point? The point is this: We still don't really think about this in network design. This shows up in many different places; it's worth taking a look at just a few. more

How Are ICANN’s New TLDs Doing?

ICANN has now accepted several hundred new top level domains (TLDs) and some of them are now open for general registration. I have sized up for zone file access, so I can download daily snapshots of most of the active zones, and I'm making daily counts of the number of names in each zone. more

Amplifying the Internet Governance Forum: Will the New IGF Leadership Panel Make the Difference?

On August 16, 2022, UN Secretary-General Antonio Guterres nominated ten high-level and eminent persons to serve in a new IGF Leadership Panel (ILP). The ILP includes luminaries like Vint Cerf, the father of the Internet, Tomas Hendrik Ilves, the former president of Estonia, and Maria Ressa, the Philippine woman who won the Nobel Peace Prize in 2021. It is an interesting mix of "usual suspects" and "fresh blood." more

Broadband Initiatives: Impact Will Depend on Wireless and Fixed Strategies

Broadband; we want it, and we all depend on it; but where you live can impact access and adoption of the best that service providers have to offer. The FCC is looking to change both geographic and demographic limitations now plaguing the U.S. in the global race for broadband economic supremacy. Can a combination of a fixed and wireless-mobile strategy improve broadband economic viability by increasing access, adoption, and affordability across the broadband spectrum? more

State-Sponsored Attack Is Manipulating DNS Systems of National Security Organizations

A team of security researchers on Wednesday issued a stern warning about a DNS Hijacking campaign being carried out by an advanced, state-sponsored actor believed to be targetting sensitive networks and systems. more

First Geographic NewgTLD, .RUHR, Now Delegated

Each week ICANN has been delegating more new generic top-level domains (newgTLDs) and it's been somewhat entertaining to watch the list of delegated strings to see what new TLDs will enter the domain name space starting sometime in early 2014 when they become generally available for people to register new domains under. more

ICANN Doubles Down on Technical Internet Governance Label: What Are the Implications?

Back in September of 2020, ICANN CEO Göran Marby wrote a blog post discussing the implementation of "a common strategy for Internet governance (IG) and technical Internet governance (TIG)", raising the question of whether the ICANN org. intended to pursue this distinction moving forward, as debated in a previous article. This was proven to be the case during the 2020 IGF's Open Forum #44: "ICANN Open Forum - Technical Internet Governance", organized by ICANN itself... more

World IPv6 Launch: This Time It Is For Real! - June 6, 2012

No more "test flights" ... 2012 is the year that IPv6 gets permanently deployed! That is the message of "World IPv6 Launch," announced today by the Internet Society, Google, Facebook, Cisco, Microsoft, Comcast, AT&T, Time Warner Cable and a whole host of other companies. While last year's successful World IPv6 Day was all about testing how your site or service worked with IPv6, this year's World IPv6 Launch is about enabling IPv6 permanently as of June 6, 2012 (or earlier). more
