Ottawa Committed to Overturn CRTC Decision on Usage-Based Internet Billing

Canadian Industry Minister Tony Clement has announced that the Harper government will overturn the CRTC's decision that effectively ends "unlimited use" Internet plans if the regulator doesn't rescind the decision itself. more

Is the Web a “Communications Medium”?

I've been having a short Twitter exchange with Paul Downey (@psd), someone who I hold in high intellectual and personal regard. I've made an assertion that has Paul snorting his coffee back up through his nose and into his keyboard: that the Web is not a communications medium. Justifying this claim can't be done in 140 characters. Now, there is a sleight of hand I'm pulling off here. You can build communications media on the Web, but my claim is that the Web itself is not one, and that has subtle but significant consequences. more

Proxy-Privacy User Higher for Illicit Domains

WHOIS issues are looming large for the ICANN meeting next week, starting with an all-day WHOIS Policy Review on Sunday (background). WHOIS is a subject that has been the recent topic of a number of issues including a debacle over potentially disclosing the identities of compliance reporters to spammers and criminal domainers. more

Inquiring About the “Unthinkable”

There has been no shortage of speculation within the ICANN community regarding the continued show down between the ICANN Board and its Governmental Advisory Committee (GAC) over new generic Top-Level Domains (gTLDs) and the pending expiration of the IANA contract this September. Now one of the more interesting topics of discussion that I have had with multiple independent parties was the potential of ICANN making changes to the L root zone file... more

International Internet Governance: A Field Guide to 2011

If an important debate of our age is going on right now but you don't know where, no one can blame you. Part of the intrigue surrounding discussion of how the Internet will be governed is deliberate; the current process and forums were conceived by parties who want to make sure that if their agenda fails in one place that they can claw back ground in another. Part of that plan is the byzantine "commitology" of the UN system, which is now frighteningly relevant to the broadband industry and civil society. What follows is an effort to make this clear what, where, when, and how it all will happen in 2011. more

Domain Pulse 2011: New gTLDs, Their Impact on Aftermarket and Importance of Domain Names

The impact of new generic Top-Level Domains on the price of existing gTLDs and ccTLDs is likely to be limited, Tim Schumacher, CEO of leading domain name marketplace Sedo, told the the Domain Pulse conference in Vienna, held on 17 and 18 February. "I don't think the new gTLDs will have a major impact on pricing of existing TLDs. If you start a company or a product, you will always need to have your 'dotcom' or respective ccTLD in the market you operate in," said Schumacher in an interview following the conference. more

URL Shorteners

If you're a twit a Twitter user, you've likely used one or another of the URL shorteners out there. Even if you're not, you may have run across a shortened URL. The first one I encountered, several years ago, was tinyurl.com, but there plenty of them, including bit.ly, tr.im, qoiob.com, tinyarrow.ws, tweak, and many others. ... What would best practices for URL shortening services look like? Some suggestions, from others as well as from me. more

IP Blocklists, Email, and IPv6

Engineers in the Internet Engineering Task Force, in the Messaging Anti-Abuse Working Group, and elsewhere have been debating how to handle e-mail-server blocklists in an IPv6 network. Let's take a look at the problem here. We basically have three ways to address spam, in our goal of reducing the amount of spam in our inboxes... more

ICANN’s New gTLD Double Standard?

Over the last two days I have sat in a room and watched a rather interesting dynamic unfold between the ICANN Board and its Government Advisory Committee (GAC). While I remain optimistic of there being a responsible closure to the new gTLD implementation process within the next six months, an apparent double standard being used by the ICANN Board could be a potential stumbling block. more

ICANN Board: You Got It Right. Then You Got It Wrong. Now, Get It Right Again.

The ICANN Board has itself in a pretty pickle. The Governmental Advisory Committee (GAC) Consultancy with the Board in Brussels was an apparent non-starter. After hundreds of man-hours' worth of comments provided by the Intellectual Property Constituency (IPC), the Board continues to claim that it lacks sufficient information on trademark issues in order to respond to concerns. more

Comcast’s Impressive System for Notifying Infected Users

Pretty much as long as there've been computers, one of the biggest challenges has been user education. How do you create software smart enough to inform a user when they're about to do something potentially disastrous - or, worse, when something disastrous has been done to them? As one of the world's largest access providers, Comcast has put a ton of thought into developing a notification system for their users. The solution Comcast developed involves, in effect, hijacking HTTP requests... more

Blacklist Operations and Practices: Excerpts from an ASRG Draft

The Anti-Spam Research Group (ASRG) published a draft for an Overview of Email DNSBL Best Practices. We can take a step back and review paragraph 2.2.5 (Conflict of Interest)... Some DNSBLs used for blocking/negative reputation have had a practice of requiring fees or donations to charities from the listee for delisting. It is generally considered entirely appropriate for a DNSBL to charge for access to it by its users -- the definition of a commercial DNSBL. more

NTIA Request for Comments on the Internet Assigned Numbers Authority (IANA) Functions

On Feb. 25, 2011, the National Telecommunications and Information Administration released the following request for comments concerning the USG's contract for the IANA function. As indicated, the USG's contract for the IANA function with ICANN expires later this year. Interested parties can file comments with NTIA by March 31, 2011. more

Whois Scared?

Every time I witness another argument about changing the rules of the Whois system I marvel at how such an important core internet protocol could be so widely misunderstood. I don't mean that the protocol's technical details are not well understood -- it's a very simple device, easy to implement correctly and easy to use even for new users. I mean that the Whois system itself and its purpose in the Internet ecosystem is widely misunderstood. Everybody uses Whois and lots of people argue about Whois but precious few folks know why Whois exists in the first place. more

Caidagram: Visualising Geographically Annotated Internet Measurements

With measurement networks rapidly evolving up to hundreds of nodes, it becomes more and more challenging to extract useful visualisations from tons of collected data. At the same time, geographical information related to Internet measurements (either known or inferred with state-of-the-art techniques) can be exploited to build tools based on geography as a common knowledge base. We wanted to develop a tool to visualise different classes of geographically annotated Internet data, e.g., topology, address allocation, DNS and economical data. more
