Managing Internet as a Shared Resource: Reasonable Technical Constraints?

The internet is a shared resource. Different access providers begin mixing traffic at different places, but sooner or later, my internet gets mixed into yours. The Canadian Association of Internet Providers (CAIP) application to the Canadian Radio-television and
Telecommunications Commission (CRTC) seems to acknowledge this shared nature with its reference (at paragraph 50 of its application) to the description of the Gateway Access Service its members resell, a description complete with a graphic of a cloud -- a sign that the resource is being shared... more

Goo Goo Goggles: 700MHz Spectrum Auction and the U.S. Taxpayers

Scott Cleland claims the open access rules on 700MHz spectrum triggered by Google's bid fleeced the US taxpayer by $7bn. I don't buy it, even as a signed-up fully-paid network neutrality opponent. Firstly, the numbers ignore economics. If the C block was encumbered, that would raise the prices of the A and B blocks. So you need to take a much smaller differential as to the cost of the encumbrance. more

Whose Network Is It?

A reader sent me a link last week to a piece that doesn't speak highly of net neutrality. Clyde Wayne Crews wrote an article called "Dumb Pipes, a Dumb Idea: Net Neutrality as 21st Century Socialism" that calls for legislators to reject "nut" neutrality. "Elevating the principle of mandatory net neutrality above the principle of investor ownership and wealth creation in pipes and spectrum deflects market forces away from the infrastructure development that we need..." Did anyone else see a touch of irony in a letter to the editor... more

Sender Address Verification: Still a Bad Idea

A lot of spam uses fake return addresses. So back around 2000 it occurred to someone that if there were a way to validate the return addresses in mail, they could reject the stuff with bad return addresses. A straightforward way to do that is a callout, doing a partial mail transaction to see if the putative sender's mail server accepts mail to that address. This approach was popular for a few years, but due to its combination of ineffectiveness and abusiveness, it's now used only by small mail systems whose managers don't know any better. What's wrong with it? more

Cisco Speaks at FOSE on IPv6 Enterprise Architecture Transition

"The world is flattening," says Dave Rubal at the FOSE Conference and Exhibition this week in Washington, DC. "The race for IT dominance is on, and it is coming west." Mr. Rubal, Cisco's Worldwide Internet Protocol version 6 (IPv6) Task Force Lead, spoke of the tremendous race in IT dominance that is occurring, stating that the "mainstay technologies at the Beijing Olympics will be IPv6-powered." IPv6 is in line to replace version 4, but Rubal hinted that China and other Far East countries may be adopting the new version faster than the United States... more

Are Domain Name Registrars Ready for IPv6?

Now that ICANN has added IPv6 name servers for the root zone, and that many registries have enabled IPv6 on their DNS servers, I thought it would have been easy to update the DNS records pointing to my domain to mention a IPv6-only DNS server. This way, we could have native name resolution end-to-end in IPv6. We are not there yet, it seems. more

New Publication on Updating the Anti-Cybersquatting Regime and Ad-Based Cybersquatting

Sealing the cracks: a proposal to update the anti-cybersquatting regime to combat advertising-based cybersquatting is the title of an article by Christopher Varas in the April issue of the Journal of Intellectual Property Law & Practice. In this article, the author labels "modern cybersquatting" the monetization of domain names through PPC advertisements, and says that brand owners lack effective tools to combat this practice... more

Domain Name Price Jump: Moore’s Law or Parkinson’s Laws?

As expected, VeriSign raised the price of domain names, effective in October. New prices wholesale prices (to the registrar) for .com domain names are going from $6.42 to $6.86, while .net will increase from $3.85 to $4.23. This news came a few days ago in a letter to registrars. (Hint to consumers: renew your domains now.) ...So, basically, many if not most of VeriSign's registry costs have been falling at an exponential rate. Hard disk storage, computing performance, bandwidth, RAM storage... yet the cost is going up. How is this justified? more

An Open Letter to Yahoo!‘s Postmaster

In June 2004, Yahoo! and a number of other companies got together to announce the Anti-Spam Technical Alliance or ASTA. While it appears to have been largely silent since then, ASTA did at least publish an initial set of best practices the widespread adoption of which could possibly have had some impact on spam... The majority of these are clearly aimed at ISPs and end users, but some are either generally or specifically relevant to email providers such as Yahoo!, Google or Microsoft... The problem: Since February this year, we have been receiving a significant quantity of spam emails from Yahoo!'s servers. In addition to their transport via the Yahoo! network, all originate from email addresses in yahoo.com, yahoo.co.uk and one or two other Yahoo! domains. Every such message bears a Yahoo! DomainKeys signature... more

Trust in Email Begins with Authentication

As most CAUCE supporters already know, forging 'From:' or other commonly seen email headers is trivially easy. It's one of the most frustrating oversights in the creation of Internet email technology -- though of course that's only obvious in hindsight; it was just fine for the pre-Internet networks of the late 1970s and early-mid 1980s. Since then, things have changed -- and the most interesting recent technological advancements in email have been in the realm of sender authentication, which encompasses ways to verify that the apparent sender of a message actually is the entity which sent it. more
