In Praise of Relatively Dumb Pipes

Comcast's furtive and undisclosed traffic manipulation reminds me of a curious, red herring asserted by some incumbent carriers and their sponsored researchers: that without complete freedom to vertically and horizontally integrate the carriers would lose synergies, efficiencies and be relegated to operating "dumb pipes."... Constructing and operating the pipes instead of creating the stuff that traverses them gets a bad rap. It may not be sexy, but it probably has less risk. But of course with less risk comes less reward, and suddenly no one in the telecommunications business is content with that. So incumbent carriers assert that convergence and competitive necessity requires them to add "value" to the pipes. more

What Did we Learn Today About .XXX From IFFOR Tax Return

The 2011 Tax return for IFFOR has been filed and our friend George Kirikos of Leap.com found it.. IFFOR's tax return is important for two reasons. First IFFOR return shows us how how much money the non-profit, which is suppose to receive $10 for each .XXX registration, actually received from ICM the operator of the .XXX TLD and how IFFOR spent the money. Second the return is important to see how the money ICM the registry operator of the .XXX TLD paid to IFFOR matches up to ICM reported number of .XXX domain name registrations. more

IPv6: How Do the Top Ranked Tier-One ISP’s Perform?

A look at the world's dozen or so Tier one ISP's who run global networks and sell wholesale IP transit to national and regional 'tier two ISP's' is quite revealing when taking into account how their ranking evolved over the last five years. They peer with each other at selected locations while competing ferociously in an increasingly commoditized market. more

Why Restricted TLDs Should Not Be Gatecrashed

In recent weeks, thousands of what ICANN describes as "questionable" registrations have been activated... Let me illustrate: Mr. ICANN decides to hold a party. He has decided that he only wants to ask some of his professional friends to come, so they are asked to bring their party invites with them to prove they've been invited, because poor Mr. ICANN has had trouble before with people gatecrashing his parties. At a sunrise party he'd held a few years ago, all kinds of people had gatecrashed and no-one had asked to see their invites and it was dreadful. So Mr. ICANN hires a bouncer to stand guard at the front door of his house. The bouncer, Johnny Registry, assures Mr. ICANN that no-one will get in without an invite... more

What to Expect From SpaceX Starlink Broadband Service Next Year and Beyond

Last May, SpaceX founder Elon Musk tweeted "6 more launches of 60 sats needed for minor coverage, 12 for moderate" and SpaceX President and CEO Gwynne Shotwell recently said they planned to be offering service in parts of the US in mid-2020, which would require six to eight 60-satellite launches. The first of those launches will be in the middle of this month on a thrice-flown Falcon 9 booster. (They will also need customer terminals and Elon Musk has used a prototype to post a tweet from his home). more

Creating TLS: The Pioneering Role of Ruth Nelson

As often occurs in networking and cryptographic history, anecdotes and insularity conspire to mask how developments actually occurred, and seminal roles undertaken by women are forgotten or ignored. One of the notable examples of this proclivity occurred in the cybersecurity cryptology arena as it involves a critical platform known as the Transport Layer Security Protocol (TLS) and the pioneering role of Ruth Nelson. more

Comcast v. FCC - “Ancillary Jurisdiction” Has to Be Ancillary to Something

Big news today - Judge Tatel has written the D.C. Circuit's opinion in Comcast v. FCC, and Comcast wins. Bottom line: The FCC didn't have regulatory authority over Comcast's unreasonable network management practices because it failed to tie that authority to any express statutory delegation by Congress... more

The Real Issue About ICANN and .XXX

Way back in 2004, ICANN invited applications for a round of new TLDs. They got quite a few. Some were uncontroversial, such as .JOBS for the HR industry. Some were uncontroversial but took a long time, such as .POST which took five years of negotiation, entirely due to the legal peculiarities of the registry being part of the UN. But one was really controversial, .XXX. By 2005, the applicant, ICM registry, had satisfied all the criteria that ICANN set out in the 2004 round to get .XXX approved, and ICANN has been stalling them ever since... more

We Need You: Industry Collaboration to Improve Registration Data Services

For more than 30 years, the industry has used a service and protocol named WHOIS to access the data associated with domain name and internet address registration activities... The challenge with WHOIS is that it was designed for use at a time when the community of users and service operators was much smaller and there were fewer concerns about data privacy. more

Will Low-Earth Orbit Satellite Internet Service Providers Succeed?

In 1990, Teledesic was formed to deliver satellite-based Internet service. Cellular pioneer Craig McCaw, Microsoft co-founder Bill Gates and Saudi Prince Alwaleed bin Talal were early investors and Boeing was both an investor and the prime contractor. Teledesic hoped to offer global Internet connectivity using a constellation of 840 satellites in low-Earth orbit (LEO) at an altitude of 700 km... Teledesic failed. Twenty seven years later three companies SpaceX, OneWeb and Boeing are trying to do what Teledesic could not do. Will they succeed? more

Why 2008 Was a Milestone Year for IPv6

The beginning of the year saw IPv6 added to the DNS root, closing a major hole for IPv6-only communication. In mid-year, the US federal government's IPv6 mandate came into effect, requiring all federal IP backbones to support IPv6. While the mandate didn't have anywhere near the effect that many had hoped for, it did spur many vendors to add IPv6 support to their products. The amount of observed IPv6 traffic increased considerably, but we still lack good data for how much IPv6 is being used. So, where were we at the end of 2008? more

Using Whois to Enforce Law?

Before starting I'd like to remind you that there are two distinct Whois systems -- the one for IP address delegations and one for DNS registrations. I believe that the former is a useful system in which there are clear utility values that outweigh the privacy costs, and in which the person whose privacy is exposed has made a knowing choice. I do not believe that these arguments apply to the latter, the DNS, form of Whois. more

Pandora’s Box - New US Cyber Security Bills Create a Worm Hole in the Internet Galaxy

There are two Bills that are floating through the corridors of power on the Hill that could potentially change the course of civil and political rights within the United States and the world. One was introduced through the House of Representatives and the other through the Senate. The two Bills touch on a common thread that are premised on "national security" however there are interesting challenges that will surface should the Bills be passed that affect global public interest that require further examination, introspection and discussion. more

China Blocks Twitter, Flickr, Bing, Hotmail, Windows Live, etc. Ahead of Tiananmen 20th Anniversary

On Herdict, the global crowd-sourcing censorship-tracking website, people are reporting censorship of Twitter on networks all over China… with some people adding frustrated commentary, often including the f-word. You can also see blockage reports for Hotmail, Windows Live, Bing, Flickr, YouTube, Blogspot... more

Spam Volume Redux

Several anti-spam companies talk about spam volumes in terms of a percentage of all inbound mail. Outsourced anti-spam services such as BlackSpider and Postini are currently quoting spam volumes in the 70%-85% range, having steadily grown over the last two+ years. That's nice, but it's actually hard to grasp what that means in absolute terms. more
