Neustar and Afilias Jump on the No-Tasting Bandwagon

In a message posted to the ICANN GNSO list, Avri Doria forwarded along a most interesting document from Neustar, who runs the .biz domain... Neustar proposes to change their registrar agreement so that each registrar will only get credit for deletions of 10% of their new domains, with a few minor exceptions for tiny registrars and bulk registrations due to one-time mistakes. They say they expect Afilias to propose the same change for .info.  more

As IPv6 Deploys, Will We Look Back on NAT as the Ugly Step Sister or Unsung Hero?

The debates are raging over whether or not we should migrate to IPv6. The strongest argument is the enormous address space that will allow for everyone and everything to have a unique public address, many addresses actually. It is often said that the shortage of public IPv4 addresses has limited our capabilities because it led to the pervasive use of private addressing, Network Address Translation (NAT) and Port Address Translation (PAT). Though these technologies remain critical, they are often regarded as stop-gap measures, and they sometimes create problems. In some circles, NAT has acquired a very bad name. But is that a fair perspective of the technology? Let's review the positives and negatives. more

If the Number ‘5’ License Plate is Worth $6.8 Million, What is Your Domain Name Worth?

The number "5" license plate sold for $6.8 million dollars in Saudi Arabia and another 300 vanity plates sold for another $56 million at last week's auction. It is estimated that the number "1" will be auctioned next month for up to $20 million dollars. Domain names and license plates share some common characteristics. Both allow only one person to own a particular word or number. Of course, the exact same license plate 'word' or 'number' can be registered in every country and, in the USA, every state... more

iPhone, Android, 700 MHz: What Maximizes Wireless Innovation?

At the Emerging Communications Conference eComm 2008, I'm moderating a panel "Wireless Innovation, with or without operators." This will be a discussion -- smart people from differing camps responding to (hopefully) probing questions from yours truly, and the audience. Points of view represented include Google Android, J2ME/JavaFX Mobile, iPhoneWebDev.com, Skype and Trolltech Qtopia (Nokia), plus Chris Sacca, formerly head of Google's wireless initiatives. I've been thinking about subjects and questions for the panel. As a start, I'll set down my current views, then seek others' views and questions. more

Microsoft’s Offer to Buy Yahoo: An Anti-Spam Point of View

Last Friday, Microsoft made an unsolicited offer to buy Yahoo for $31 per share, representing over a 50% premium from Yahoo's then-share price. As an employee working for Microsoft in Exchange Hosted Services (i.e. spam filtering), I'd like to comment on this buyout offer. Leaving aside the question of whether or not this is a good deal for shareholders and what Microsoft's true motivations are for buying Yahoo (namely, to become the number 2 player in the search market), I'd like to look at it from an anti-spam point of view. more

The Internet’s Weakest Link

This week two major transoceanic cables experienced outages that may last several days. The outages provide a reminder that several Internet bottlenecks exist where these cables make landfall. When one thinks of bottlenecks in telecommunications the first and last mile come to mind. Yet equally vulnerable are the last few 1000 feet of submarine cable links. more

Internet Repotting About to Start!

February 4th 2008 will be the day the repotting of the internet finally starts. A milestone of sorts for some people who spent a good part of the last five years getting us this far. It should now be finally possible for a IPv6 only device to have a chance to communicate on the Internet. Indeed, today, IPv6 address information is not included in most root DNS servers. Some good write-ups are already appearing on the subject covering the relevance of this development... Why get excited as there are practically no IPv6 only devices yet, some will bemoan. Well, one can hear a distant rumbling of such devices coming, alongside the mobile internet... more

Is China Preparing to Go its Own Way with its Own Internet Root?

Interesting things happening in China. An article in the English edition of the People's Daily on line is headlined, Decimal network security address begins operation: "China's decimal network security address was officially launched. China has made a fundamental breakthrough in its Internet development; and actual use has been successful. The birth of decimal network technology makes China the only country able to unify domain names, IP addresses and MAC addresses into the text of a metric system..." Someone asked whether this was a rumored IPv9? It appears IPv9 is a project name, not a new protocol. It lumps together several activities, including at least... more

More on 700 MHz Block C Hits Reserve Price

This is big... For the upper band C Block, the FCC mandated that any winning licensee have in place "no locking" and "no blocking" provisions conditioning its use of this spectrum: "Licensees offering service on spectrum subject to this section shall not deny, limit, or restrict the ability of their customers to use the devices and applications of their choice on the licensee..." The no-locking, no-blocking requirements were hedged in by substantial limitations... But it's still important... Particularly if Google is the winning bidder, something we may not know for a month or so. more

Domain Tasting to Go Away for Real This Time

At last week's meeting, the ICANN board uncharacteristially did something and voted to make their fee of 20 cents per domain-year nonrefundable. They expect this to stop both domain tasting and NSI's frontrunning, which it certainly will. It's not clear when this change will go into effect, but it might be within a month. more

2008 Report Analyzing Distribution and Trends of IP Address Allocation

The study report analyzes the distribution and the trends of IP address allocation in 238 countries for 2007. From the data analysis (see Table 1 & Chart 1), the United States tops the allocation list by holding 37.73% of the IP addresses worldwide. It follows by United Kingdom (12.83%), Japan (7.64%), China (5.74%), Germany (3.81%), France (3.65%), Canada (2.81%), Korea (2.74%), Netherlands (2.00%) and Italy (1.67%). These Top 11 countries in the list occupied more than 80% of total allocated IP address ranges in the world in 2007. more

Facebook Apps on Any Website: A Clever Move? Or a Security Nightmare?

Well, given the amount of malicious JavaScript, malware, and other possibilities to use Facebook (and other similar social networking platforms) for abuse, I certainly wouldn't categorize this news as a "clever move"... In fact, I foresee this as an extraordinarily short-sighted move with far-reaching security implications -- which will allow the levels of malicious abuse to reach new heights. more

Are Domain Names Recession-Proof? Probably Not, Next Question?

I didn't see the Fortune article Are domain names recession proof until the weekend, and being the author of the now infamous Domain aftermarket overdue for an asset repricing last year I feel somewhat obligated to comment on it. So, how will domain names fare in a recession? The Fortune article was upbeat... more

Client-based WDS: Providing Application Acceleration in Mobile and VPN Environments

Wide-Area Data Services (WDS), aka "WAN Optimization" is becoming the most effective way to improve application performance while reducing network traffic. In scenarios where there is significant network latency that would otherwise render many applications unusable, WDS can deliver almost LAN-like speed. Where bandwidth constraints exist and there is no practical or economical option, WDS can help reduce network traffic, allowing you to postpone or avoid circuit upgrades altogether. The technology provides the ability to centralize applications and servers, furthering the cost savings on hardware, software licensing, maintenance and the operation of a distributed architecture. more

How Tiered Internet Pricing Could Actually Facilitate P2P

Time Warner Cable's planned experiment with tiered charging for Internet access has generated a flurry of coverage in the blogsphere, but no new insights (at least that I've seen). The primary problem ISP's complain about is that 5% of their customers use 90% of the available bandwidth and when they examine this traffic, it's mostly peer-to-peer file sharing... more
