Centralizing the Net, Monetizing DNS, Getting Trendy?

In a Red Herring Conference held last week in California, Mitch Ratcliffe's offers an analytical overview of an interview held with Stratton Scalovs, VerisSign's CEO..."He then goes on to say that we need to move the complexity back into the center of the Net! He says the edge can't be so complex. Get David Isenberg in here! Ross Mayfield, sitting in front of me, laughs out loud. I am dumbfounded. According to VeriSign, the Net should not be open to any type of application, only applications that rely on single providers of services, like VeriSign. This is troglodyte talk." more

NAT: Just Say No

Fueled by the lack of public IP addresses, 70% of Fortune 1000 companies have been forced to deploy NATs (Source: Center for Next Generation Internet). NATs are also found in hundreds of thousands of small business and home networks where several hosts must share a single IP address. It has been so successful in slowing the depletion of IPv4 addresses that many have questioned the need for IPv6 in the near future. However, such conclusions ignore the fact that a strategy based on avoiding a crisis can never provide the long-term benefits that solving the underlying problems that precipitated the crisis offers. more

Convergence: ENUM is a Big Deal

Convergence as a technology concept has been around for decades. Many have predicted the convergence of electronics and entertainment, of PC's and TV's, and more recently of WiFi and cellular. All of these areas are in fact undergoing various degrees of convergence but there is another area that many are not as familiar with. It is called ENUM...The idea can be extremely useful when you consider that most telephones are limited to twelve keys on a keypad. Ever tried to enter your alphanumeric login ID and password to a web site on a cell phone or Personal Digital Assistant? It is next to impossible! The biggest impact of ENUM will probably be for Voice Over IP (VoIP). In fact, it could be the tipping point. ENUM is a really big deal. more

SECSAC Special Meeting on Site Finder: A Technical Analysis

After attending the afternoon ICANN Security & Stability Committee meeting, I realized that the issues involved fall into several related but independent dimensions. Shy person that I am *Cough*, I have opinions in all, but I think it's worthwhile simply to be able to explain the Big Picture to media and other folks that aren't immersed in our field. In these notes, I'm trying to maintain neutrality about the issues. I do have strong opinions about most, but I'll post those separately, often dealing with one issue at a time. more

Online Registries: The DNS and Beyond

As the world grows more connected and more complicated, we all need ways of defining, identifying and keeping track of things and cross-referencing them with their owners. The simplest way to do that is with registries -- everything from the Domesday Book, a medieval registry of land, property and people; to current-day auto registries on the one hand and the worldwide Domain Name System on the other...But now, companies and organizations have to keep track of ever more things and people, not just inside their walls but across extended organizational boundaries. Call this new wrinkle an "external registry". Finally, they may want to interact with things and people, rather than just look them up, via an "active registry".  more

Parsing Hype From Hope: Will ENUM Spark Changes In Telecom?

In the beginning there was silence; then, silence begat communication, and communication begat more communication and, ultimately, group communication formed and begat a primordial "network" of communication that gradually and inevitably increased in effectiveness and complexity: there were only signal fires at first but, then, there were cave drawings, carrier pigeons, shouting from hill-tops, smoke from fire, lines of cannon fire, the telegraph, Alexander Graham Bell, and, finally, the network of networks known as the Internet. But, is that it? Is there not something more impressive in its impact upon communication than the Internet? What more might one desire than the dynamic wonders of the Internet, you ask? Well, what about ENUM? "E-What!?" more
