Moving Telephone Numbers Into the Internet Age

Now that we're 20 years past TN 2.0, well into the 21st century, and onto the 3rd generation of the web; it is about time we move telephone numbers into the Internet age. They are still managed as if they all connect to four copper wires. We manage to the lowest common denominator rather than acknowledging the power of mobility and Internet technology. more»

Success Drivers of New gTLD Applications

Being approved by the Internet Corporation for Assigned Names and Numbers (ICANN) as the owner of a new generic top-level domain (gTLD) extension requires considerable analysis before the application is submitted. You must understand the sources of risk, gauge your risk tolerance, and you must obtain an estimate of the value of your proposed TLD's future revenues (with the effects of potential competitors factored in, a step too many applicants ignore). more»

Domain Dialing

The emergence of generic Top-Level Domains (gTLDs) and country code Top-Level Domains (ccTLDs) allowed the internet browsing to become much easier and intuitive. After all, from the user's perspective, it is so much easier to remember a domain instead of an IP address... The IP addresses replacement by domain names helps the Internet to become this global phenomenon that we know. Unfortunately, this revolution that had occurred in the domain market was not followed by other markets. more»

Could .NAME be the Killer App ENUM is Waiting For?

I'm in the camp that ICANN Top-Level Domains (TLDs) are businesses that should be allowed to evolve from their original charter to increase their viability in the marketplace. It was announced today that VeriSign is proposing to allow telephone numbers and other numeric identifiers in the .NAME top-level domain. This could be the Killer App that ENUM has been waiting for. more»

VIPR: New Developments in the VoIP Market

This is a new development in the VoIP market. This is how one of my colleagues, Cullen Jennings explained it to me. Today we have two widely deployed global identifiers for reaching people. One is delegated address out of DNS and the other is phone numbers. So I consider an address like email: carol@johnson.com or xmpp:john@gmail.com to roughly be out of the DNS namespace and phone number to be out of the E.164 name space. Phone numbers have lots of parts that are not cool, but they also have some cool parts... more»

Google Voice Dispute Highlights an Opportunity for Mobile Network Operators

The recent row between Google, Apple and AT&T concerning the removal of Google Voice from the Apple iPhone store highlights the friction existing between network operators and so-called over the top (OTT) application providers. Most observers believe that AT&T initiated the blockade because Google Voice (which offers free or highly discounted calling rates) is a direct threat to AT&Ts call revenue (Google Voice users need only pay AT&T for access to the Internet). more»

Will ENUM Deliver?

ENUM (E.164 NUmber Mapping) is a technology that has been around for a little while that has promised much and, so far, delivered little to the average user. As Nominet has recently been awarded the contract to administer the UK 4.4.e164.arpa delegation, I thought it was time that I put my thoughts on this subject down in writing. I'm going to cover the potential of ENUM in the telecoms industry and what it could mean to you, along with how it is currently being used and what potential security issues surround ENUM. more»

Call for Telecom Industry Wake-Up

As many of you know, I'm launching the Emerging Communications (eComm) conference -- taking place next month in Silicon Valley, at the Computer History Museum. Communications innovation has been stagnant, in my opinion, for nearly a decade. Telecommunications and Internet communications both seem to be at somewhat of an impasse. The communications industry needs a forum to help break through the stagnancy and highlight the huge opportunity space that is emerging. The stagnancy has been strikingly more so in telecommunications... more»

DNSSEC: Once More, With Feeling!

After looking at the state of DNSSEC in some detail a little over a year ago in 2006, I've been intending to come back to DNSSEC to see if anything has changed, for better or worse, in the intervening period... To recap, DNSSEC is an approach to adding some "security" into the DNS. The underlying motivation here is that the DNS represents a rather obvious gaping hole in the overall security picture of the Internet, although it is by no means the only rather significant vulnerability in the entire system. One of the more effective methods of a convert attack in this space is to attack at the level of the DNS by inserting fake responses in place of the actual DNS response. more»

FreeNum Links Phone Numbers to the Internet

I loved John Todd's ETel presentation (podcast) on FreeNum, a scheme for bringing phone numbers to the Internet. Of course, I love identifiers and addresses and all that they enable, so it was a natural. Suppose you were a university campus and when you looked at your phone bill, you noticed that a lot of calls were to other universities. You've got a VoIP telephone system; they've all got VoIP telephone systems. You might wonder "isn't there some way to route these calls over the Internet and save some serious money?" The answer, of course is "yes" but making it usable is a little harder... more»
