What's in a domain name?
The Washington Post headline sounded alarming: "Network Solutions Dropped as Registrar of Internet Domains." If the small company in Virginia that currently hands out domain names has been "dropped," who will pick up the ball? Will domain-name chaos ensue?
The story, it turned out, was not nearly so precipitous or calamitous: What happened was that the National Science Foundation, which gave Network Solutions a contract to run the domain-name business through April 1998, announced that it was not renewing the old contract -- and not giving out any new ones.
On the eve of an international conference in Geneva to deliberate over domain-name service (DNS) authority, the NSF announcement was less a bombshell than a confirmation of an already existing state of near-anarchy. Players in this free-for-all include Network Solutions (which claims full authority over the widely used and coveted .com domains), the International Ad Hoc Committee (IAHC, which has proposed seven new top-level domains like ".firm" and ".store" and a lottery to add 28 independent registries for them), international telecommunications boards, private Net businesses and, of course, the U.S. government.
The conflict among these groups is important but dense, a bureaucratic and technical swamp full of numbing acronyms. Behind it may lie another and potentially more ominous story that doesn't seem to be getting much attention.
According to Gordon Cook, editor and publisher of the Cook Report newsletter, the DNS battle is far less important than a less-well-publicized but more technologically central conflict looming over IP number assignment. IP numbers -- the 12 digits that identify every computer on the Net -- are the Internet's real addresses; domain names are just aliases or pointers that sit in front of the numbers and make the Net a (little) bit easier to navigate. If Cook is right, we should be seeing a lot fewer headlines about domain names and a lot more about the less sexy but more fundamental IP numbers.
Today, the final authority for IP number assignment resides with an obscure body known as the Internet Assigned Number Authority (IANA), which operates out of the Information Sciences Institute (ISI) at the University of Southern California and is run by Jon Postel, a computer scientist who was one of the Net's pioneers. But Cook says that IANA and Postel have been left vulnerable in the current environment of bureaucratic infighting and legal jockeying.
Postel's and IANA's authority derives from custom and from a contract between DARPA, the Federal agency that funded the Internet's early development, and the ISI. Cook says that since that contract expired on April 1 and was not renewed, IANA is vulnerable to the first bad court decision to come down the pike.
Here's his nightmare scenario: Say a lawsuit gets brought against Postel or IANA by a company that wants to run its own set of domain names or IP numbers, in competition with the existing authorities. Say the suit comes before a judge who's not particularly friendly to Internet tradition or educated in Internet technology.
Asks Cook: "What's gonna happen when a judge says, 'I don't see any legal authority for Postel to do what he's doing. I mean, "The consensual authority of the Internet community"? I beg your pardon, what's that?'" The result could be chaos: "If anybody can put anything in the root servers, then domain name service will eventually break."
What does this mean in practical terms to the average user? If domain name service "breaks," every Web address you type in your browser, every bookmark and every link would give you the same error message: "Unable to locate the server. The server does not have a DNS entry." Every e-mail you send would be returned to you as undeliverable. The Net as we know it would crash.
IANA is "the linchpin of the Internet," in Cook's words, and it's "floating on air" right now. Disaster, it turns out, may be almost as imminent as the Washington Post suggested -- but for very different reasons than the paper reported.
