If the Internet was the postal system, the only job of Internet Corporation for Assigned Names and Numbers (ICANN) would be to give each letter an address, the group's head insisted Monday.

Yet, ICANN President and CEO Paul Twomey realizes as much as anyone that the nonprofit group is being tugged to make decisions on issues as far-ranging as content and delivery.

VeriSign's recent lawsuit against the organization, accusing it of trying to regulate the company's controversial Wait Listing Service (WLS) for expired domain names, is just the latest example. VeriSign accused ICANN of overstepping its bounds as the Internet's technical coordinating body and delaying the implementation of its service amid protests that WLS is unfair to consumers by convincing them to back-order domain names they may never be able to register.

Under the group's charter, ICANN is only responsible for IP address allocation, protocol identifier assignment, the domain name system and root server management.

"What we do is narrow, and we don't need an added role," Twomey said during an interview in London Monday. The CEO had just wrapped up a group meeting in Rome over the weekend, where the organization had decided to allow VeriSign's WLS service to go ahead for a one-year trial period, with some stipulations.

Although the board approved of the service in principle, Twomey said he had not heard from VeriSign whether it would drop its lawsuit against ICANN. He also was not sure whether the organization would accept the $100,000 registrar Go Daddy Software pledged to help fund ICANN's defense in the case.

"Quite a number of people said they'd contribute, and we wouldn't say no since we are publicly funded... but there's no way we'd take money if it was tied to conditions," he said.

Twomey claims that "these issues are more than ICANN issues" and are a product of the contractual nature of its relationships with Internet registries.

"We have agreements with registries that they openly volunteer to enter and these disagreements are a product of these contracts," he said. "But what we are in charge of is actually very narrow."

If ICANN's function is narrow, it stands in contrast to Twomey's vision of what his organization and the Internet can actually do.
