Operators of the ".travel" domain name are proposing a new search service to help guide people who mistype Web addresses or seek nonexistent ones, reviving a debate over how much control such organizations should have in directing Internet traffic.

One review panel already has recommended that the Internet Corporation for Assigned Names and Numbers reject Tralliance Corp.'s proposal for "search.travel," saying it appears no different from the Site Finder service that VeriSign Inc. had introduced for ".com" and ".net" and withdrew under pressure.

But unlike Site Finder, which also drew complaints that a company was trying to profit off the popularity of ".com," the concerns with ".travel" are strictly technical.

Tralliance argues that there are far fewer ".travel" sites -- about 20,000 compared with some 56 million for ".com" -- and thus they are less central to the Internet's infrastructure.
