NetNames Inc, the domain name registrar that registers names in most of the country-code domains as well as .com, .net and .org, will later this quarter launch version 3.0 of its Search & Alert service that enables users to be alerted to any domain names that become available according to a search string that they choose. Jan Kallberg, NetNames director of intellectual property services, reckons that due to the explosion in domain name registration in the second half of 1996 through early 1997, there is likely to be between 250,000 and 400,000 names returned to the market by people and companies that do not renew their two-year subscriptions. At present Search & Alert costs $365 per search string or $1,450 for five and the new service will be added for no additional cost. NetNames, which gets 80% of its business from the corporate market, also offers access to 60 attorneys around the world who are experts in local trademark and intellectual property law.
