ICANN considering cybersquatting block

The Internet Corporation for Assigned Names and Numbers (ICANN) is considering a centralized database of trademark holders, to cut down on questionable registrations of new Internet addresses. Backers of the idea say it is needed so trademark holders won't have to spend thousands of dollars registering domain names defensively, to block someone from registering them and trying to profit -- a practice known as "cybersquatting." The proposed trademark database comes as ICANN is trying to widely expand the number of Internet domains, which include ".com," for the first time since the 1980s. New names could start appearing next year.
