A plan to dramatically expand the number of possible Web addresses — by adding more than 1,000 new domains such as “.buy,” “.casino” and “.gay” — could cause widespread disruption to Internet operations, say some industry officials.ICANN's Domain Expansion Criticised, and May Cause "Collisions" [washingtonpost.com] Particularly troubling is the possibility of widespread “name collisions” that could happen when domains used by internal corporate computer systems — such as “.corp” or “.home” — get assigned to the Web more broadly. This could cause systems to fail, blocking access to e-mail or other internal programs, and also could open sensitive information to theft, some experts say.
“This could affect a million enterprises,” said Danny McPherson, chief security officer for Verisign, which is based in Reston and manages several of the most popular existing domains. “It could absolutely break things.”
Among those posing risk could be domains such as “.med” or “.center” that might be critical to the functioning of medical systems or emergency-response networks.
