Cerf, Dyson Voice Concerns About Domain Expansion

Two key former officials with the nonprofit group that manages the Internet's domain name system are raising concerns with its plan to allow an unlimited number of generic Internet addresses, the top-level domain name suffixes that come after the dot like .com or .org. Google Chief Internet Evangelist Vint Cerf and tech investor Esther Dyson -- who chaired the Internet Corporation for Assigned Names and Numbers during its early years -- now said they see several potential problems with ICANN's latest domain name plan, which has sparked strong opposition from major trademark owners.
