However, the US Department of Commerce has final approval of any price rises to renew .com net addresses.
Verisign and the Internet Corporation negotiated the original deal over the .com domain for Assigned Names and Numbers (Icann), which oversees the net's address infrastructure.
Details of the deal were given to the US Department of Commerce in March 2006.
Verisign has run the .com domain since 1999 and now has the right to keep on controlling it until 2012 and the right to raise prices to renew .com domains in four of the six years of the contract.
The .com domain is without a doubt the most popular of the net's addresses and currently there are 59 million domains registered which use the suffix. Verisign oversees the address books of who owns which .com domain and is in charge of computers that direct web users' computers to the right place.
