VeriSign and other registries are set to increase their wholesale price of domain names effective October 1, 2008.

The new .com price will be $6.86. With ICANN’s 20 cent fee that means the minimum cost to your registrar is $7.06. .Net prices will be $4.23 before ICANN’s fee.

Earlier today Domain Name Wire wrote about GoDaddy’s latest price increase on .net and .org domains, which have shot up about 30% to $13.19 including the ICANN fee.

Almost all of the registries are increasing prices, and eNom sent out a notice today that its prices will increase 50 cents effective September 30. You can expect other registrars to follow.

According to DomainWire the wholesale price of domains is increasing while domain registrations are ballooning. The growth of online advertising has been driving up the number of domain registrations and the explosive  growth of cloud computing services is expected to contribute to the growth as well. Most of the registry costs are fixed, and the cost to manage each incremental domain goes down as more are registered.

Registrars such as GoDaddy have complained that they’ll have to pass on the costs to customers haven fallen on deaf years. You can beat the price increase by renewing your domains before October. If you have domains you know you’ll hold onto for many years, go ahead and renew them at today’s rates for multiple years.
