Demand for Internet addresses continues to grow in 2010, though it's not uniform across all Top Level Domains (TLD).

According to a new report from VeriSign, the first quarter closed with a total of more than 193 million registered domain names. The Q1 tally represents an increase of 6 percent, or 11 million domain names, over the first quarter of 2009.

A year ago, the .cn county code Top Level Domain (ccTLD) for China was gaining fast and looked like it might overtake .com. In 2010, that's not quite the case, as overall demand for ccTLD registrations slowed, and VeriSign is reporting that .cn was actually on the decline.

According to VeriSign's report, the first quarter saw .cn slip from second place behind only .com to fourth place. In descending order, VeriSign's top 10 list of TLDs in the first quarter was: .com, .de, .net, .cn, uk, .org, .info, .nl, .eu and .ru.

The firm explained the decline in the .cn domain as a byproduct of new policies to help ensure that domains are legitimate.

"Many of these are low-priced promotional names that have now come up for renewal at a higher price," Pat Kane, vice president of naming services at VeriSign, told InternetNews.com. "The .cn registration decline was also based on the CNNIC (China Internet Network Information Center) registry's implementation of the real names directive from the Chinese government primarily around verifiable 'whois' data."

While .cn registrations declined, VeriSign reported that .com and .net registration hit 99.3 million names in the first quarter, an increase of 7 percent on a year-over-year basis. The first quarter of 2010 also marked a significant milestone for .com as the domain celebrated its 25th anniversary.

".com has been a platform for Internet innovation over the past 25 years, and we expect .com will continue to play a central role for the innovators, entrepreneurs and companies who will shape the Internet over the next 25 years," Kane said.
