Internet domain names using Cyrillic characters may start working this week after the world governing body for Internet domain names officially delegates the .рф domain to Russia. Representatives of the Internet Corporation for Assigned Names and Numbers, or ICANN, may officially assign the .рф domain suffix to Russia at the Internet Governance Forum, which begins on Thursday in Moscow, said Andrei Vorobyov, a spokesman for Ru-Center, a domain registrar. Once the .рф suffix, known as a top-level domain, is assigned, the Cyrillic domain names they have registered will become operational. ICANN in November approved the use of non-Latin characters in Internet domain names, clearing the way for domain names in Cyrillic and other national scripts. The first domain names using a non-Latin character set became operational last week, after web sites in Egypt, Saudi Arabia and the United Arab Emirates began using Arabic script in their web addresses.
