It has been established that there are over 55, 000 .iran and .ir domains registered in Iran says an official in charge of .ir registrations at Theoretical Physics and Mathematics Research Center.

Siavash Mir-Shashahani added "Out of that total, 2030 domains are .iran and the rest are .ir domains. Welcome rendered to .iran domain is still not as high as expected, because the Iranians are still entangled with problems regarding website in Persian language, because the keyboards of their computers are often merely offering the English alphabet, and so are the operating systems with which they work. The applicants can add a .iran suffix to their .ir Domain Name, so that they would not have to change their keyboards to one with Persian alphabet either."

Although official registration for .iran domains started September 2005, using Persian language domains have privileges users, (for instance there are no standards in Persian language for turning a Persian name into a Latin language, such as English, French, or German, but using a Persian domain prefix can solve the problem).
