I wrote a column for Muscat Daily a while ago on the new arbitrary restrictions imposed on the registration of Omani (.om) domain names, but after I wrote this column I discovered that these restrictions are not completely arbitrary as the TRA has specified in the Omani Domain Name Regulations of 2012 a list of categories of prohibited domain names that may not be registered in Oman on technical, legal, moral, or social grounds. Even though this list has been around since 2012, I do not believe that it was actually enforced in the same way it is done now because I was able to register my domain name (riyadh.om) in 2015 without any issues. According to the Omani Domain Name Regulations, my domain name falls under a prohibited category because it also happens to be the name of a geographical location, and the registration of the names of capital cities is now not possible through any of the accredited registrars (such as Omantel). For example, amman.om, cairo.om, and doha.om are all unavailable for registration, not because someone has already registered them, but because they are restricted names. This can be verified using the .om WHOIS service.
