Reserved domain names

The administrators of the .UA ccTLD have decided to reserve public domains with transliterations of Ukrainian names for most Ukrainian geographical domains. Geographical public domains, initially based on phone area codes, were allocated during a conference of Ukrainian internet specialists in Slavsko in January 1993, following the delegation of the .UA country code top-level domain. Initially, these domains were mostly transliterations of Russian city names (e.g., kiev.ua, kirovograd.ua, sebastopol.ua). As the Internet transitioned from experimental to mainstream technology, new requirements and discussions for alternative names emerged. In December 1997, shorter, easier-to-remember two-letter names were introduced (e.g., ivano-frankivsk.ua became if.ua). The introduction of these new names aimed to address inherent flaws without replacing old names, allowing parallel registration in both traditional and new domains. These changes, led by domain administrators Dmytro Kohmanyuk, Ihor Svyrydon, and Hostmaster LLC, will ensure Ukrainian transliterations are reserved and mirrored to existing geographical domains, available to administrators by autumn 2008, contingent on compliance with .UA domain rules. * .cr.ua:
