.ua is the Internet country code top-level domain (ccTLD) for Ukraine. To register at the second-level (example) domainname.ua, possession of the exact trademark (matching the domain name) is required. It is not required for third-level domains (.com.ua, .net.ua, etc.).

History

  • 1 December 1992: Registered in root zone
  • 13 April 2012: DNSSEC enabled in root zone
  • 26 February 2022: Domain servers transferred out of Kyiv for continuity reasons amid the 2022 Russian invasion of Ukraine[2]

Statistics

As of March 2017, around 10.78% of all the .ua domains were served via secured HTTPS protocol, with the Let's Encrypt Authority X3 being the most popular SSL certificate.[3] Nginx is the most popular web server, serving 68.97% of the .ua domains, followed by Apache serving 17.75% of the total .ua domains.[3]

Third-level & second-level domains

To remove the risk of cyber squatting, registration of second-level domains directly below .ua is restricted to owners of registered trade marks, who may register a domain name similar to that of the trade mark in question. However, third-level domains can be registered beneath some of the following:

  • .com.ua: paid, commercial organizations
  • .edu.ua: free, available only to proved educational organisations.
  • .gov.ua: free, available only to governmental organizations
  • .net.ua: paid, network service providers
  • .in.ua: paid, domains for individuals
  • .org.ua: paid, other organizations (non-commercial)
  • .mil.ua: free, available only to armed forces
  • .dod.ua

There are also second-level domains which are region-specific. These are less popular than the above list (making domain names more available) but they are sometimes restricted to organisations exclusively from within the region.
