Must be the owner of a trade mark registered in Ukraine for second-level domains (and may only register if the domain name is the same as the trade mark); no restrictions for third-level domains
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
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.
