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.[2] 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.[2]
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 you can register third-level domains beneath some of the following:
.mw-parser-output .monospacedfont-family:monospace,monospace
- com.ua - paid, commercial organizations, one of the most popular
- 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
- pp.ua - free, domains for individuals
- org.ua - paid, other organizations (non-commercial), individuals
