Punycode Converter (Domain)
Convert domain names between Cyrillic (.рф) and Punycode (xn--) format
About this tool
Convert domain names between Cyrillic (like .рф) and Punycode (xn--) format. DNS only supports ASCII, so international domains are encoded as Punycode behind the scenes.
Use cases
- Checking how a Cyrillic domain name appears in DNS records
- Configuring DNS settings for internationalized domain names
- Verifying domain ownership across different encoding formats
Frequently asked questions
