What is Punycode
DNS only handles ASCII, so domains with non-Latin scripts (like Cyrillic .рф) are encoded into an ASCII form such as xn--... via Punycode (RFC 3492). The browser shows the pretty name while talking to the encoded one under the hood.
Why it's useful
The converter reveals a domain's real ASCII form — handy for DNS and certificate setup and for spotting phishing (look-alike letters from different alphabets). Conversion runs right in your browser. To hide your traffic, use GANVAS VPN.
