About this tool
Convert between Unicode domain names and Punycode encoding. Internationalized Domain Names (IDN) use non-ASCII characters (e.g., münchen.de, 日本語.jp) but DNS only supports ASCII. Punycode encodes Unicode characters into ASCII-compatible strings prefixed with xn-- (e.g., xn--mnchen-3ya.de). Use it for debugging DNS issues with international domains, verifying IDN registrations, and understanding how non-ASCII domains are resolved.
