Use Cases & Examples
Registering International Domains
Convert your desired local-language domain name to Punycode to check availability or register it with providers that require ASCII input.
Debugging DNS Issues
Troubleshoot DNS records by converting between the display name (Unicode) and the actual DNS entry (Punycode).
Email Configuration
Ensure email servers correctly handle IDN addresses by verifying their Punycode representation.
What is Punycode?
Punycode is a special encoding used to convert Unicode characters into the limited ASCII character set supported by the Domain Name System (DNS).
It allows domains like 'café.com' to be represented as 'xn--caf-dma.com'.
The 'xn--' prefix indicates that the domain is an IDN encoded in Punycode.
Frequently Asked Questions
Q.What is an IDN?
A. IDN stands for Internationalized Domain Name. It refers to domain names that contain characters beyond the standard ASCII set, such as letters with diacritics, Chinese characters, or emojis.
Q.Why do I need Punycode?
A. The core infrastructure of the Internet (DNS) was originally designed to support only ASCII characters. Punycode bridges this gap by representing Unicode characters using only ASCII, ensuring compatibility.
Q.Is my data sent to a server?
A. No. This tool runs entirely in your browser using JavaScript. Your domain names are processed locally and are never uploaded to any server.
