Punycode and IDN

Domains can hold any script, but DNS only carries ASCII, so anything else is packed into an xn-- label. This converts either way and shows you the working.

Domain, address or link

Type or paste it

A bare domain, a full link, or an email address. Each label is converted on its own, which is how DNS does it.

Try one

Both forms

Unicode

ASCII, as DNS sees it

Label by label

Lookalike check

Type a domain to check it.

Mixing scripts inside one label is how a fake address is usually built: Latin a and Cyrillic а look identical but are different characters.
