IDN

From DreamHost

DreamHost definitely does offer Internationalized Domain Name (IDN) hosting, but it may not be immediately obvious.

Converting your IDN

In order to host an IDN, you need to convert the original URL (containing non-ASCII characters) into Punycode (ACE). This can be done at a site such as idnconvert.com.

Hosting your IDN

To host your IDN, you just have to set it up like you would any other domain, after you've converted it as mentioned above. To set up hosting for it, please click the 'Add New Domain/Sub Domain' button found in your control panel here: Manage Domains. Enter in the converted IDN (Punycode value) as the hosted domain and configure per your liking. Click the button to confirm the setup and you should be directed to a page with a green success message saying the domain has properly been set up for hosting.

IDN TLDs

Dreamhost does not currently support the registration of Chinese IDN TLDs such as .xn--55qx5d (.网络) and .xn--io0a7i (.公司), as they are not currently a component of the ICANN DNS root and thus are not available to all Internet users.

IDN domains under standard TLDs are available for registration, subject to any restrictions which the registry may have enforced.
