DNS Setup of an IDN domain

IDN domains allow non-latin letters to be present in domain names. For example the hungarian word "Cheap" should be spelt as "olcsó" which cannot be resolved with standard DNS due to the accented "ó".

For this purpose, the encoding "punycode" was developed, a punycode converter can be found at http://mct.verisign-grs.com/index.shtml

A sample conversion would be xn--olcs-tqa.hu for olcsó.hu

On a seperate note, Hungarian domains have a unusual requirement, postmaster@.hu must exist. The DNS check at the Hungary NIC has a good check which shows this:

Technical check



Results of the domain check

Congratulations!, the domain xn--xxx-3hb3k88c.hu is configured correctly.

Should you have any questions, do not hesitate to contact hostmaster@ns.nic.hu.

An SEO point to note here, is that although IE6 does not handle IDN domains by default, you do not automatically loose 25% of your audience.

Google and Yahoo both handle IDN domains for IE6 users by redirecting them to the punycode version of the domain.

However, this won't help you with offline advertising.
