The top level naming system of the internet is expanding to include non-roman characters and a multitude of new suffixes. The familiar .edu, .net, .com, .countrycodes will be joined by
as well as
and lots and lots of others.

IT departments and software companies are scrabbling to ensure compatibility and reliability of internet services.

Lets hope the preparation work gets done and the new gTLDs have the same minimal impact as Y2K. Somehow I doubt it.
