To register a .ie domain name
truly is a pain in the ass in comparison to registering a .com
To even apply to reserve a domain one has to fall under one of the following categories:
Limited Company registering its own name
Limited Company registering a trading name
Limited Company registered outside Ireland
Which basically means that your average Joe Lunchbox can't just go ahead and and register www.hardcoreleprechauns.ie, he would actually have to set up a limited company in that name, which involves solicitors, accountants and a lot of hassle that you could do without. The application process is long and slow. On top of this, .ie domains cost €126.97 to set up and the same amount for the annual "maintainence fee".
The Irish domain registry was originally housed in University College Dublin but it seems they have scuttled off to a new lair nearby in Sandycove, Co. Dublin. Their offices are "closed to the public" so don't bother popping around for a cup of tea and a chinwag.
You will probably be given a polite "Feck off".
