If you wish to register a place name as a domain eg. mytown.ie you will need written permission from the local authority:
"3.6: The proposed domain name must not contravene the geographical name regulation. This regulation requires that no domain name may consist of geographical name(s), word(s) or description(s), or a combination of such, followed by .ie, which in the view of the Registry would be likely to be misleading if registered in the name of the applicant, or if registered would be likely to infer or to imply that the applicant had exclusive or certain rights emanating from such a domain name.
These names, which can most often be defined as names that appear on official maps, are only registered to relevant local authorities. The Registry will not be involved in arrangements between local authorities and third parties regarding the use of the domain name. Quasi-geographical names that do not appear on official maps, such as Leeside, Bayside, Liffey Valley etc. are usually acceptable domain name applications from non-local authority applicants. Applications comprising corporate names, Trade Marks etc. and which include a (real) geographical name are usually compelled to include the "product" name in the domain name. For example, Westmeath Mountaineering Products would be obliged to include "mountaineering", or a derivation, at a minimum, in their domain name."
