All computers connected to the Internet have unique numerical addresses to make sure that information gets to the right place. The domain name system (DNS) changes these numerical addresses into text based domain names to make it easier to find the information you are looking for. The Internet address .ie lets people know that your website is in, from, or related to Ireland. Domain names identify particular web pages. For example, in the web site address http://www.why.ie the domain name is why.ie. Domain names are also used in e-mail addresses, firstname.lastname@why.ie
