While the number of WIPO UDRP cases involving IE domains is not that big, there are still more than enough to show that trademark holders should pay attention to the IE namespace.
The most recent decision involved the domain “fatboy.ie”.
If you are familiar with them Fatboys are a sort of beanbag. (You can find out more about them here)
In this case the domain fatboy.ie was being used to push traffic towards a competing brand selling a very similar set of products.
You can read the full decision here, but the outcome was pretty predictable and the current holder of fatboy.ie did not respond at any time
