The IrishWAN uses the 10.x.x.x address space. Each WAN region (which is often, but not always, a county) has a class B address space (10.n.x.x) allocated by the IrishWAN. The top-level ip ranges are currently managed by bkehoe@irishwan.net. Mail him if you require a new regional ip range.
There is a GalwayWAN website but the content isn't currently being updated so this list is definitive until further notice. If you are in the Galway region and interested in connecting into the GalwayWAN, please contact stephen@skynet.ie for an address or set of addresses (please provide some details of your setup including how many nodes you expect to be connected to the WAN via you).
