Hello Dónal, Here's the situation in our set up.
The Airport Express has two IP addresses, 192.168.01.80 and 169.254.02.110 both of which are local to our own network. Our base station also has the address 192.168.01.05 in addition, to the address on the subnet of 169.254.76.236. The Mybook World backup NAS has the address 192.168.1.129 We've allocated fixed IP addresses to most of the devices that connect regularly to our network to avoid that irritating message that some other device is using your IP address. I don't know if this is of any use to you but at least it shows that our Airport Express and one of our Airport Extremes both have two IP addresses. We can't find the other Airport Extreme which probably means it's offline at the moment. We need all these devices as we live in a very old house with extremely thick stone walls!
