Well, remember the AirPort Express is an access point, it is also a print server and an MP3 streaming client - it is the last two functions (that I assume) would be IP address sensitive. For example, to access an AirPort Express printer from a windows client, you need to set the IP address of the Apple AirPort Express, which could change.

My Linksys cable router is my DHCP server.

I thought DHCP addresses had a lifetime, and when that was up it could be renewed (retained) by a device, but if the device is not powered up when the address "expired", it could not request an extension, hence losing the address...
