They've squeezed the subnets down to 255.255.255.254 now? They'd reduced them from .0 to .128 last year, .254 seems almost implausibly small though.
Also, with regards to your actual comment, everyone will have the same subnet "number", usually 255.255.255.
x, but that doesn't make them on the same "physical" subnet. As I say, it's generally split by flats/hall divisions - basically wherever they have a router.
