Are there? For wifi you could look at the SSID (though even that is no
guarantee - for example enterprise networks commonly use just a few
SSIDs, but have different IP address ranges on a per-controller or
per-radio basis). But what about wired? Remember, the same thing
happens when you unplug your laptop's ethernet port and plug it in to
another network.
