I have no idea where you got this idea from, but it is totally false. For
starters, the NIC has nothing to do with IP addresses or subnets. All it
deals with is a mac address. It is linux that does the mapping from IP to
MAC and back. Secondly, while it may not be the cleanest thing to do, it
is certainly allowed to have a NIC handle IP addresses in multiple
subnets. Routers do this all the time. Ex: 192.168.10.0 and 10.0.1.0 on
the same enet port. If a 192.168.10.0 host tries to (for example) ping a
10.0.1.0 host, the packet will go into the router and back out the same
enet port (this is called one-armed routing).
