I've gone through many linux servers on different networks configuring NIC cards, and I've noticed that every IP address on a single interface always has the same Bcast address.
This command:
It lists the "Bcast" address on each of the eth0 interfaces,
eth0
eth0:1
eth0:2
etc etc
Althought the Bcast address may change from server to server, I've never ever seen it different from interface to interface on eth0
Is it possible to ever be different? And if so, in what case?
The reason I ask is because I'm configuring my firewall to drop packets pretending to be from the broadcast address, and wondered if I ever had to worry about there being a different value, then from the one that I always see there, if we were to add another IP address on the box.
