That's true and false.

First, bridges don't need any IP address, as they are working on level
below.
Thus both networks eth0 and eth1 should be the same network and subnet.

The IP configuration for the bridge itself is used as the ip and subnet of
the local system.
If you want to send from the local system, it needs to know the routes and
therefor you need a proper netmask.
(255.255.255.255 is special for PPP but unusable for LANs.)
