0 and 255 are network/broadcast addresses.  Most BB routers have address
1 or 254.

You can do "netstat -rn" and look up the gateway for destination "0.0.0.0"
while the machine is under DHCP.

Most BB routers can proxy DNS also, and this will usually yield the IP
of the BB router.

Another way to do it is let clients use DHCP and assigning IPs
statically by ethernet MAC at the BB router, if the router supports it. 
I like to do it this way because it keeps the clients simple, keeps the
information at one place and you don't need to worry about IP address
clashes.
