Reindl,

Please do not top post.

255.255.255.248 gives you a total of 8 IPs, not 10, of which usually you 
loose 3 for the network, broadcast and gw addresses.
You can assign those 5 in a range file without problems, you can also 
specify the netmask like in a "normal" cfg file. It shouldn't be needed to 
specify other settings.

Where I work we'd route the additional subnet through the IP you already 
have on the server, thus allowing you to allocate _all_ 8 IPs as a range 
on the loopback interface with a /32 netmask. See if your ISP can do this 
for you.
