I will explain what I do with my small network.

I was given 3 /24 class C style network numbers to start with.

I subnetted the first one up using a netmask of .224 (8 segments), 
the second one I did not subnet (for web access), and the third I used as 
another .224 subnet for routing multiple IP segments.

I think a lot of the ISP's out there use multiple /24 class C networks by 
using routers between them.  Or, in many cases having multiple networks 
on one router.

I use mine for web hosting, and I have multiple downstream hosts via 
frame relay, ISDN, and modem dialup.

Hope that helps, any other questions please feel free to email.
