Is there a reason why you would use a 10.x.x.x over a 192.168.x.x network, or vice versa? Even for a small company, is there a reason why you wouldn't just use the 10.x.x.x address space even though it provides way more addresses than you will actually use? Is there a downside to having a lot of unused private addresses in the address space you are using?

Greetings,
In theory, as long as ALL your devices support Classless Routing (if a device is still Classfull then it is EXTREMELY OLD and should be discarded IMHO), then it doesn't matter in the slightest, its the Network MASK that will determine the range of addresses valid for that particular segment. The only down side I can think of to using a Class A mask is that any Malware could blow most device ARP tables, but if you are into that situation you have other problems to resolve first.......;-)

Most home routers use 192.168.x.x addresses for the home LAN, so if you're likely to implement VPNs from homes to the main office, it's a good idea to use a range at the main office that's sure not to overlap. So it's generally safest to use 10.x.x.x or 172.[16-31].x.x addresses for the corporate network.
