In my building for a large company the PCs (on a domain) all have an IP address starting with 10.x.x.x. Now this to me is a class A address and the subnet mask should be 255.0.0.0. however the subnet mask on all the Pcs in the office is
255.255.255.0 suggesting a class C address. It has always been this way and I wondered if anyone knew why this is so?
