IP addressing

The 10.X.X.X IP range as well as 192.168.1.X are both classified as private IP ranges. Routers will not route them as they are there for use on internal networks only. Because of the shortage of IP addresses out there, this was one way of freeing uppublic addresses. This allows virtually any company to use the same internal address without IP conflicts out on the net.

When standards were developed for IP, it was determined that certain address ranges would be designated for private use, and would be "unroutable" (useless) over the Internet. There are three address ranges designated as private:

10.x.x.x (ClassA networks that start with 10.)

172.16.x.x (Class B networks that start with 172.16.)

192.168.1.x (Class C networks that start with 192.168.1.)

With few exceptions, everything else falls into the "public" (routable) domain.
