There are a few Private ip ranges that are reserved for Home/Internal corporate networks. Here is what google lists
IPv4 Private Ranges:
The Internet Assigned Numbers Authority (IANA) reserves three IPv4 address ranges for private networks:
- 10.0.0.0 - 10.255.255.255 (10/8 prefix)
- 172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
- 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)
They are just reserved for private use and should not be put on the internet. That doesn't mean they can't be routed internally. Most common we see 192.168.x.x used at home with home routers, I have seen a few use 172.16.x.x. My office has used 10.x.x.x allot over the years though, and i would expect many others do as well.
