From MoodleDocs
Private IP addresses cannot be looked up. Private IP addresses are all addresses beginning with:
- 127.
- 10.
- 172.16. to 172.31.
- 192.168.
They are supposed to be used inside private networks, but not within the internet. So they can be used many times all over the world. For more information see wikipeedia
