not work on a host with an IP address of a private network or an intranet IP address assigned by
ISPs that start with 100. Common IPv4 addresses are classified into class A, class B and class C.
Private IP addresses of class A range from 10.0.0.0 to 10.255.255.255. Private IP addresses of class
B range from 172.16.0.0 to 172.31.255.255. Private IP addresses of class C range from 192.168.0.0
to 192.168.255.255.
