There are 2 types of IP addresses: public and private. Public IP addresses are accessible from the Internet, while Private IP addresses are not. You would use private addresses in a LAN for more security, and have one computer that acts as the gateway and runs a NAT (network address translater,) which would translate the private address into a public one for Internet access.

There are reserved blocks of the IP address space for private internets:

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255

"invalid ip" mean an ip address listed in the reserved block. Those address are reserved for local network and are non-routable.
