Private IP Address
                       The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets (local networks):

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255


These IP's should not be used on the Internet.
                 I usually use 192.168.0.1, 192.168.0.2, etc. and a subnet mask of 255.255.255.0 when assigning static IP addresses to computers on a small Local Area Networks (LANs).  If a DHCP server is also on the LAN it's scope (range of IP addresses that it can assign to computers on the LAN set to obtain their IP addresses automatically) should be adjusted so it does not interfere with locally assigned static IP addresses.
