An IP address is considered private if the IP number falls
within one of the IP address ranges reserved for private
uses by Internet standards groups. These private IP address
ranges exist:

      10.0.0.0 through 10.255.255.255
      169.254.0.0 through 169.254.255.255 (APIPA only)
      172.16.0.0 through 172.31.255.255
      192.168.0.0 through 192.168.255.255 

Private IP addresses are typically used on local networks
including home, school and business LANs including airports
and hotels. 
Rest of the IP's are known as Public IP and those IP's are
routable on Internet.
