Mobile IP (Overview)

Mobile Internet Protocol (IP) enables the transfer of information between mobile computers. Mobile computers include lap tops and wireless communications. The mobile computer can change its location to a foreign network. At the foreign network, the mobile computer can still communicate through the home network of the mobile computer. The Solaris implementation of Mobile IP supports only IPv4.
