ABSTRACT:
Propagation of a mobile platform's public IP address though Internet service providers is monitored as the mobile platform is handed-off from a first ground station to a second ground station. The mobile platform's public IP address is removed from the first ground station. The first ground station is checked to determine whether the mobile platform's public IP address is no longer present there. After a predetermined period, the second ground station is checked to determine whether the mobile platform's public IP address is no longer present at the first ground station. The mobile platform's public IP address is added to the second ground station. The second ground station is checked to determine whether the mobile platform's public IP address is now present there. After a predetermined period, the first ground station is checked to determine whether the mobile platform's public IP address is now present at the second ground station.
