Mobile IP is a protocol that allows mobile devices to change location while maintaining the same IP address. It works by assigning mobile devices a permanent home address and registering a care-of address with their home agent when visiting foreign networks. The home agent intercepts packets destined for the mobile device's home address and tunnels them to its current care-of address. This allows the mobile device to stay connected to the internet as it moves between networks while keeping the same home address.
