How it works ?

Mobile IPv6 identifies each node by its unchanging global home address, regardless of its current point of attachment to the Internet

While a mobile node is away from home it sends information about its current location (I.e. primary care-of address) to a home agent on its home link

The home agent intercepts packets addressed to the mobile node’s home address and tunnels them to the mobile node’s current location (I.e. primary care-of address)
