Difference between permanent address and care-of address:
|Permanent address||Care-of address|
|An IP address given to a mobile node in its home network is called the permanent address.||An IP address given to a mobile node in a foreign network is called the care-of address.|
|It is a permanent address given to a mobile node.||It is a temporary address given to a mobile node.|
The foreign agent assigns care-of address for mobile nodes in a foreign network. The care-of addresses are automatically de-registered when the mobile nodes moves to a new network.
