Mobility

[Francis Dupont]

 In your previous mail you wrote:

   When PC boots in home link it gets its "home" IP address. Then it shuts down
   and moves to foreign link. On foreign link boots up and get "care-of"
   address via autoconfiguration. How does that "mobile" node know that this is
   a care-of address and not his home address.
   
=> we discussed about this problem at the last IETF meeting
in the zero-conf session. I believe there is no good way for the
software to know if the node is at home or in visit (same question
at a more abstrat level) without some config (for instance the home
address or prefix: a simple match will be enough) or a human interaction.
Then the answer is the mobile node knows because someone gives this info
to it, it cannot know by itself.

PS: in order to find a home agent the mobile node needs something like
the home prefix then I believe the common solution is to put the home
prefix in a config file or to give it as a parameter to a management tool.
