This breaks much of the nice feature with route optimazation and we are back
to the less nice mobile
ipv4 solution... And I dont see why it is needed?
This would only eat up more of the operators available network bandwidth ...
What is location privacy - I said it on the mobile IP list and I say it
again that I would argue that it is not something we want...
If you are willing to let the packet take a longer route via its home
network what do you achieve...?
This also leads to Itojun question when a CN wanted to know the CoA of the
mobile node... Why do the application (and the BSD API) need to have any
knowledge about this...? And if the API dont have any way to get the CoA
then this would not be a problem and the home address option would work as
its suppose to work (using the HA) - to hide everything to the transport
layers...
In ipv6 you have the address diveded into two parts and it is only of
interest to a "spoofer" what your lower 64 bits are (i.e. your interface id
or EUI-64)..
And there is a draft how you add privacy to the interface part
(http://www.ietf.org/internet-drafts/draft-ietf-ipngwg-addrconf-privacy-01.t
xt*)
That means that you cant be tracked... Eventhough a spoofer sees where the
packets comes from he cant reveil from who it is originated... In other
words there are already a solution to the privacy issue... So the privacy
issue is not an valid for having the BU turned off... this solves the
privacy for the user but do you ever want to have location privacy??
