That depends on how you're configuring the IP address.  The prefix
assigned to your network isn't "owned" by you; your upstream provider can
renumber you to a different one if they need to.  The rest of your
address, aside from the prefix, is determined by what method you're using
to configure your hosts.  If you're using stateless autoconfiguration,
which is what radvd is intended to support, then your address is based on
the MAC address of your network card, so when you change your network card
your IP address will change.  This happens fairly infrequently, though, 
and when it does happen you're surely aware of it.  (Because you're the 
one standing there pulling out the bad card and putting in a new one...)

Sure.  You'd have to do it manually rather than using stateless 
autoconfiguration, though.  -Nathan
