Hello,

I looked at the slides.  I think I understand the concept of type of IP 
address from a mobility perspective: fixed, sustained, nomadic.

I have remarks:
- could an aquired prefix (DHCPv6 PD) also be qualified as fixed,
   sustained, nomadic?
- how would a mobility address type relate to other address 'types'?
   - link-local, ULA, global.
   - unicast, anycast, multicast.
   - MAC-based, random-based (RFC7217).
   - configured by SLAAC, by DHCPv6, by PPP, or registered (RFC 6775).

E.g. a nomadic address could never be a link-local address.

> #2. Describe how IP address type information is conveyed from network to MN.

If one designs a protocol to convey address type information from the 
network to the end node, then one could also add the other types 
mentioned above.

SLAAC could never 'convey' the address type to the end-node, because 
SLAAC is an operation happening with as heavy weight from the Server 
(router) as from the Client (Host): the Router decides the prefix but 
the Client decides the Interface ID.

Address Registration Option of 6lo and BTLE would have the Host 
conveying this information to the Router (and not vice-versa).

Yours,

Alex
