Temporary addresses
Issue: how to clients and servers negotiate assignment of temporary addresses and mark addresses as temporary; can client extend lifetime of temporary address?
Resolution:
- Client indicates desire for regular or temporary addresses in IA
- Server assigns addresses as allowed by admin control
- Client may develop new IA for more temporary addresses
- Temporary addresses SHOULD have preferred lifetime of 1 day, valid lifetime of 1 week; server should generate non-repeating sequence of temporary addresses
- Single option with flag bits, separate options, ???
