- by default (but not actually with most operating systems?), the client
   device MAC address gets used as the lower 64bits of auto-configured IP
   addresses, leaking a universally unique identified of the device. 

 - Instead of DHCP, Neighbor Discovery leads to a globaly-routable address very
   quickly. 

 - Secure Neighbor Discovery Protocol (SEND) is patent-encumbered... but
   something like this is necessary to prevent malicious MITM?

 - IP Mobility

Questions:

 - How fast is neighbor discovery?

 - How fast is IP Mobility handover?
