Hello, Ted, Thanks a lot for your comments (past and present ;-) )! In-line....

Just me double-checking: Do you mean it would be to short for them? Please note that the default router lifetime is 1800 seconds. So a host that sleeps for longer than that will presumably not have a default router when it wakes up, and would need to do a "refresh" procedure (RS/RA exchange) before it would be able to send a packet, anyway. > At the same time such a device likely is not relying on RA, since it > would not be awake for periodic refreshes.

Please clarify the above, and based on that, we could craft some text if necessary. Thanks!
