Acceptance of an automatically selected IP
address makes management of the AP difficult,
as its IP address will be unknown, but doesn't
directly affect its operation. The AP will accept
such offers regardless. Administrators are
advised to allocate IP addresses manually for
APs if this is an issue.

A dynamic address which expires (i.e. if lease

In this case, the log records the reboot and the
reason as DHCP lease expiry.
