Wait a second here. Why are you guys even talking about runtime DHCP IP
reconfiguration of a client? That's a giant can of worms for anything but
really dumb clients.
RFC 1531 Dynamic Host Configuration Protocol October 1993
3.6 When clients should use DHCP
A host should use DHCP to reacquire or verify its IP address and
network parameters whenever the local network parameters may have
changed; e.g., at system boot time or after a disconnection from the
local network, as the local network configuration may change without
the host's or user's knowledge.
If a host has knowledge of a previous network address and is unable
to contact a local DHCP server, the host may continue to use the
previous network address until the lease for that address expires.
If the lease expires before the host can contact a DHCP server, the
host must immediately discontinue use of the previous network address
and may inform local users of the problem.
