ACK. I meant "force" as in "force as fast as possible" - which may take
days.
Since we want to/must handle partitioned networks, there is IMHO no
concept as "immediately" or "at once" or similar (similar to the clock
synchronization world where no "at the same time" exists).
Which is leads to my conviction that any scheme/system/network that does
not rely on organisational static IP address configuration must handle
IP address duplication graceful - plain simply because every change
takes measurable time.
If DHCP/AHCP/.. is enough for it is another question. Let alone
applications that must deal with changing IP addresses.
