	Are the origin changes for a small set of the prefixes
that tend to repeat (eg: connexion as planes move), or is it a different
set of prefixes day-to-day or week-to-week?

	I suspect there are the obvious prefixes that don't change
(eg: 12/8, 18/8, 35/8, 38/8)  but subparts of that may change, but
for most people with allocations in the range of 12-17 bits, I suspect
they won't change frequently.
