	For example for any given prefix to get which ASNs have =
originated that prefix over time and when.

	I think that could be interesting for discovering if a prefix =
has been hijacked in the past.

	RIS from RIPE NCC provides something like this:

http://www.ripe.net/data-tools/stats/ris/routing-information-service

	We have used it to verify some "suspicious" announcements of =
prefixes.=20
