Is there a way to get the past owners on IP blocks and AS numbers?
for the routing history: https://stat.ripe.net/m/widget/routing-history#w.resource=193.0.21.44 (link to mobile version -> "/m") for the allocation history: https://stat.ripe.net/m/widget/allocation-history#w.resource=192.0.21.44 (without "/m") And, today released BGPlay2 can be useful too: https://labs.ripe.net/Members/vastur/bgplay-v2-integrated-in-ripestat For RIPE NCC members, it is possible see the history of _registration in whois_, of IP ranges and AS numbers, and related objects: https://labs.ripe.net/Members/dfk/registration-history-for-members-a-demo I hope this helps.
