Is there a way to get the past owners on IP blocks and AS numbers?
ARIN has a WHOWAS service which requires access permission. For other RIRs, you need to get historical Whois dumps.

For RIPE there is a new beta service to display history of objects in
the RIPE DB

Hi Mike,
you can use RIPEstat: http://stat.ripe.net
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:
For RIPE NCC members, it is possible see the history of
_registration in whois_, of IP ranges and AS numbers, and related objects:
I hope this helps.
Regards,
Vesna
