to different Autonomous systems.

Is there a central/distributed database somewhere that can tell me
that this particular IP prefix (say x.y.z.w) has been given to foo AS

I tried searching through all the WHOIS records for a domain name. I
get the IP address but i dont get the AS number.

Any clues on how i can get the AS number?
