About the relation of IP and AS

You can go to Arin's web page, click on the whois Link.  Whois the Ip, and
then whois the Owner.

Example
Whois for my dns server 216.142.210.x = Broadslate Networks
Whois for Broadslate Networks = as 16770

Good Luck, 
Ejay

Hi,
Is there some relations between IP address and AS numbers? I want to kn
ow an IP belong to which AS and the IPs an AS have. Where can I find it?
Thanks a lot.
