Hello David,
I am using PHPWhois for a project at work, where I have to do ASN, domain
and NIC-handle lookups.
Studying the code I found out that all IP and ASN searches are done with
ARIN whois server as a first try. Then depending on the response from ARIN,
you decide which Registrar to query later. That is ok for IPs, since ARIN is
able to give you the right registrar for any IP, but it doesn't work with
ASNs. The ARIN server only knows its own ASNs.
I have decided to make a dedicated ASN handler, using another primary
server, like RIPE, who actually can give you the registrar assignated to any
ASN.
When I have it working, I can send you the patch or upload it to
sourceforge.
Thank you for your work in the project.
Best regards,
Marcos.
