global whois servers ??

[Ken Hardy <ken @ bridge . com>]

I'm trying to determine who's up to some mischief as indicated by my
firewall logs.  They're coming from a .com.au domain.  I'm aware of
rs.internic.net for US domains and whois.ripe.net for European, but
what about .au, etc.

Does anyone know of a comprehensive list of whois server (or other
means) for learning information about various domains around the world,
such as contacts?  Thanks.
