Chuck, I don't know if you're keeping any whois lookup statistics, but
it might be worthwhile to do some stress testing of whatever system
you're using to limit whois access, and/or to cross reference some data
and see if your port limiter is working too enthusastically.

I've hit limits on a number of recent occasions, from servers that
I *know* were not doing anything untoward.  In one case, the blocked
host was my database server, from which I had done a total of about
five lookups in half an hour.  Meanwhile, my mail server does lookups
at five-to-thirty second intervals whenever someone sends email to
[EMAIL PROTECTED], and to my knowledge it has never yet been blocked.

Does the limiter block whole networks, or just individual hosts?
