Re: Anyone else blacklisted this morning by rbl.iprange.net?

Apparently they're widely used by firewall-based anti spam, as we seem to be getting blocked a lot by Juniper, 
Sonicwall, and Palo Alto firewalls. The outfit is listed in 
https://en.m.wikipedia.org/wiki/Comparison_of_DNS_blacklists, but seem to have very poor communication options (e.g., 
WhoIs is obscured).

Why don't they just quit answering DNS queries at rbl.iprange.net? Sheesh!
