DNS Right But User Agent Wrong

Ran into a user agent from DNSRight today that claimed to be some link check tool that doesn't appear on their site.

66.240.236.220 "GET / "
"http://www.dnsright.com/" "DNSRight.com WebBot Link Ckeck Tool. Report abuse to: dnsr@dnsright.com"

So I ran some of their other tools that don't identify themselves at all.

66.240.236.220 "GET / HTTP/1.1" "-" "-"

They host this mess at cari.net so just block 'em.

OrgName: California Regional Intranet, Inc.
NetRange: 66.240.192.0 - 66.240.255.255
CIDR: 66.240.192.0/18

No more DNS Right or Left, it's now DNS Gone.
