It was nice to see the RFC being published. Good work.
Then I came across this:
http://blog.vamsoft.com/2012/01/24/ub-black-uribl-com-url-blacklist-started-to-block-everything/
(Vamsoft ORF is a spam-filter.) Basically uribl.com was returning 127.0.0.1 to
_all_ queries from nameservers that are sending high volumes (presumably
without paying for it) as some kind of punishment. http://uribl.com/ confirms
that.
Now, as Vamsoft mentions, it is not a good idea to use third-party nameservers
on a server you're making DNS requests from. (Although, unlike openDNS,
Google's nameservers do return NXDOMAIN when they can't resolve a domain.)
Moreover, it does seem Google's nameservers are now getting REFUSED as a
response to any uribl.com request. I was just wondering whether the RFC says
anything about this kind of behaviour ('listing' everything as a punishment).
To my reading it doesn't.
