[AusNOG] Hands up who has AS112 Like reverse DNS infrastructure

[Matt Perkins]

Hi All,
  I was wondering what all your thoughts would be about AS112 Like 
Black-hole reverse lookup infrastructure might be across the CSP space. 
Seems that people do things as little as simply adding blackhole'd zones 
for the RFC1918 ranges right up to dedicated infrastructure and even 
their own instance  AS112.

I have been doing simple blackhole'ed zones on our main caching dns 
infrastructure for now but I dont really have a good handle on how much 
resources this is actually using. I know a fair few ISP's are sending 
this through to the keeper. Which is not ideal if it goes away for any 
reason.

Anybody care to share their insights .

Matt.
