Ronan,
Thanks for the reply. blackhole {} looks like a useful option. It
looks like something that I'd also want to use if I wanted a NS that
accepted queries from our customer subnets (via "allow-query" and
"allow-recursion" but blocked everything else "blackhole {any;}.
While I was waiting for a reply I also continued my research and I
believe I found the config option I used to use. "bogus" I'm now
using the sample below:
// ### BOGUS Servers ###
// NS1.ZT-444.COM
server 64.20.39.26 { bogus yes ; };
// NS2.ZT-444.COM
server 64.20.33.130 { bogus yes ; };
// NS3.ZT-444.COM
server 64.20.33.3 { bogus yes ; };
As time permits I'll continue adding NSs that from DNS for Phishing
sites. Thanks for the info.
