Subject: [as112-ops] Anycast DNS servers don't respond anymore from Roamania
Message-ID: <AANLkTinohNTWXSoux-z2XXs_1LzsECz3feZ-Zfs-rz22@mail.gmail.com>

192.175.48.6
192.175.48.42

These servers don't respond anymore to bogus rfc1918 PTR queries from
Romania. This slows everything down in LAN's from mail delivery to samba
shares. Please take a look, maybe you can fix them. I don't know their non
anycast ip addresses but i can provde a mtr for them.

if your network uses AS112 nameservers for your RFC1918 reverse zone you 
should check your resolvers and fix them. Properly configured resolvers 
should not forward requests to AS112 nameservers.

"dig txt hostname.as112.net" should answer those questions.

Hello Emil,

If you're facing these problems on your own network, I recommend that
you don't rely on the AS112 servers for responses. Instead, configure
your caching resolvers with these zones and provide the responses
yourself. Ideally, PTR queries for RFC 1918 address space should never
leave a properly-configured network.
