Hello,
I'm sending this message to see if I understood the meaning of " RFC
1918 response from Internet" message logs. I read the FAQ of Bind [1], but
I have to be honest to say that I'm a litlle bit confused, since English is
not my first language.
I'm using Bind 9.7.3 in a Debian server. It has a arquive named
zones.rfc1918 [2] that is enabled. I just took off the line refering to
10.0.0.0 network because I'm using it in my organization. I have the
reverse configured for my network, eg: 1.0.10.in-addr.arpa, but I dont have
the reverse for the rest of this network.
If, by mistake or not, a client asks for a address in the 10.0.2.0
network, my server will querying the Internet's name servers for this
address once I dont have it configured and then I will receive message logs
about it [3]. Is that correct?
