Hi.
I read your link about publishing real FQDNs an IPs, however I'm very
reluctant to this ... I explain ... I'm not the super pro (as you noticed
already) in this subject and I don't really know about the full range of
potential consequences. I see already now some AXFR attempts from IPs from
parts of the world, where I know that none of my users is or was at this
place. I also do fully understand that you are willing to help (thank you!)
but you need data to feed the machine (clear!). I take this more or less as
a challenge to figure out by myself what goes wrong and why. I just would
need some kicks in the right direction.
This type of traffic is really common. You'll see all sorts of things
trying to do AXFRs from you, DDNS updates, etc. You're probably only
noticing it now because you've been looking into this issue/paying
attention to it.
As far as I understood, the master server checks the MNAME field of the SOA
and doesn't send a NOTIFY to this NS server (id est it takes it out from the
list of NS records found in the master server's database), since this would
result in a self notification. So ... PowerDNS shouldn't notify itself even
without the "prevent-self-notification=yes" option, right?
Thanks,
