DNS config

[sunebeermann]

Hi

When setting up the ispCP i notist that there is an option for providin a secondary DNS ip address. This is greate, my question is now can i provide a network of DNS servers instead of just one IP.
like so 80.80.80.80/16 ?

And how does ispCP provide the DNS settings to the secondary DNS server? is it AFXR or what is it?

Best regards

Sune

AFAIK the secondary DNS setting is only used to generate bind's zone files. This is, for each client domain "domain.tld", the panel adds an NS record "ns2.domain.tld" pointing to this IP, and nothing else.

Therefore, AXFR-enabled clients must be manually configured in /etc/bind/named.conf.options, with an "allow-transfer" directive (where you can put a whole subnet, just check the syntax in bind's docs).
