I guess what you want is a "hidden slave", just like an ordinary slave nameserver except not listed as one of the NS hosts. > How to configure this backup NS In the master's zone statement, you need an "also-notify" to send notifies to this slave.

A "type forward" or "type stub" or even "type slave" (where the local DNS server slaves from the hidden slave as its master) are among them. The BIND 9 ARM is a very good resource. Chapter 6 is the main reference part, but you might find useful examples in Chapter 4. https://kb.isc.org/article/AA-00845/ -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject: _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
