    I have a multi server setup of ispconfig. Do I need to enter ip in the zone setting of the following fields
    - Allow zone transfers to these IPs (comma separated list)
    - Also Notify
    I am guessing no need because the multi server setup will do the dns syncing. Correct?
    And when do I use "Secondary DNS Zones" ? Do I need it when using multi server setup?

    You DON'T want to use a multi server setup for DNS services!
    At least not when DNSSEC is active in DNS zones.

    For DNS use a master-secondary setup.
    Then you have to setup zone transfer and notify fields in order for the secondary zone to propagate the records in the master zone.

    It depends on how you set it up. ISPConfig supports several ways to set up a multiserver setup, and the standard way we use today, which is described in the most recent multiserver guides, supports DNNSEC. @remkoh is right, though, that older setups that used mirroring in a multiserver setup did not support DNSSEC.

    So, back to the first post, it depends on how you installed your system. is the secondary DNS just a slave node (then it supports DNSSEC and you must create a secondary zone in ISPConfig), or is it a mirror node, then it does not support DNSSEC, but you don't have to create a slave zone.

    I assumed he ment mirrored servers, as most do when mentioning multi server setup.
