What purpose, if any, do non-authoritative DNS zone files serve?

    Hi,

    As per the title: what purpose, if any, do non-authoritative DNS zone files serve? If the answer is "none", then IMHO it should be a standard feature of WHM to identify non-authoritative DNS files and offer them up for deletion.

    Thanks for your feedback on this,

    Ross

    Ironically I was asking the same question way back here in 2006!

    http://forums.cpanel.net/f5/identifying-non-authoritative-dns-zone-files-59813.html

    I just think/observe that non-authoritative DNS zone files have the potential to really mislead humans, and create technical issues.

    * When viewing/editing zone files in WHM, there is nothing to distinguish an authoritative zone file from a non-authoritative one - thereby creating the potential for human confusion.
    * Non-authoritative DNS zone files have the potential to give incorrect instructions to the local web server, e.g. most typically on how to handle mail (i.e. locally or remotely).

    What am I missing here?! What value, if any, do non-authoritative DNS zone files have on a WHM server?

    Thx.

    Hello :)

    There are no native options in cPanel that will prevent the creation or allow for the automatic detection/removal of a DNS Zone when the server is non-authoritative. One reason is so the zone will exist if a customer chooses to use the cPanel server as the authoritative DNS server. The best way to see this type of functionality is to open a feature request:

    Thank you.

    Thanks for that.

    I've opened a feature request here: Login Form | cPanel Feature Requests

    I accept/agree that some sort of auto-deletion policy for non-authoritative DNS zone files is a bit harsh/risky, but at a bare minimum I think a sensible approach is to either

    1. Much more clearly highlight to a WHM admin where a zone files is not authoritative, and/or
    2. Auto suspend/disable such zone files so that they're not permitted to be active and appear as authoritative to the local server (and potentially cause the server to be given incorrect information).
