       gdnsd-plugin-reflect is a resolution plugin that acts as a live
       debugging tool.  It reflects a view of the client's network address
       back in the response in the form of "A" or "AAAA" RRs.  It can be used
       with both "DYNA" and "DYNC" RRs, and will return address data in both

       The plugin can operate in one of four modes named "dns", "edns",
       "both", and "best", which can be selected by using the mode name as a
       resource name in the zonefile, as shown in the example above.  The
       default mode is "best".  The modes operate as follows:

       dns In the "dns" mode, the address in the response is always the source
           IP address of the request as seen by gdnsd.  Note that this is
           generally the public address of a central cache/resolver server
           rather than the end-user client itself.

           In the "edns" mode, the address in the response is the address sent
           by the client in the "edns-client-subnet" option.  If the client
           did not send such an option, the IPv4 address is returned.

           In the "both" mode, both of the above results are returned in the
           same response, but there is no artificial added if no
           "edns-client-subnet" option was available.

           In the "best" (default) mode, if the "edns-client-subnet" option
           was specified its data is returned as in the "edns" case, otherwise
           the source IP address is returned as in the "dns" case.
