DESCRIPTIONgdnsd-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
cases.
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.
edns
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 0.0.0.0 is returned.
both
In the "both" mode, both of the above results are returned in the
same response, but there is no artificial 0.0.0.0 added if no
"edns-client-subnet" option was available.
best
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.
