Yes.
the moudle name suffix "4", "6", or "" specifies the family of the addresses
that
are resolved. i.e. specifies whether A, AAAA or both RRs should be
looked for.
If --enable-legacy is passed, than only IPv4 UDP packets will be used
for resolving - unless avahi-daemon is found in which case also IPv6
UDP packets are used.
If --disable-legacy is passed nss-mdns relies exclusively on
avahi-daemon and thus both IPv4 UDP and IPv6 UDP is used (depending on
the daemon config).
The "_minimal" just modifies the behaviour for host names not ending
in .local and addresses not starting with 169.254/fe80::.
Yeah, I know, it's confusing. ;-)
The major issue is to understand that you can resolve A records via
both IPv4 and IPv6 and the same is true for AAAA records. A records
are address records for IPv4, and AAAA are records for IPv6 addresses.
Is that cleared up now?
