Checking section 220.127.116.11 of the BIND 9.10 Administrators Reference
In this release of BIND 9, the rrset-order statement does not support
”fixed” ordering by default. Fixed ordering can be enabled at compile
time by specifying ”–enable-fixed-rrset” on the ”configure” command line.
However, my reading of fixed ordering ('the order they are defined in
the zone file') implies it can only work on an authoritative server that
has a full copy of the zone. A server that is iterating will receive
records in the order that the authoritative sorts them, and I don't see
how the iterating server can reorder them against the zone file.
sortlist (section 18.104.22.168 of 9.10) might be more appropriate, but it's
scaled more towards continent-sized address blocks rather than
reordering all answers lexicographically.
