What you want for this is random or sequentional reordering of the
recordset on consecutive queries so that resolvers use the different
IP-numbers to spread the load. Most (almost all end-user) resolvers
do not do the recursing themselves, but use caching-forwarders.
Stub-resolvers, which use caching-forwarders, will thus never query
an NSD nameserver, as NSD is authoritative-only.
Caching-forwarders may or may not be setup to reorder.
Now, to answer you question more directly:
NSD does not re-order the recordset, but for load balancing
this is of little importance, as it is the behaviour of the
caching-forwarders which does the trick.
