The list of nameservers is a prioritized lists, so by trying a random
nameserver you may get different DNS results returned, compared to using
them in sorted orders. Nameservers may also be ordered by locality, for
example the first 2 nameservers are on my local LAN, but the 3rd nameserver
is a 'failsafe' on the WAN. The first will give much faster loookup result
that the last.
