A standard PolyMix-4 workload uses a single DNS server.

The Resolver PGL type supports multiple servers. Polygraph has code
to support multiple servers as well, but I do not recall whether that
feature was ever tested/used. A robot is supposed to query DNS servers
in the order they are specified and stop with the first response to a
query. That is, server N will be queried only if all N-1 servers
before it did not respond (the queries to them timed out). If you
think there is a bug, please send details to bugs at
web-polygraph.org.

Please note that you need to use single quotes for address constants:

        Resolver.servers = [ '172.16.100.191-194:53' ];

HTH,
