Hi Evren,

from "man 5 resolver":

     nameserver  Internet address (in dot notation) of a name server that the
		 resolver should query.  Up to MAXNS (currently 3) name
		 servers may be listed, one per keyword.  If there are multi-
		 ple servers, the resolver library queries them in the order
		 listed.  If no nameserver entries are present, the default is
		 to use the name server on the local machine.  (The algorithm
		 used is to try a name server, and if the query times out, try
		 the next, until out of name servers, then repeat trying all
		 the name servers until a maximum number of retries are made).
