Use this if you want to specify a list of DNS name servers
	(IP addresses) to use instead of those given in your
	/etc/resolv.conf file.
	On Windows platforms, if no value is specified here or in
	the /etc/resolv.conf file, the list of DNS name servers are
	taken from the Windows registry, both static and dynamic DHCP
	configurations are supported.

	Example: dns_nameservers 10.0.0.1 192.172.0.4
