	You seem to be noticing 3 kinds of error.

	"Network unreachable" messages refer only to IPv6 destinations.
	Perhaps you have IPv6 enabled on the system where you're running
	named, but don't have any external IPv6 connectivity?

	"Connection refused" or "format error" (duplicated confusingly as
	"FORMERR") indicate that a remote name server has refused to handle
	your request or has sent a badly-formed response.  You can expect
	to see these all the time when you run a resolver.  There are
	broken and misconfigured servers out there!

	I hope this helps.
