DNS failures mean just that - the DNS lookup for "host.domain.local"
failed. 

Note that Hobbit will perform a DNS lookup of the hostname in the URL, 
regardless of what host this status is reported for. E.g. 

   10.0.0.1   myserver.foo.com  # http://www.foo.com/

will do a DNS lookup of "www.foo.com" to get the IP-address for the 
http tests. The "testip" flag has no effect on http tests; if you
want to force an http test to use a specific IP-address (and hence
avoid the DNS lookup), you can do it like this:

   10.0.0.1   myserver.foo.com  # http://www.foo.com=192.168.1.7/

This will make the http tests use the 192.168.1.7 address.
