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