Determines how bbtest-net finds the IP adresses of the hosts to test.
By default (the "standard"), bbtest-net does a DNS lookup of the hostname
to determine the IP address, unless the host has the "testip"
tag, or the DNS lookup fails.
<br>
With "--dns=only" bbtest-net will ONLY do the DNS lookup;
it it fails, then all services on that host will be
reported as being down.
<br>
With "--dns=ip" bbtest-net will never do a DNS lookup;
it will use the IP adresse specified in bb-hosts for
the tests. Thus, this setting is equivalent to having
the "testip" tag on all hosts. Note that http tests
will ignore this setting and still perform a DNS
lookup for the hostname given in the URL; see the
"bbtest-net tags for HTTP tests" section in
<i><a href="http://www.hswn.dk/hobbit/help/manpages/man5/bb-hosts.5.html">bb-hosts</a>(5)</i></dd></dl><br><br>T.J.

I have many items monitored by hobbit which are not registered in DNS (I live
with a bunch of windows centric team mates and they rely on WINS not
DNS. None of these items end up with conn=red, but they are ID'd in
the output from bbtest on the hobbit server. Here is that output:</span></font></p>

<br>
The hobbit server when doing fping conn test, it will try using FQDN and if<br>
not resolvable,<br>
it will use the ip address(from bb-hosts) file.<br>
<br>
Is this a correct statement ?<br>
<br>
I will summarize the answer here<br>
