How hobbit server deal with DNS server failure when doing conn test ?

I remember somewhere in the manpages,

The hobbit server when doing fping conn test, it will try using FQDN and if not resolvable, it will use the ip address(from bb-hosts) file.

Is this a correct statement ?

I will summarize the answer here
