Description knezour 2022-08-04 13:21:21 UTC 
Handbook section 29.5.1. Why do I have to use the FQDN for hosts on my site? mentions BIND shipped with FreeBSD which is no longer actual. Following two paragraphs are misleading regarding current default OS installation.

This is because the version of BIND which ships with FreeBSD no longer provides default abbreviations for non-FQDNs other than the local domain. An unqualified host such as mumble must either be found as mumble.foo.bar.edu, or it will be searched for in the root domain.

In older versions of BIND, the search continued across mumble.bar.edu, and mumble.edu. RFC 1535 details why this is considered bad practice or even a security hole.
