I assume that 5.12.11.in-addr.arpa.zone is the name of the *file* and
5.12.11.in-addr.arpa is the name of the zone.

/etc/hosts is not used by DNS, so it's irrelevant.  What do the
"nameserver" directives in /etc/resolv.conf say?

Based on what you've said, things seem OK.  What specific errors do you get
when you try to do reverse resolution?

I presume we can't access these servers from the Internet, so we can't test
them directly, right?
