Many are well aware of the RFC1918 IPs for use on a private LAN.
I just wanted to know it there was an equivalent for DNS - other than
what is documented in RFC-6761
Domains with no NS in the parent zone become harder to discover & get
data about. This is true of any sub-domain in a TLD, but registering a
name for that purpose involves (1) an annual cost & risk this will fail
to be done at some point and (2) finding a registrar who will allow this.
Creating a sub-domain in a domain that was used for something else,
would likely create confusion for future engineers, in a way that (say)
a universally known "unregistered" prefix like "zz--" would not - in the
same way that all network engineers understand the implications when
they see an RFC1918 IP.
If there was already a mechanism, I would find it useful to know about
it. If there isn't, I wanted to express my opinion that I would find it
I meant nothing else.

There can often be information some operating systems automatically put
in their DNS you wouldn't want in the public domain.
