Nope.  RFC2006 is "The Definitions of Managed Objects for IP Mobility
Support using SMIv2".

*SKIP*

You are talking about RFC2606 "Reserved Top Level DNS Names".  No,
neither resolving nor serving across the fence was ever a point of this
endeavour.

Also, RFC6761 "Special-Use Domain Names" -- is worth reading.  Just
spotted this gem (in support of The Endeavour)

	5.  Authoritative DNS servers SHOULD recognize these names as
	special and SHOULD, by default, generate immediate negative
	responses for all such queries, unless explicitly configured by
	the administrator to give positive answers for private-address
	reverse-mapping names.

Also, doesn't mention 127.in-addr.arpa. .  Quality?

Totally resolvable.  IP is 199.43.135.53 .

*CUT*

Torvalds' goal for Linux is very simple: World Domination
Stallman's goal for GNU is even simpler: Freedom
