Depending on what software you're using, it may be possible to work
around this by using another DNS domain.  With Asterisk, for instance,
the enum.conf file allows you to specify one or more domains to be
searched in addition to e164.arpa -- the example given in the file is
e164.org, but you could easily use a local subdomain.

Otherwise, you might just have to write some Lua code to handle the
lookups for you.  For examples of how to do this in the recursor, see

Hmm.  Might it also work to do something really simple involving more
than one recursor?  If the primary recursor had something like this:


...and the one at then had:


...with being the local "authoritative" server for e164.arpa,
might then a number end up first being looked up on, and then,
if that failed, using  I guess it's possible that
would need a Lua hack to transform a NXDOMAIN into some sort of failure,
to cause the primary recursor to go to (or a third local
recursor, if you prefer, of course).

Could someone who knows more about this than I do tell me how far into
the wrong ball park I am with this stuff?  :)
