Note: DNAME is equivalent to RFC 2317. In both cases this
will break the customers expectation that they can just use
x.y.z.in-addr.arpa for the PTR records.
Note for reliable local reverse lookups when the external
link is down they will need to slave the ISP's x.y.z.in-addr.arpa
zone and well as manage the zone the CNAME / DNAME maps to.
