Thus spake "Jeroen Massar" <[EMAIL PROTECTED]>
What is the point of that? How can a ULA address reach a
global unicast address or for that matter, how is such a ULA
address, which is most likely going to be the sole user of
those reverse servers going to contact any of the root servers,
.arpa servers, RIR servers etc to actually find out where that
server is located in the first place?
...
Also, registered the DNS servers in the global DNS thus means
that those machines will be Internet connected, then what is
the point of ULA again?
The supposed use case for ULA-C is large orgs who interconnect privately
with other large orgs. If you _don't_ allow ULA-Cs in the global reverse
DNS, then every org in the internetwork must hack their local DNS servers to
recognize every other org's reverse DNS entries. That is painful and
unnecessary.
There are operational concerns with putting ULA(-C) addresses in forward
DNS; nobody argues with that. However, putting ULA-C addresses in reverse
DNS harms nobody who can't reach those addresses yet greatly benefits those
that can.
Of course, if everyone just used PI, none of this would be an issue.
