After a routing issue between us and an instance of the RFC1918
anycast servers blackhole-[12] which caused all sorts of bizzare
failures within customer networks, I'm trying to figure out if
there is a really good reason why I shouldn't keep a copy of the
1918 zones on my local recursive customer-facing DNS servers so
breakage between us and these servers won't cause grief in the
future.  So my questions are:  1) Is there a good reason why I
shouldn't host a local copy of the RFC1918 in-addr zones on my
servers?  2) I've dug around and haven't been able to find an
example of a RFC1918 zone file ala what's on the official
servers.  I'm assuming that these are basically just empty
domain filas but I'd love to verify that this is the case.   Of
course, the blackhole servers I tried don't respond to AXFR.  3)
Alternatively, I could host a local anycast instance of these
servers, but I
