After a routing issue between us and an instance of the RFC1918 anycast servers blackhole-[12].iana.org 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 can think of lots of good reasons why this might be bad. Ideas? Comments? --forrest
