what these files are is a whole lot of lines that look like (broken by me): 18-Apr-2002 16:16:05.491 security: notice: \ denied update from [63.198.141.30].2323 for "168.192.in-addr.arpa" IN by "a whole lot" i mean we've logged 3.3M of these in the last four hours. so who are these people and why are they sending dynamic updates for rfc1918 address space PTR's?
Maybe I'm stupid (it wouldn't be the first time). Why do we bother having "public" nameservers answering for this space at all?Why don't we have "blackhole-[12].iana.org" have A records of "127.0.0.1"? Then, if the local resolver doesn't have authority for that network, it'll loopback to itself looking for the answer (failing just as miserably as it would by beating up on the IANA.ORG servers, but without wasting anyone's bandwidth).
I'm sure there's a reason why we don't already do this (or something similar), but can someone educate me as to why that is?
