See http://www.isi.edu/~faber/FAQ.html#SIG so... the point i was tryig to make was/is: simple queries only help if you know: ) the version of software running on your caching server and ) the search list defined by your "resolv.conf" zig.usc.edu, boreas.isi.edu, luna-base.org, ep.net, lcs.mit.edu, comcast.net, all run slightly different caching code and variable search lists. you, me, Ted, Keith, John, et.al. are going to see -slightly- different responses when presenting our individual local caching servers with non-terminated DNS strings. Japp and Karl both hinted at this problem - local policy is the worst policy, except for all the others. Your local DNS admin can (and occasionally they do) toss you into a random walled-DNS garden that has only a passing similarity to what you think of as the "Internet". http://www.icann.org/committees/security/sac032.pdf is illustrative. -- --bill Opinions expressed may not even be mine by the time you read them, and certainly don't reflect those of any other entity (legal or otherwise). _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
