Other than DNSSEC, I'm aware of these relatively simple hacks to add entropy to DNS queries. 1) Random query ID 2) Random source port 3) Random case in queries, e.g. GooGLe.CoM 4) Ask twice (with different values for the first three hacks) and compare the answers I presume everyone is doing the first two. Any experience with the other two to report? R's, John
