In the latter case, keep in mind that, while using public resolvers for (say) surfing or the like, when it comes to mail routing and DNS list checking you *must* use your own recursive (no forwarding to external DNS !) full resolver; also, and since we're at DNS, ensure that your firewall allows both UDP *and* TCP traffic toward port 53 of whatever external DNS host (this is also needed if you run an internal resolver) *AND* ensure that UDP packets above 512 bytes (used by EDNS) won't be dropped by some dumb firewall rule ------------------------------------------------------------------------------ Monitor Your Dynamic Infrastructure at Any Scale With Datadog!
