Definitely true. Having said that, different software behaves differently (as we run multiple different software packages, I see differences across our deployment even). Note that although this should be done, the specification mandating this is from September of last year so the software hasn't likely caught up yet. Though there is some argument that RFC1034 said this too, but less well stated. I'll further note that this is not a root specific problem. This is likely true across the deployed DNS ecosystem, but the root does serve as a good test case. -- Wes Hardaker USC/ISI _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations
