I can't say. I don't know. The people whose eyes I have put this in front of assert we're acting according to the RFC. They're getting tired of my pestering.

The check for "edns aware" involves sending the query with edns extensions. If the reply is formerr (or possibly others?), then you can remember that this server does not understand edns, and repeat the query without it. If you just do the first query without edns, there is no mechanism to then learn that that server does indeed understand edns. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEAREKAAYFAlcifY8ACgkQL6j7milTFsEyTgCfbLe36v3LuECg+Ma4/mjxq52c C9oAnjFeZYZjl2//eCsWM3NvkeWwthUy =H2pv -----END PGP SIGNATURE----- _______________________________________________ mailop mailing list mailop@mailop.org<mailto:mailop@mailop.org> https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop _______________________________________________ mailop mailing list mailop@mailop.org<mailto:mailop@mailop.org> https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop _______________________________________________ mailop mailing list mailop@mailop.org<mailto:mailop@mailop.org> https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop _______________________________________________ mailop mailing list mailop@mailop.org<mailto:mailop@mailop.org> https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
