After all, the DNS would work as well without caches. "NXDOMAIN cut" is not purely an internal optimization because it changes the observable behavior of a resolver.

It is not just a matter for the implementer. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
