Can you please explain why your servers are returning NOTIMP for unknown types outside of the range reserved for meta types (128-255)?
The RFC compliant rcode is NOERROR for names that exist and NXDOMAIN for names that do not exist. See RFC3597. % dig @ns1.google.com google.com type1001 ; <<>> DiG 9.15.4+hotspot+add-prefetch+marka <<>> @ns1.google.com google.com type1001 ; (2 servers found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOTIMP, id: 40540 ;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1 ;; WARNING: recursion requested but not available ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ;; QUESTION SECTION: ;google.com.

Is that Google’s intention?
