Hi,
are there some people experiencing issues on some AS when using
iana blackhole nameservers for localnets?

I usually meet this response for instance:
dig 172.16.1.1 @blackhole-1.iana.org
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 34667
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1
;; WARNING: recursion requested but not available

;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 4096
;; QUESTION SECTION:
;172.16.1.1.                    IN      A

;; Query time: 46 msec
;; SERVER: 192.175.48.6#53(192.175.48.6)
;; WHEN: Thu Oct 27 16:


But I don't get any reply packet on AS8220 (COLT).
dig 172.16.1.1 @blackhole-1.iana.org
;; global options: +cmd
;; connection timed out; no servers could be reached

thank you.
