[dns-operations] DNS Resolution for 93.in-addr.arpa

[Tom Daly]

Hi All,
Perhaps I missed something, but can anyone explain why ns-pri.ripe.net NXDOMAIN's for anything within 93.in-addr.arpa?

tom at admin:~$ dig -4 +norecurse @ns-pri.ripe.net 49.209.184.93.in-addr.arpa PTR

; <<>> DiG 9.4.2-P2 <<>> -4 +norecurse @ns-pri.ripe.net 49.209.184.93.in-addr.arpa PTR
; (1 server found)

Is this expected?
