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

[Wolfgang Nagele]

Hi Tom,

I had a quick look at this.

 > tom at admin:~$ dig -4 +norecurse @ns-pri.ripe.net 49.209.184.93.in-addr.arpa PTR
 > Is this expected?
At the moment there is no 'domain' object in the RIPE database. This means that 
the holder of this block did not provision any reverse DNS zone for it. So yes, 
NXDOMAIN is the expected behaviour.

Another example is 150.184.93.in-addr.arpa, which has the appropriate 'domain' 
object in the RIPE database. This one works just fine.
