windows server 2016 - What is Wrong with My Reverse Lookup PTR Record

I can't figure out why my PTR record does not work on my new server. This configuration worked on my old server and I already confirmed with my host that they added a record on their end so that 72.164.185.in-addr.arpa points to serer.copblaster.com but whenever I do a rDNS check of IP address 185.164.72.225 on MxToolBox or anything else it says no PTR record found.



As my screenshot clearly shows I have a basic reverse lookup zone with PTR record setup properly.



enter image description here




UPDATE: Does this info help at all?



C:\WINDOWS\system32>nslookup -debug -d2 -type=PTR 185.164.72.225
