Comment 3 for bug 1746627

Sorry been a while since I reported this and memory fading but it looks like you're unsetting the PTR manually and not replicating the bug?

The bug is that if I release a floating IP from my project then I'd expect the PTR record to also be deleted.

What if you change your steps to:

openstack ptr record list <-------------------- Nothing shown
openstack floating ip create public
openstack server add floating ip INSTANCE_NAME_OR_ID FLOATING_IP_ADDRESS
openstack ptr record list <-------------------- one record shown
openstack ptr record set FLOATINGPOINT_ID ftp.example.com.
openstack server remove floating ip INSTANCE_NAME_OR_ID FLOATING_IP_ADDRESS
openstack floating ip delete FLOATING_IP_ADDRESS
openstack ptr record list <-------------------- Still shown?
