As part of our ongoing effort to import DNS data into Netbox for automation, we have done a procedure to identify hosts with missing IPv6 DNS entries, with the suspicion that these are potentially sources of problems.
The procedure to produce this data was to look at the PuppetDB `networking` key for the host and select the "primary" IP address for the host, and do a DNS lookup for the FQDN for the host to check for a AAAA record, and report on any missing ones.
Below is a list of the machines (not VMs) without IPv6 DNS grouped by responsible team:
