| Subject: | Add "DDNS check-only" option for handling the TXT or DHCID guard RRs |
This is associated with ticket #42620: Add "DDNS solo" option for operation of v4/v6 with prerequisites that ignore the other v6/v4 RRs and it introduces another perspective/use case from a production environment.
Quoting the actual request:
"This week we received a request from a customer to implement what they called a 'check only' method.
They are only concerned with dynamic records overriding static records (which must be prevented) and they don't care if dynamic records get 'hijacked'.
They suggested that the TXT record value should not be checked in this method, but only if it exists or not.
If it exists, then it is a dynamic record and it can be overwritten.
If it does not exist, then this record is static and can't be updated.
Their use case is for users that roam between shared docking stations."
