1. DNS/RFC/8906/remediation

について、ここに記述してください。

Domain registrants who do not maintain their own DNS infrastructure are 
  entitled to a DNS service that conforms to standards and interoperates well.  

Registrants who become aware that their DNS operator does not 
  have a well-maintained or compliant infrastructure should insist that 
  their service provider correct issues and switch providers if they do not.
