What this means

DNS-provider inference is derived from visible nameserver and DNS patterns. Provider concentration does not establish service quality, resilience, organisational dependency or endorsement. Nameserver and provider movement may reflect planned migration, supplier change, portfolio consolidation or routine administration.

About this view

Where is authoritative DNS visibly concentrated, how diverse are the nameserver arrangements, and where has delegation or inferred DNS-provider responsibility moved?

Show the visible distribution of authoritative DNS providers and nameserver arrangements, together with observed delegation and DNS-provider movement during defined observation windows.

Published limitations

  • Derived from public .auDO observations generated from the canonical observatory dataset.
  • Counts describe the observed .auDO panel, not the whole .au namespace.
  • Missing optional fields are counted as missing rather than inferred.
  • DNS provider inference is based on visible public DNS patterns.
  • Provider concentration does not imply endorsement, service quality, dependency risk or organisational fault.
  • Nameserver or provider movement may reflect normal operational change.

Data quality and availability

  • Required public event scope: observatory.
