Protocol Comparison
Resolver Consensus vs Registry Truth
Propagation checks show what the internet sees today. DNS reports show what the zone authority publishes — both matter during cutovers.
Methodology: each matrix dimension is written for factual comparability, parser clarity, and operational decision support for domain-intelligence engineering teams.
| Dimension | Propagation probe | Authoritative DNS report |
|---|---|---|
| Question | Do public resolvers agree? | What does the zone publish? |
| Timing | Post-change validation. | Pre-change baseline and audits. |
Implementation guidance
- Baseline with DNS report.
- Validate cutover with propagation checker.
