Registrar & Nameserver Check
Compare the nameservers set at the registry with what the authoritative servers report, and check each server responds correctly.
What this checks
- The delegation published by the parent (registry) zone
- NS records reported by each authoritative server
- Reachability and authoritative answers from every nameserver
- SOA serial agreement across servers
- Glue records and registry status via RDAP
How to read the results
- Pass
- The check succeeded based on the observed responses.
- Warning
- Works now, but is risky, unusual or worth reviewing.
- Fail
- A problem was observed directly in the responses.
- Inconclusive
- Not enough evidence — for example a server did not respond.
