Focused DNS testing, without the noise.
testing-dns.com provides practical DNS validation utilities for engineers and security teams. Verify resolution, record configuration, and delegation behaviour with clarity and intent.
Resolution testing
Confirm that domains resolve as expected across common record types (A, AAAA, CNAME) and identify obvious resolution failures.
Record posture
Inspect record presence and targets to catch typos, stale entries, and unintended configuration drift.
Delegation checks
Validate NS configuration and delegation paths to identify common zone and registrar misconfigurations.
Propagation awareness
Gain basic visibility into DNS propagation behaviour during changes, migrations, or incident response.
Pre‑launch validation
Use DNS checks as part of readiness reviews before production cutovers or public launches.
Security hygiene
Identify obvious DNS misconfigurations that can impact availability, trust, or security posture.
