ADVERT
A Record Checker
Fetch IPv4 A records for any domain to verify hosting changes, check propagation, and troubleshoot routing or DNS misconfigurations with IPs at a glance.
How to use this tool
- Enter a domain or hostname and keep record type set to A.
- Run the lookup and review returned IPv4 addresses with TTL values.
- Export or copy the response when documenting DNS changes or incidents.
What you can inspect
- Live IPv4 endpoints returned by the selected resolver.
- TTL values that indicate expected cache expiry windows.
- Authority/additional sections for delegation and NXDOMAIN context.
Operational checks
- Verify apex, www, and API hostnames during migrations.
- Audit round-robin pools and confirm each endpoint remains valid.
- Use TTL timing to plan rollback windows and propagation checks.
FAQ
- Why do I see multiple IPv4 addresses?
- Many domains use round-robin DNS. Validate each address before removing it from rotation.
- How often should I rerun checks after changes?
- Use the returned TTL as a baseline and rerun lookups after that window to confirm fresh resolver answers.
