📡 A Record Checker
Fetch IPv4 A records for any domain to verify hosting changes and troubleshoot DNS issues.
A Record Checker
Resolve IPv4 addresses for any hostname and confirm they point to the correct servers before traffic is routed.
What you'll see
- Live IPv4 endpoints returned by authoritative DNS for the hostname you query.
- Time-to-live values so you know how long resolvers will cache each response.
- Authority section details when records are delegated or missing, helping you spot NXDOMAIN issues.
Common use cases
- Verify a domain is pointing at the right load balancer or web server during migrations.
- Audit round-robin pools and confirm each address is still online.
- Check external DNS before updating firewall or CDN configurations.
DNS Resolver
Find the IPv4 address (A record) for any domain. Great for server migrations, troubleshooting, and DNS validation.
Prepared query:
example.comTroubleshooting tips
- Query both the apex domain and common subdomains such as www or api to reveal mismatched records.
- Note the TTL so you can estimate when cached responses at ISPs will expire after a change.
- Follow up with an actual ping or traceroute to confirm routing once the correct IP is returned.
FAQ
- Why do I see multiple IPv4 addresses?
- Many domains use round-robin DNS. Check each IP for availability before removing it from the pool.
- How often should I recheck records after a change?
- Use the TTL to estimate propagation. Re-run lookups once cached entries at providers are expected to expire.
