About Domain → IP
Resolve any domain to its IPv4 and IPv6 addresses for debugging, migrations, and allowlisting.
Enter a domain to get its A (IPv4) and AAAA (IPv6) records via DNS-over-HTTPS. Multiple addresses usually mean load balancing or anycast — all are listed, not just the first.
An IP alone rarely identifies the host behind shared hosting or a CDN; pair this with response headers for that. Queries run from your browser.
Where it is used
Confirming DNS cutovers, whitelisting origins in firewalls, diagnosing CDN vs origin issues, and documenting infrastructure.

Frequently Asked Questions
- Why multiple IP addresses?
- Load balancing, anycast, or round-robin DNS. Clients pick one per connection; all listed addresses are valid.
- No IPv6 — is something broken?
- Not necessarily. Many sites still serve IPv4 only. IPv6 absence matters only if your audience is IPv6-only.
- Does the IP reveal the host?
- Roughly — the netblock owner hints at the provider, but shared hosting and CDNs put thousands of sites on one IP.
