A / AAAA Record Lookup

Which IP addresses a hostname points to.

How it works

Find the IP addresses a hostname points to

Type a domain or hostname and we return its A (IPv4) and AAAA (IPv6) records live from Cloudflare's resolver, follow any CNAME alias on the way, and tell you who owns each address: the network, organisation, country and reverse DNS name. Useful when you are checking that a new A record took effect, confirming your site sits behind Cloudflare or a hosting platform, or working out which server a hostname really lands on.

Results appear here after you click Look up addresses.

How this works

1
Query A, AAAA, CNAME
Three parallel DNS-over-HTTPS queries fetch IPv4, IPv6 and any alias for the hostname.
2
Look up address owners
Each IPv4 address is checked against the regional registry for its organisation, network and country.
3
Recognise platforms
Known address ranges reveal Cloudflare, Vercel, GitHub Pages, Shopify, Squarespace and Wix.

Frequently asked questions

What is an A record?: An A record maps a hostname to an IPv4 address such as 203.0.113.10. It is the record browsers use to find your web server. AAAA is the same thing for IPv6 addresses, which look like 2606:4700::1111.
Why does my domain show Cloudflare's IP instead of my server?: When Cloudflare's proxy is enabled, DNS returns Cloudflare edge addresses and traffic is forwarded to your origin privately. That is by design and hides your server from attackers. Turn the proxy off (grey cloud) if you need the real IP exposed.
I changed my A record but this still shows the old IP. Why?: Resolvers cache the old answer until its TTL runs out, often one to twenty-four hours. The remaining TTL shown here tells you how long Cloudflare's resolver will keep the cached value. Lower the TTL before your next change.
Can a domain have more than one A record?: Yes. Multiple A records are called round-robin DNS; clients pick one at random, spreading traffic across servers. It is a simple form of load balancing but does not detect a dead server by itself.
Do I need an AAAA record?: Not strictly, since IPv6-only networks translate to IPv4 automatically. But adding AAAA makes connections from mobile and newer ISPs faster and more direct, and it costs nothing if your host provides an IPv6 address.
