A Record Lookup
Look up the A (IPv4) and AAAA (IPv6) records of a domain or subdomain: the addresses browsers and mail servers actually connect to.
What the A Record Lookup shows
An A record maps a name to an IPv4 address; an AAAA record does the same for IPv6. Browsers, mail servers and APIs connect to these addresses, so this is the record that decides where a domain actually points.
The lookup asks public resolvers for both, so it shows what visitors see now, with the TTL that tells how long resolvers may keep the answer. If the name is an alias, the resolver follows the CNAME and returns the addresses at its end.
Other single-record lookups: TXT Lookup, CNAME Lookup, SRV Lookup, MX Lookup. Paste any record into the DNS Record Explainer for a plain-English breakdown.
Frequently asked questions
How do I find the IP address of a domain?
Enter the domain above. The A record gives its IPv4 address, the AAAA record its IPv6 address. From a terminal: dig A example.com @1.1.1.1, nslookup example.com, or ping example.com for the first address only.
Why does my domain show several IP addresses?
Large sites and CDNs publish several A records for load sharing and failover; clients pick one. Different answers from different places are normal for geo-routed CDNs such as Cloudflare or CloudFront.
I changed my A record - why do I still see the old IP?
Resolvers keep an answer until its TTL expires, and the TTL that counts is the one on the old record. Wait that long and look again; the DNS Propagation checker shows which resolvers around the world have the new address.
Do I need an AAAA record?
No, IPv4 alone works everywhere. Add AAAA only if your server really answers on IPv6 - a wrong AAAA record breaks the site for IPv6 users, who try it first.
Who owns the IP address a domain points to?
Run a Reverse DNS lookup on the address for its PTR name, which often names the host (a cloud provider or CDN). The WHOIS of the IP block names the network that owns it.
