A Record LookupDNS Tools
IPv4 addresses from a domain's A records, with TTL.
Domain IP Checker
This domain to IP lookup lists every IPv4 and IPv6 address a domain points to, with the PTR name of each address and a note when the addresses belong to a known CDN.
This check runs on our server. The address you enter is used only for this check and is not stored.

How to use the Domain IP Checker
- Enter a domain name, such as
example.com. A full URL is refused, so leave outhttps://and the path. - Leave the resolver on Cloudflare, or switch to Google, Quad9, or Authoritative to ask the domain's name servers directly.
- Once the robot check shows a tick, the Look up button turns on. Press it.
- Each row is one address with its record type, its PTR name if it has one, and its TTL. A CDN note appears above the table when it applies.
How it works
The server sends an A query and an AAAA query for the domain at the same time, to the resolver you picked. A records hold IPv4 addresses and AAAA records hold IPv6 addresses. For every address that comes back, it then asks for the PTR record, which is the reverse DNS name the owner of that address has published.
The CDN note comes from two checks. A PTR name that ends in cloudfront.net marks Amazon CloudFront, and one that ends in akamaitechnologies.com or akamaiedge.net marks Akamai. Cloudflare and Fastly addresses usually have no telling PTR name, so those are matched against the address ranges both companies publish.
The domain and the addresses are used for this check only and are not stored.
Examples
On 3 October 2026, example.com had these two A records:
| Type | Address | CDN range |
|---|---|---|
| A | 104.20.23.154 | Cloudflare 104.16.0.0/13 |
| A | 172.66.147.243 | Cloudflare 172.64.0.0/13 |
Both fall inside Cloudflare ranges, so the page adds a note that the site sits behind that CDN. A domain with no A or AAAA records gets the message "The domain has no A or AAAA records." A name that does not exist at all gets "This domain does not exist."
Limitations
- The addresses are the DNS answer from one resolver. A CDN can give a different set to a resolver in another country.
- Behind a CDN, the address of the server that runs the site is not in DNS, so no lookup of this kind can show it.
- There is no location data. The tool does not guess a city or a country from an address.
- The CDN note covers the four networks above. A smaller CDN, or one that hides its PTR names, gets no note.
- Enter a domain. For an IP address, use Reverse DNS Lookup.
Frequently asked questions
How do I find the IP address of a website?
Enter the domain part of the address, such as example.com, and press Look up. Every IPv4 and IPv6 address in its DNS records is listed.
Why does a domain have more than one IP address?
The site spreads traffic over several servers, or it uses a CDN that answers from many places. Browsers pick one of the addresses.
What is the PTR name next to an address?
It is the reverse DNS name that the owner of that address published. Hosting companies and CDNs often put their own name there, which is why it helps to tell who runs the address.
Can I find the real server behind Cloudflare?
Not with DNS. Cloudflare answers with its own addresses and keeps the origin server's address out of the public records.
