Domain to IP Lookup

Resolve any domain name to the IPv4 and IPv6 addresses serving it, each annotated with its hosting provider, network (ASN) and approximate location.

About Domain to IP Lookup

A domain-to-IP lookup performs the same DNS resolution your browser does before it can reach a website, but it shows you the raw result. When you enter a domain, this tool queries the Domain Name System for its A records (IPv4 addresses) and AAAA records (IPv6 addresses) and lists every address it finds. A single hostname often maps to several IPs: sites behind load balancers, content delivery networks or anycast routing advertise multiple addresses so traffic can be spread across servers and regions.

For each address returned, the lookup adds context you cannot get from a plain DNS query: the country and city the IP is geolocated to, the autonomous system number (ASN) it is routed under, and the organisation that owns that network block, typically the hosting company, cloud provider or CDN. This turns a bare list of numbers into a picture of where and with whom a site is actually hosted.

The query runs on our EU-based servers, so the result reflects DNS as seen from a neutral European vantage point rather than whatever your local router or ISP resolver returns. One caveat worth understanding: if a domain sits behind a reverse proxy or CDN such as Cloudflare, Fastly or a cloud load balancer, the IP you see belongs to that provider's edge network, not the origin server. That is by design, and it is why a small business site may report an IP owned by a large infrastructure company.

Geolocation of an IP address is approximate. It reflects where the network operator has registered or announces the address, which is usually the data-centre region rather than a precise street address, and it can differ from where the company behind the site is based.

How to use it

  1. 1Type or paste a domain name (for example example.eu) into the input field, without http:// or a path.
  2. 2Submit the form to resolve the domain on our EU servers.
  3. 3Read the results table: each row is one IP address with its geolocation and the hosting or network provider that owns it.
  4. 4Note whether addresses are IPv4 (dotted decimal) or IPv6 (colon-separated hex), and whether several IPs are returned for redundancy.
  5. 5If the owner shown is a CDN or cloud provider, treat the IP as an edge or proxy address rather than the true origin server.

Common use cases

  • -Confirming where a website is hosted and which provider or cloud region serves it before a migration or audit.
  • -Checking DNS propagation after moving a site to a new server or changing A/AAAA records.
  • -Verifying that a domain has working IPv6 (AAAA) connectivity, not only IPv4.
  • -Investigating unfamiliar domains during security or abuse triage by identifying the network and ASN behind them.
  • -Detecting whether a site sits behind a CDN or reverse proxy versus being served directly from an origin host.

Frequently asked questions

What is a domain to IP lookup?
A domain to IP lookup resolves a human-readable domain name into the numerical IP addresses that computers use to route traffic to it. It queries DNS for the domain's A (IPv4) and AAAA (IPv6) records and returns every address that answers for that name.
How do I find the IP address of a website?
Enter the website's domain name into a domain-to-IP tool and it returns the IPv4 and IPv6 addresses from the domain's DNS records. This lookup adds the hosting provider, network ASN and approximate location for each address so you can see who serves the site.
Why does one domain have several IP addresses?
Multiple IPs usually mean the site is designed for redundancy and scale. Load balancers, CDNs and anycast networks publish several A or AAAA records so requests can be distributed across servers or data centres, improving availability and performance.
Why does the IP belong to Cloudflare or a cloud provider instead of the real server?
When a site uses a CDN or reverse proxy, DNS points to that provider's edge network rather than the origin server. The IP you see is the proxy's address, which shields and accelerates the real backend; the origin IP is not exposed in DNS.
How accurate is IP geolocation in this tool?
IP geolocation identifies the region or data centre where an address is registered or announced, not a precise physical location. It is reliable at the country and provider level but should not be read as the exact address of the company behind the site.
What is the difference between the IPv4 and IPv6 addresses shown?
IPv4 addresses come from the domain's A records and use the familiar dotted-decimal format such as 203.0.113.10. IPv6 addresses come from AAAA records and use longer colon-separated hexadecimal notation; a domain can have either, both or neither.
