Website IP Lookup
Resolve any domain name to its IP address and get helpful network context like location, ISP, ASN, and hosting clues for the returned IPs.
Resolve domains to IPs in seconds.
Helpful when checking hosting or network ownership.
See where a website appears to be hosted.
What this website IP lookup shows
This tool resolves a domain to its visible IP addresses and adds useful network context so you can better understand where a website appears to be hosted.
That makes it useful for developers, support teams, marketers, security research, and anyone checking hosting setup or verifying DNS changes.
Why it matters
Website IP data helps explain where traffic is going, which network appears to host the site, and whether multiple endpoints are involved.
Why does a domain resolve to multiple IPs?
Large websites often use round-robin DNS or Anycast routing, returning multiple A records. Each IP may point to a different server or data centre for load balancing and redundancy.
CDN providers like Cloudflare or Fastly often return an IP close to the requester's location — so the IP you see may differ from someone in another country.
What is an ASN?
An ASN (Autonomous System Number) identifies the network that owns and routes traffic for a given IP range. From the ASN you can tell whether a site is hosted on AWS, Cloudflare, Google Cloud, a specific ISP, or any other network operator.
Understanding A records and AAAA records
An A record maps a domain name to an IPv4 address (e.g. 192.0.2.1). An AAAA record maps a domain to an IPv6 address (e.g. 2001:db8::1). Modern websites often have both to support older and newer clients.
This tool returns both A and AAAA records if available. IPv6 adoption is growing but IPv4 is still dominant for most websites.
CDN and geolocation routing
CDN providers like Cloudflare, Fastly, and Akamai use geolocation-based routing. They return different IP addresses depending on where the request originates. A user in Europe may get a different IP than a user in Asia, even for the same domain.
This tool performs a lookup from a central location, so the IP returned may differ from what users in other regions see. For truly accurate results, use our DNS lookup tool with a specific DNS resolver located closer to your target region.
Key hosting data explained
LocationThe geographic location (country/city) where the server's IP is registered. Based on IP geolocation databases.
ISPInternet Service Provider — the company providing network connectivity. Helps identify the hosting provider.
ASNAutonomous System Number — uniquely identifies the network operator (e.g. AS16509 for AWS).
IPv4/IPv6Two versions of the IP protocol. IPv4 uses 32-bit addresses (billions available). IPv6 uses 128-bit addresses (virtually unlimited).
Why check website IP?
- Identify hosting provider — know if a site uses AWS, Cloudflare, Linode, or dedicated hosting.
- Verify DNS changes — confirm a domain points to the correct IP after migration.
- Check geolocation — see where a server is located and whether it uses CDN acceleration.
- Security research — investigate suspicious websites by tracing their hosting.
- Network troubleshooting — diagnose connectivity issues by identifying the hosting infrastructure.
Frequently asked questions
Why do I see multiple IPs for one domain?
That is normal for load balancing, CDNs, redundancy, and mixed IPv4 or IPv6 setups.
Is the IP the same for everyone?
Not always. CDNs and geolocation routing can return different IPs depending on region.
Can I tell if a site uses Cloudflare?
Often yes, especially when the returned network or ASN points to Cloudflare-related infrastructure.
How is this different from IP Lookup?
Website IP Lookup starts with a domain name, while IP Lookup starts with an IP address you already know.
