Server Location Checker
Enter a domain and this checker resolves it to an IP address and cross-references a GeoIP database to return the city, country, region, timezone, ISP and ASN (Autonomous System Number). When a CDN or cloud provider like Cloudflare or Fastly fronts the site, its name usually appears in the ASN or organisation field, so you can often tell at a glance.
How the lookup chain works
-
1
Enter the domain
Just the hostname (`example.com`); www and bare variants are both resolved.
-
2
DNS resolves to an IP
The hostname is resolved to its IP address with a standard DNS lookup.
-
3
ASN and GeoIP are queried
The IP maps to an Autonomous System (e.g., AS13335 Cloudflare) and a MaxMind-style city database gives an approximate location.

Read the location and network
The result shows the country, city, coordinates, timezone, ISP and ASN/organisation, plus a map link. A CDN or proxy shows its edge network in the ASN name, not the real origin server.
What you can and cannot learn
| Signal | Can find out? |
|---|---|
| Edge IP that served the response | Yes, always |
| Country and city of the edge | Yes, within ~50km |
| CDN / cloud provider | Yes |
| Origin server IP (behind CDN) | No, usually hidden |
| Server software (nginx, Apache) | Sometimes (Server header) |
| Physical datacenter address | Rough region only |
Common providers and how they appear
- Cloudflare, AS13335, any of 280+ edge cities, IPs in 104.16.0.0/12, 172.64.0.0/13, etc.
- AWS CloudFront, AS16509, globally distributed, IPs rotate;
Viaheader often mentions CloudFront. - Fastly, AS54113, 60+ POPs, IPs in 151.101.0.0/16.
- Google Cloud CDN, AS15169, TLS SAN often lists the GCP project ID as a subdomain.
- Akamai, AS16625 / AS20940, very fragmented;
Server: AkamaiGHostheader is the giveaway.
Why the location can feel wrong
A domain may resolve to a datacenter thousands of km from the business that runs it. Reasons: the origin is in one region but a CDN edge fronts every country; the host leases racks globally under a single ASN; a VPN-style proxy relays traffic. GeoIP is an approximation of the IP routing, not a statement about the company behind the site.
Ethics note
Knowing where a site is hosted is public information, routing data has to be exchanged for the internet to work. Using that data to target individuals or infer sensitive info about specific users is not fair game. Use it for SEO, infrastructure auditing, or troubleshooting latency.
Frequently Asked Questions
Not from a DNS lookup alone. If the origin IP has ever been exposed (historical DNS records, direct certificate issuance on the origin, SSH banners on ancillary services), third-party databases may surface it. This tool does not attempt origin discovery.
City-level accuracy is roughly 55-80% depending on the provider and the IP range. Country-level is usually 99%+. Accuracy is worse for mobile and VPN ranges.
No. A business can host on a reseller (WP Engine, Kinsta) whose underlying ASN belongs to GCP or AWS. The ASN shows the physical network operator, not the brand you bought hosting from.
Autonomous System Number, the identifier for a network that participates in BGP routing. Every IP on the public internet belongs to an ASN. AS numbers are assigned by regional registries (ARIN, RIPE, APNIC, etc).
