How accurate is the IP geolocation?

IP geolocation identifies the country and region with high accuracy (95%+), but city-level data can be off by tens of kilometers. ISP and ASN data are highly accurate. The location reflects where the ISP routes the IP, not necessarily the physical device location.

An ASN (Autonomous System Number) is a unique identifier assigned to a network operator — an ISP, hosting provider, or large organization. ASNs are used to coordinate IP routing on the internet. For example, AS15169 belongs to Google LLC.

Can I look up any IP address?

You can look up any public IPv4 address. Private addresses (like 192.168.x.x, 10.x.x.x, or 172.16–31.x.x) cannot be geolocated — they are reserved for internal networks and not routed on the internet.

Is my IP address stored or shared?

No data is stored by Sprytools. The lookup is made directly from your browser to the ip-api.com service. The result is displayed locally and never saved.

What is the difference between ISP and organization?

ISP is the Internet Service Provider that assigns the IP. Organization is the entity that has registered the IP block — often the same as the ISP, but can differ for large companies that own their own IP ranges (e.g. Google, Cloudflare, Amazon).

IP Address Lookup — Find Location, ISP & ASN

Look up any IPv4 address to find its geolocation, Internet Service Provider (ISP), Autonomous System Number (ASN), and timezone. The tool automatically detects your own IP on load — or enter any public address to investigate it.

What Information Does an IP Address Reveal?

An IP address is the numerical label assigned to every device on a network. When you connect to the internet, your ISP assigns you an IP from a block they control. That block is registered with global databases that associate it with a geographic region, an organization, and a network identifier (ASN).

This lookup returns:

Country, region, city — the approximate geographic location of the IP registration
ZIP / Postal code — available for many addresses in the US and Europe
Coordinates — latitude and longitude, with a link to view the location on OpenStreetMap
Timezone — the IANA timezone for the IP’s registered region
ISP — the Internet Service Provider that controls the IP block
Organization — the entity registered as the owner of the IP range
ASN — the Autonomous System Number, a unique identifier for the network operator

IP Geolocation Accuracy

IP-based geolocation is highly accurate at the country level (95%+). Region and city data is less precise — the result shows where the ISP’s infrastructure is registered, which may differ from the physical device location by tens or even hundreds of kilometers. Mobile IP addresses often geolocate to the ISP’s city headquarters rather than the user’s actual location.

For VPNs and proxies, the lookup shows the location of the VPN exit node, not the user’s real location. This is a common use case for developers testing geo-targeted content.

What Are ASNs?

An Autonomous System (AS) is a collection of IP networks under unified administrative control. Each AS is identified by an ASN (Autonomous System Number), assigned by regional internet registries (RIPE, ARIN, APNIC, etc.). ASNs are used to coordinate routing between ISPs on the internet’s backbone.

Examples:

AS15169 — Google LLC
AS13335 — Cloudflare, Inc.
AS16509 — Amazon.com, Inc.
AS3320 — Deutsche Telekom AG

When you see the same ASN across many IP addresses, they all belong to the same network operator.

Private and Reserved IP Addresses

Not all IP addresses can be geolocated. The following ranges are reserved for internal networks and will not return geolocation data:

Range	Use
10.0.0.0/8	Private (RFC 1918)
172.16.0.0–172.31.255.255	Private (RFC 1918)
192.168.0.0/16	Private (RFC 1918)
127.0.0.0/8	Localhost (loopback)

These addresses are only routable within local networks and do not appear on the public internet.

Privacy

This tool makes a direct request from your browser to ip-api.com for geolocation data. No IP addresses or lookup results are stored by Sprytools. The data returned is publicly available information from IP registry databases — it does not reveal personal information beyond what is associated with the IP’s network registration.
