IP Address Lookup
Paste a public IPv4 or IPv6 address, or leave the field blank to use the IP seen by this request. The lookup returns approximate network-level location, IP type, ISP, ASN, organization and timezone. Use it to sanity-check firewall or WAF rules, review analytics spikes and understand which public network a log entry points to.
How to look up an IP address
-
1
Enter a public address
Use IPv4 (`8.8.8.8`) or IPv6 (`2001:4860:4860::8888`). Compressed IPv6 forms are accepted.
-
2
Use the detected IP if needed
Leave the field blank, or choose the detected-IP option in the funnel, to query the public IP seen by this request.
-
3
Review the fields
Read the country, region, city, latitude/longitude, ISP, ASN, organization, IP type and timezone.
-
4
Interpret it cautiously
Treat city and coordinates as approximate. VPNs, proxies, mobile gateways, CGNAT and cloud edges can move the apparent location.
What the lookup can and cannot tell you
| Field | What it means | How to read it |
|---|---|---|
| IP address | The normalized address returned by the lookup | Exact for a valid public IP |
| Type | IPv4 or IPv6 | Exact for a valid address |
| Country | Country inferred for the public network | Usually the most reliable location field |
| Region / city | Subdivision and city associated with the network | Approximate, often an ISP hub or edge point |
| Latitude / longitude | Coordinates for the estimated network location | Not GPS, not a device position |
| ISP | Internet provider or network operator | Good clue for routing and support triage |
| ASN | Autonomous System Number announcing the route | Useful for grouping traffic by network |
| Organization | Organization associated with the connection | May be an ISP, host, cloud provider or customer label |
| Timezone | Timezone inferred from the estimated location | Useful for log review, but still approximate |
Public and special-use IPs
Public internet lookups work best for globally routable addresses. Private, loopback, link-local, documentation and carrier-grade NAT ranges are reserved or special-purpose, so they often have no meaningful public geolocation.
| Range example | Typical use |
|---|---|
10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 |
Private LAN addresses |
127.0.0.0/8 |
Loopback on the same device |
169.254.0.0/16 |
Link-local fallback addressing |
100.64.0.0/10 |
Carrier-grade NAT shared address space |
192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24 |

What IP geolocation cannot do
- Find a person’s home or device. IP geolocation points to network data, not GPS, billing records or a physical address.
- Prove who used a shared IP. NAT, CGNAT, public Wi-Fi, mobile carriers and corporate proxies can place many users behind one public address.
- Reliably classify every VPN or proxy. Known VPN or cloud networks may be visible in the ISP, organization or ASN fields, but residential proxies can look like ordinary access networks.
Legitimate uses
- Analytics debugging: see whether a traffic spike comes from one ASN, ISP or country.
- Firewall / WAF tuning: confirm a rule targets the expected country, ISP or public network.
- Support triage: compare the IP a service sees with the network a user expected to use.
- Threat-intel enrichment: add ASN, provider and country context to suspicious logins.
Common mistakes
- Treating city-level coordinates as a precise user location.
- Confusing the ISP, organization or ASN with the individual using the connection.
- Blocking a whole ASN or country without checking for legitimate users and false positives.
- Using IP geolocation alone for fraud or access decisions.
Frequently Asked Questions
Country is usually more reliable than city or coordinates. City-level results can point to an ISP point of presence, mobile gateway, VPN exit, proxy or cloud edge rather than the user’s exact location.
Yes. Leave the field blank or choose the detected-IP option, and the tool queries the public IP your current connection presents. If you are behind a VPN, it usually shows the VPN exit node.
No. The lookup returns network-level fields for a public IP address. It does not reveal a name, home address, device location or the individual user behind a shared connection.
It can show a known VPN, hosting provider or cloud network in the ISP, organization or ASN fields, but it is not a dedicated VPN/proxy detector. Residential proxies and some mobile networks can look ordinary.
