IP Address Lookup
Check the geolocation, ISP, organization and ASN of any IP — or your own. A fast way to verify that your proxy or VPN is actually changing your exit IP.
About this tool
An IP address lookup (or IP geolocation lookup) reveals the public information attached to any IPv4 or IPv6 address: the approximate location it maps to, the internet service provider that owns it, the organization and autonomous system number (ASN) behind it, and the time zone of the region. Every device that connects to the internet does so through a public IP, and that address quietly carries this metadata with every request you make.
How to use this IP lookup tool
Leave the field blank and press Look up to inspect your own current public IP — exactly what websites see when you visit them. To investigate a different address, paste any IPv4 or IPv6 address into the box and run the lookup. Results appear instantly: location, ISP, organization, ASN, coordinates and time zone.
Why check your IP address?
- Verify a proxy or VPN is working. After connecting, your IP and location here should change to the proxy or VPN exit — not your home ISP. If your real ISP still shows, your traffic is leaking.
- Confirm geo-targeting. Running a residential proxy in a specific country? Check that the city and ISP match the location you paid for.
- Investigate suspicious traffic. Look up an IP from your server logs to see which network and country it belongs to.
- Diagnose blocks. Datacenter-hosted IPs are flagged far more often than residential ones; the "organization" and ASN fields hint at why a site may be blocking you.
What the results mean
The ISP and organization identify who operates the address — a home broadband provider, a hosting company, or a proxy network. The ASN is a globally unique number for that network operator. The location is geolocation-database-derived and is approximate (usually city-level), not a precise physical address.
Frequently asked questions
It is a check that returns the public information tied to an IP address — its approximate geographic location, the ISP and organization that own it, the ASN of that network, and the time zone. It does not reveal a person's identity or exact home address.
Just open this tool and run the lookup with the field left blank — it detects and displays your current public IP automatically, along with the location and ISP that websites associate with it.
Connect to your proxy or VPN, then run this lookup. The IP, location and ISP shown should match the proxy/VPN exit, not your real internet provider. If your true ISP still appears, your real IP is leaking.
Geolocation is approximate. Country accuracy is very high, city-level is usually close, but it can be off — especially for mobile networks, VPNs and large ISPs that route traffic through distant hubs. It is an estimate from IP databases, not GPS.
No. The lookup runs from your browser against a public geolocation API and ProxyAxis does not log the addresses you check.
