What Is My IP Address
Check your public IP address instantly. View ISP, ASN, location, IPv4/IPv6 and network details with the IPOK IP lookup tool.
What This IP Tool Shows
Your public IP address is the internet-facing address that websites and online services see when you connect. It is different from the private IP address assigned by your router on your local network.
This page also displays supporting network context such as ISP name, ASN, and approximate location so you can validate which network path your traffic is actually taking.
If you are troubleshooting, capture the IP value and compare it with logs from your VPN client, firewall, or application server to confirm that the same address is observed end to end.
Public IP vs Private IP
A public IP is shared by your network to the broader internet, while private IPs identify devices inside your home or office network. Your router uses NAT to map many private devices to one public IP.
Understanding the difference matters when troubleshooting. If a site reports a different public IP than expected, the issue is external routing, not your device’s local IP configuration.
ISP and ASN Context
The ISP field shows the organization providing your internet access, while the ASN indicates the autonomous system that advertises the IP range on the global routing table.
ASN data helps diagnose corporate gateways, hosting providers, or VPN exits. If the ASN does not match what you expect, you are likely exiting through a proxy, VPN, or shared network.
IPv4 and IPv6 Coverage
Many networks are dual stack, meaning you can have both IPv4 and IPv6 connectivity. Some VPNs only tunnel IPv4, leaving IPv6 exposed and causing leaks.
If you see different IP families across tools, check whether your VPN supports IPv6 or temporarily disable IPv6 at the OS level while you troubleshoot.
VPN and Proxy Verification
After connecting to a VPN, your public IP should reflect the VPN exit location and ISP. If it still shows your home ISP, the tunnel is not active for this browser session.
Split tunneling can intentionally route some traffic outside the VPN. If one tool shows the VPN IP and another shows your ISP, you likely have a partial tunnel or browser-specific proxy settings.
Why Location Is Approximate
IP geolocation is based on routing announcements, ISP records, and public databases. It is usually accurate to the country level, but city-level accuracy can vary.
Large ISPs often route traffic through centralized gateways or CGNAT, which can place your visible IP in a nearby region even if you are elsewhere.
Use Cases and Troubleshooting
IP lookup helps explain geo-blocks, pricing differences, login challenges, or sudden CAPTCHA prompts. If a service sees you in the wrong region, the IP page is the first signal to confirm.
It is also useful when configuring allowlists or debugging API access. Many systems restrict access by IP, so confirming the exact egress IP prevents trial-and-error whitelisting.
Privacy and Safe Sharing
Your IP is not your identity, but it is a stable network identifier. Avoid sharing the full IP publicly unless necessary, and mask the last octet when posting logs.
If you rely on VPN privacy, enable kill switch features and retest after sleep or network changes to ensure the tunnel remains active.
Shared IPs and NAT
Many households, offices, and mobile carriers use a shared public IP for hundreds or thousands of users. This is normal and does not mean your traffic is being intercepted.
Carrier-grade NAT and enterprise gateways can make many devices appear as one IP. If you see a shared IP, focus on whether the country and ASN are correct rather than expecting a unique address.
When Results Change
IP addresses can change when you move between Wi-Fi and mobile data, reboot a router, or when your ISP rotates leases. Sudden changes do not always mean a leak.
If you see frequent shifts within minutes, check for unstable VPN connections or multiple active network interfaces. Disable unused adapters to stabilize results.
Combine with Other Tests
IP lookup is most valuable when compared with DNS and WebRTC tests. All tools should agree on the visible country and provider if your privacy setup is working.
If DNS or WebRTC shows a different location, you likely have a partial leak. Use those results to decide whether to adjust VPN settings or browser privacy controls.
Security and Operations
Security teams use egress IPs to build allowlists for APIs, corporate apps, and internal dashboards. A verified IP reduces downtime caused by blocked traffic.
For incident response, knowing the exact egress IP helps correlate logs across CDNs, WAFs, and application servers. It is a foundational signal for debugging access incidents.
CDNs, Proxies, and Privacy Relays
Some browsers and devices use privacy relays or built-in proxy services that route traffic through third-party networks. These features can replace your ISP IP with a relay IP even if you are not using a VPN.
If you use a corporate proxy or CDN-based forwarder, the IP shown here may represent that proxy rather than your device. This is expected, but you should document the proxy IPs for allowlists.
When in doubt, disable those features temporarily to confirm your baseline IP before re-enabling them.
