About IP Lookup

IP Lookup shows the public IP address that wetool.site observes from your request, which is useful for checking egress IP, VPN, proxy, or corporate network routing.

The result may be IPv4 or IPv6, and it may represent a NAT, CDN, ISP gateway, or enterprise proxy exit.

How to use IP Lookup

Open the tool page; on production it calls the same-origin /api/ip endpoint.
Read the returned public IP and copy it for operations, allowlists, or debugging notes.
Refresh after changing VPN, proxy, or network settings to compare egress changes.

When you would use it

Request an API, database, or firewall IP allowlist.
Confirm whether a VPN, proxy, cloud desktop, or company gateway is active.
Compare server log remote address values with your browser’s observed exit IP.

Public IP, proxies, and server observation

This tool does not read a local network adapter address in the browser. It displays the address observed by the wetool.site server when your request reaches it. Nginx, CDN, reverse proxy, VPN, NAT, and IPv6 preference can all affect the result. Private LAN addresses usually are not visible to websites.

IPv4 looks like 203.0.113.42; IPv6 looks like 2001:db8::1.
The same device can show a different egress IP after changing networks.
A corporate proxy can make many users appear as the same public IP.
If a CDN sits in front of the site, the backend must pass the real client address correctly.

IP Lookup FAQ

Why is it not my computer’s LAN IP?: A website normally sees the public egress address used to reach the server, not your 192.168.x.x or 10.x.x.x private address.
Why did my VPN not change the IP?: The browser may not be using the VPN, traffic may be split by DNS or proxy rules, or this site may be reached through another route.
Does this expose my IP?: Any website request exposes a source IP to the server. This tool simply shows you the value observed by the same-origin /api/ip endpoint.

IP Lookup vs geolocation

An IP address can only roughly indicate a network exit. It does not reliably identify a person or device. Country, ISP, and ASN enrichment require separate databases; this tool currently shows only the server-observed address.

Public IP, private IP, and NAT differences

This tool shows the public egress IP seen by wetool.site, not necessarily the LAN address on your device.

Addresses such as 192.168.x.x, 10.x.x.x, and 172.16-31.x.x are private network addresses and usually do not appear in public web requests.
Corporate networks, carrier CGNAT, VPNs, and proxies can make many devices share one public egress IP.
If the result differs from local network settings, check VPN, proxy, mobile hotspot, and browser network configuration first.

IP lookup privacy boundary

An IP address is naturally exposed by a network request, but it is not a precise identity or exact location.

wetool.site /api/ip only returns the request source IP and does not require an account or input content.
A public IP may identify an ISP, city, or egress node, but it does not reliably identify a street address.
For risk control or log analysis, combine IP with time, User-Agent, account behavior, and compliance policy instead of relying on IP alone.
