A clearer picture of your connection.

SUSP.us shows the network information this service can observe and what your browser chooses to share. It is a diagnostic tool, not an identity lookup.

What is my public IP address?

Your public IP is the address visible to services you connect to. A router, shared carrier gateway, VPN or proxy may be the public endpoint. It does not necessarily identify an individual device or person. This tool reports the IPv4 or IPv6 address used for its request.

How accurate is IP location?

IP geolocation is an estimate associated with a network address. It may point to an internet provider, a nearby city or a VPN exit. It is not GPS and cannot reliably identify a street address. The dashboard graphic is decorative, not a geographic map.

What can websites see about my browser?

Requests include headers such as language preferences and a user agent. JavaScript can read additional properties such as screen size, timezone and logical CPU count. Browser protections may round or restrict these values. Missing values are shown as unavailable, rather than guessed.

Can I check my VPN?

Compare your visible IP before and after connecting. A matching exit location tells you something about this request, but cannot establish that every application and protocol uses the VPN. This tool does not perform a full DNS leak test.

What does the WebRTC check do?

The optional local test creates an ICE connection without external STUN servers. The browser may expose an address, an mDNS hostname, or nothing. An empty result is not proof that a VPN has no leaks.

At home in your terminal

Curl and wget receive a readable text overview. Query formats also work independently of the user agent. Use the current site hostname until susp.us is connected.

• curl 'https://susp.us?ip' — the observed public IP.
• curl 'https://susp.us?raw' — line-separated KEY=VALUE output.
• curl 'https://susp.us?json' — structured request and network data.

Terminal responses contain server-visible information. Browser-only measurements require JavaScript.

What gets saved?

Homepage diagnostics are not saved to the application database. Managed short links have separate visit logging described in the privacy notice. Hosting providers may process operational logs.
