What Is My IP Address?
What is my IP address?
Your public address, plus network details when available.

If you choose Use device location, your browser will ask permission to share approximate coordinates (GPS/Wi-Fi/cell). Browsers require this pop-up so websites can’t access location quietly in the background.
Privacy: we only convert coordinates into an address if you click Convert to address.
What this means▾
Your public IP is how your internet connection identifies itself to every website and cloud service you reach. It's assigned by your ISP and can change, particularly on home or mobile connections. Knowing it matters for firewall rules, remote access config and diagnosing access problems.
Not sure if your network is configured correctly? We can check allow-lists, firewall rules, VPN behaviour and remote access - quick call, no jargon.
Book a check →Privacy note: this tool queries public IP-geolocation services. Your IP and approximate location (ISP-based, not GPS) are returned to your browser only. If you choose Use device location, your browser may share approximate coordinates with this page. We will not reverse-geocode those coordinates unless you click Convert to address. Nothing is stored server-side by Black Swan.
Want to make your public IP less visible?
A VPN can help mask your public IP address from the websites and services you visit. It can be useful when you are travelling, using public Wi-Fi, or want a little more privacy for everyday browsing.
It is not a replacement for proper cyber security. It will not stop phishing, protect Microsoft 365 accounts, patch devices, monitor suspicious activity or recover lost data. For that, you still need layered protection.

Your IP is visible. What isn’t… is everything else.
An IP checker can tell you about your internet connection. It can't tell you whether an endpoint is compromised, an account is being attacked or suspicious activity is happening quietly in the background.
That's where managed cyber security comes in. We use technologies including Huntress and Heimdal to help detect, prevent and respond to threats across devices, identities and networks.

An IP address checker can tell you about your internet connection. It cannot tell you whether an endpoint is compromised, an account is under attack, or suspicious activity is happening quietly in the background.
