Frequently asked questions about IP addresses
What is an IP address?
An IP address is a unique number assigned to every device that connects to the internet. Your public IP — the one shown above — is what websites, servers, and online services see when you make a request. It identifies your network on the global internet, not your specific device, and it's how responses know where to come back to.
What's the difference between IPv4 and IPv6?
IPv4 addresses look like 192.0.2.1 and have been the standard since the early internet. The world has run out of new IPv4 addresses, so IPv6 was introduced — longer addresses like 2001:db8::1 that allow trillions of new devices online. Most home networks now support both in parallel, and Toolzer detects whichever your connection is using.
Is my IP address private?
Your public IP is visible to every website you visit and every server you connect to. It can reveal your approximate city and your internet provider, but not your name, your home address, or your exact location. To hide it, use a VPN or proxy — both replace your real IP with one belonging to the service.
How accurate is IP geolocation?
IP-based location is approximate. Country and region are usually correct; city is correct most of the time; precise coordinates are typically the center of your ISP's coverage area, not your house. If the result looks wrong, it's almost always because your provider routes traffic through a different city than the one you live in.
Why did my IP address change?
Most home connections use dynamic IP addresses — your provider can hand you a new one when your router restarts, after a maintenance window, or after a lease period expires. Connecting from a different network (mobile data, a café, a VPN) will also change the public IP you appear from.
Can someone find me from my IP address?
Not directly. An IP address by itself isn't tied to a personal identity — only your ISP can map an IP back to a specific subscriber, and they only do so when legally required. What websites can see is the region you're in and the network you're using, which is why we recommend a VPN whenever you're on untrusted Wi-Fi.
