The unique identifier assigned to your connection
An IP (Internet Protocol) address is a unique numeric label assigned to every device connected to the internet. It identifies your device on the network and determines your approximate geographic location. There are two versions: IPv4 (e.g. 192.168.1.1) and IPv6 (e.g. 2001:db8::1), with IPv6 becoming increasingly common as addresses run out.
Practical reasons to know your public address
Knowing your public IP helps you verify VPN connections, troubleshoot network issues, check if your ISP has changed your address, and understand what information websites can see about you. myLastIP also tracks your IP history automatically so you can monitor changes over time — useful for detecting unauthorized access or ISP rotations.
Anonymous tracking with zero personal data
We use a secure anonymous cookie to remember your visits — no personal data is stored, no account is needed. Your IP history is linked only to a random cryptographic identifier. We never share or sell any data to third parties. All connections are encrypted via HTTPS.
Understanding the two versions of Internet Protocol
IPv4 uses 32-bit addresses (e.g. 93.42.117.5) and supports about 4.3 billion unique addresses — a pool that is now fully exhausted. IPv6 uses 128-bit addresses (e.g. 2001:0db8:85a3::8a2e) and provides a virtually unlimited supply. Most modern ISPs assign both versions via dual-stack configurations. myLastIP detects which version your connection is currently using.
How precise is the location derived from your IP
IP-based geolocation typically identifies your country and city with high accuracy, but street-level precision is not possible. The location shown reflects the address assigned by your Internet Service Provider (ISP), which may differ from your physical location — especially when using a VPN, proxy, or mobile network. myLastIP uses industry-leading geolocation databases, processed entirely on our servers.
Why your IP address may change over time
Most residential connections use a dynamic IP, meaning your ISP may assign a different address each time your router reconnects. A static IP remains fixed and is common for servers, businesses, and hosting services. With myLastIP's IP history tracking, you can easily see when and how often your address changes — a useful tool for network monitoring and security auditing.
