What Is My IP Address?
Your public IP address is shown the moment this page opens: your IPv4 and your IPv6 side by side, the network each one belongs to, roughly where they place you, and whether a VPN or relay is in the way. Nothing to type, and you can copy either with one click.

What is an IP address, and what does this page show?
An IP address is the number your connection is reached at on the internet: every website you open sees it, because its answer has to come back to you. Your provider assigns it to your router or phone, and every device behind your router shares it.
Most IP checkers show one address. This one shows both your IPv4 and your IPv6 at once, the network and announced block behind each, roughly where they place you, and what the address itself says: whether a VPN covers both families, and whether your IPv6 carries your device's hardware address.

Your public IP address is at the top of this page: the one every website sees. Your device also has a local IP address inside your home network; each system shows it in its network settings or with one command.

This is your public IP only when no other device between your router and the internet translates addresses: a 100.64.x.x or private address here means carrier-grade NAT or a second router.
What is the difference between a public and a private IP address?
Your public IP address is your connection's address on the internet; private addresses (like 192.168.1.23) work only inside your home or office network. Your router translates between them with NAT, so all your devices share one public IPv4 address. Many providers add a second layer, carrier-grade NAT, and share one public address among many customers.

What is the difference between IPv4 and IPv6?
An IPv4 address is 32 bits, written as four numbers from 0 to 255; an IPv6 address is 128 bits, written as eight groups of hex digits. IPv4 has about 4.3 billion addresses and ran out (the last free blocks went to the regional registries in 2011), so homes share one through NAT. IPv6 has enough for every device to get its own.

Why does my IPv6 address change every day?
Your device makes up the second half of its IPv6 address, the interface ID. Most pick a random one and replace it regularly: a temporary address is used for new connections for one day by default (RFC 8981). Older setups build it from the network card's MAC address (EUI-64, with ff:fe in the middle), which lets sites recognise the device on any network; the address breakdown above flags it.
What can someone do with my IP address?
Not much on its own: it shows your provider and a rough area, not your name or street. Every site you visit sees and logs it. Only your provider's records link an address to a customer, and providers normally release them only when the law requires it.

A stranger with your address can see your provider and area, report it, block it or, rarely, send unwanted traffic to it: keep your router updated and don't forward ports you don't use.
Why does my IP address change, and how do I change it?
Most home connections get a dynamic address: the provider hands it out (by DHCP or PPPoE) and may change it when the router reconnects, though many keep the same one for months. IPv6 changes more often on purpose: devices start a new temporary address every day. A static IP that never changes is a fixed assignment, often a paid extra.

Why does Google show a different IP address?
Google shows one address: when your IPv6 works, that is usually your IPv6, while sites without IPv6 see your IPv4. Both are yours. Devices prefer IPv6 when both work, and browsers race the two (Happy Eyeballs), so this page asks for each family separately to show the pair.
One device, two addresses, three kinds of site
250 msBrowsers start IPv6 first and try IPv4 if IPv6 hasn't connected within about 250 ms (Happy Eyeballs, RFC 8305), so on a working dual-stack line Google sees IPv6.
