Your public IP address
Your address is read from your own connection to our server and shown only to you. It isn't stored, and no third-party location service is used.
How it works.
Your public IP address is the address the rest of the internet sees when your device connects to a website, an app or a game server. It is assigned by your internet provider to your router or mobile connection, and every device behind that router normally shares it. The address shown above is read directly from your connection to our server, so it is the same one any other site you visit right now will see.
There are two versions of the Internet Protocol in use today. IPv4 addresses look like 203.0.113.25 - four numbers from 0 to 255 - and there are only about 4.3 billion of them, which is why providers share them between customers. IPv6 addresses look like 2001:db8::1 and come from a vastly larger pool, so each device can have its own. Many connections now have both; if the IPv6 line above says "No IPv6", your provider or router hasn't enabled it for this connection.
Your public IP is different from your private IP. Inside a home or office, the router hands out private addresses such as 192.168.1.20 or 10.0.0.15 to each phone and laptop, then uses NAT (network address translation) to send all of their traffic out through the single public address. That's why two people in the same office see the same public IP here, while their laptops show different addresses in their network settings. Use our subnet calculator to work out the private ranges in your own network.
Knowing your public IP is useful in everyday IT work: adding your office to an allow-list on a firewall, cloud server or SaaS admin panel, setting up remote access or a VPN, checking that a VPN is actually routing your traffic, or giving support teams the details they need to trace a connection problem. If you want to see who owns an address and which network it belongs to, the IP Information Lookup in our analyzer shows the ISP and ASN.
Most home and many business connections get a dynamic address that can change after a router restart or a lease renewal. If you host services, run site-to-site VPNs or need a fixed entry in a partner's firewall, ask your provider for a static IP. Some mobile and fibre providers also use carrier-grade NAT (the 100.64.0.0/10 range), which means your router doesn't hold a public address at all - inbound connections such as port forwarding then won't work without the provider's help.
On guest and hotspot networks - hotels, cafes, labour accommodation, hospitals - hundreds of users usually share one or a few public addresses. That makes per-user control at the hotspot itself important: login pages, bandwidth limits and usage logs per user rather than per IP. That's exactly what WiFiNexa, our hotspot management platform, is built for.
Questions, answered.
What is my IP address?
It's the public address shown at the top of this page. It is read from your device's connection to our server, so it's the address websites and apps see when you connect from this network right now.
What's the difference between IPv4 and IPv6?
IPv4 addresses are four numbers separated by dots (for example 203.0.113.25) and the supply is limited to about 4.3 billion. IPv6 addresses are longer, written in hexadecimal with colons (for example 2001:db8::1), and the pool is large enough for every device to have its own. Many connections use both at the same time.
Why does it say "No IPv6"?
Your connection only reached our IPv6 check over IPv4, which means IPv6 isn't active on this network. Your provider may not offer it yet, or it may be turned off on your router. Everything still works over IPv4.
Is my public IP the same as the IP in my computer's settings?
Usually not. Your computer shows its private address on the local network (such as 192.168.1.20). Your router translates that to the public address shown here using NAT, and every device behind the same router shares it.
Does my IP address change?
Often, yes. Most providers assign dynamic addresses that can change when the router restarts or the lease expires. If you need an address that never changes - for remote access, hosting or firewall allow-lists - ask your provider for a static IP.
Do you store or track my IP address?
No. The address is returned only to your own browser to display it on this page. We don't save it, and we don't send it to any third-party location service.
