What Is My IP Address
See the public IP address the internet sees when you connect, along with the network that owns it, its autonomous system number and what geolocation databases claim about its location.
This is the same view every website you visit receives. Nothing here is private information you are revealing by looking it up — it is what your connection already presents to every server it talks to.
Public and private addresses
The address shown here is your public address, assigned by your ISP and visible to every site you visit. It is almost never the address your device holds internally. Home networks use private ranges such as 192.168.0.0/16 or 10.0.0.0/8 behind NAT, so many devices share one public address and the internet sees only the shared one.
That is why the address here rarely matches what your operating system reports for your Wi-Fi adapter, and why both can be correct at the same time.
Why the location is approximate, and often wrong
Geolocation is not a property of an IP address. It is an estimate sold by commercial databases that infer location from registration records, latency measurements and user-submitted corrections. There is no lookup that returns where you physically are.
Accuracy varies enormously by connection type. Fixed residential broadband is usually right to the city. Business connections often resolve to a registered office in a different city entirely. Mobile connections geolocate to the carrier's gateway, which can be hundreds of kilometres away, and satellite frequently lands in the wrong region altogether.
Two lookup sites can also report different cities for the same address, because they license different databases. Neither is authoritative — disagreement between them is a reasonable signal that the estimate is weak.
What the ISP and ASN fields tell you
These are reliable, because internet routing depends on them being accurate. Every address block is registered to an organisation, and that registration is public. The autonomous system number identifies the network operating it — useful when reporting a routing problem, because it names the network precisely rather than approximately.
The connection type is worth noting too. Residential, mobile, corporate and datacenter addresses are treated differently by websites: datacenter and shared addresses attract more CAPTCHAs, because that is where VPNs, proxies and automated traffic tend to appear. That is a statistical bet about the address, not a judgement about you. The AS lookup shows the full picture.
IPv4, IPv6 and carrier-grade NAT
If your connection supports IPv6 you may see both an IPv4 and an IPv6 address. Which one a given site uses depends on its configuration, so the address a website records for you can differ between sites.
If your router's WAN interface shows an address in 100.64.0.0/10 while this page shows a different, ordinary public address, you are behind carrier-grade NAT — your ISP is sharing one public address across many customers. That breaks port forwarding and inbound connections, and it is worth knowing because no amount of router configuration works around it. The full explanation is here.
Using this to check a VPN
Run the lookup with your VPN disconnected, then connected, and compare more than one field. The address, the ISP or organisation, and the ASN should all change. If your home ISP is still named while the tunnel is up, it is not carrying that traffic — though split tunnelling can produce the same result deliberately, which is why the combination of fields tells you more than any single one.
