IP Address Viewer
See the public IP address your connection uses, with the approximate city, region, country and provider from ipapi.co, or look up any IPv4 or IPv6 address. How it works
Use the IP Address Viewer
Your Public IP Address
Looking up your address...
Lookup Any IP Address
This tool contacts ipapi.co (and api64.ipify.org as a fallback) to find the IP address your connection uses. Those services can see your IP. Lookups of other addresses are sent to ipapi.co, except private, loopback, link-local, documentation, benchmarking, multicast, reserved and other special-purpose addresses that never have a public location: those are answered on this page and no request is sent. Nothing is saved on CalcChef servers.
About the IP Address Viewer
Your public IP address is the one websites see, and this page shows it in large type at the top, labeled IPv4 or IPv6, once ipapi.co answers. Below it are the approximate city, region, country, postal code, time zone, provider and ASN that ipapi.co holds for the address: the location of your provider's network, not of your device.
Addresses the lookup answers on the page
| Address | Answer |
|---|---|
| 192.168.1.1 | A private address (RFC 1918), used inside home and office networks |
| 127.0.0.1 | A loopback address (127.0.0.0/8), which always means this device |
| 169.254.10.20 | A link-local address (169.254.0.0/16) |
| 100.64.0.1 | Shared address space (100.64.0.0/10), used by carrier-grade NAT |
| 192.0.2.1 | A documentation address (RFC 5737) that is reserved for examples |
| 198.18.0.1 | A benchmarking address (198.18.0.0/15), used for equipment testing and not routed on the internet |
| 224.0.0.1 | A multicast address (224.0.0.0/4) |
| 255.255.255.255 | A reserved address (240.0.0.0/4, which includes 255.255.255.255) |
| ::1 | The loopback address (::1), which always means this device |
| fe80::1 | A link-local address (fe80::/10), only valid on the local network segment |
| fd12:3456::1 | A unique local address (fc00::/7), the IPv6 counterpart of a private address |
| 2001:db8::1 | A documentation address (2001:db8::/32) that is reserved for examples |
| ff02::1 | A multicast address (ff00::/8) |
| ::ffff:192.168.1.1 | An IPv4-mapped address for a private address (RFC 1918), used inside home and office networks |
| ::ffff:8.8.8.8 | Sent to ipapi.co as 8.8.8.8 |
| 192.0.0.9 | Sent to ipapi.co as 192.0.0.9 |
No request is sent for the answered addresses. Every address in 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16 gets the same private-address answer as 192.168.1.1. The IANA special-purpose address registries list these ranges as not globally reachable; 192.0.0.9 is listed as globally reachable, so it is looked up.
Typed addresses the lookup refuses
| You type | Message |
|---|---|
| 192.168.01.1 | Remove the leading zero in "01": zero-padded IPv4 numbers are ambiguous. |
| 256.1.1.1 | Each IPv4 number must be 0 to 255; 256 is too large. |
| 1.2.3 | An IPv4 address has four numbers separated by dots, for example 8.8.8.8. |
| [2001:db8::1] | Remove the square brackets: write the address alone, for example 2001:db8::1 instead of [2001:db8::1] (a port after the brackets is not part of an address). |
| fe80::1%eth0 | Remove the zone suffix (the % part) from the IPv6 address. |
| example.com | This is not an IP address. Use dotted numbers such as 8.8.8.8 or an IPv6 address such as 2001:4860:4860::8888. |
Frequently asked questions
- What is my IP address?
- The address in large type at the top of the tool. It is the public address your network uses on the internet, usually your router's or your mobile provider's, so devices behind the same router normally show the same one. It is not the private address your device has inside the network, such as 192.168.1.20.
- Why is my IP location wrong?
- The location comes from ipapi.co's records for the address, not from GPS or Wi-Fi. It is usually only as close as the city or region of your provider's network, and mobile networks and VPNs can put it in another city or country.
- Can this page tell if I am using a VPN?
- No. ipapi.co documents no VPN, proxy or Tor field, so the page shows none. With a VPN on, the address and provider shown are those of the VPN server.
- Why does 192.168.1.1 have no location?
- It is a private address, used inside home and office networks, so the page answers "192.168.1.1 is a private address (RFC 1918), used inside home and office networks. It has no public location or provider, so no request was sent." The same happens for loopback, link-local, documentation, multicast and other special-purpose addresses.
- What is sent to ipapi.co and ipify?
- When the page opens, one request goes to ipapi.co, which sees your IP address; only if that fails does a request go to api64.ipify.org. Pressing Lookup sends the address you typed to ipapi.co, unless it is one the page answers itself. The requests go from your browser straight to those services.
- What does "ipapi.co has refused this request" mean?
- ipapi.co answered HTTP 429: its free request limit was reached. Wait a few minutes, then press Retry or Lookup again.
Network use
When you open it, this tool automatically sends a request to ipapi.co (and api64.ipify.org as a fallback) to look up your public IP address, so those services see your IP; a public IP address you look up is also sent to ipapi.co, while private and reserved ranges are answered on the page without a request.
