What Is My IP Address?
Your public IP address is shown at the top, with both IPv4 and IPv6 if your connection has them, plus the approximate location, internet provider and time zone that websites see. Use the other tabs to look up any IP address or to work out a subnet, netmask, CIDR block or IP range.
Free · No sign-up · IP lookups use public services (ipify, GeoJS)
How to use it
- Open the page: your public IP address appears at the top within a second or two.
- Read the IPv4 and IPv6 lines, the approximate location and your internet provider. Press Copy IP to copy it.
- To check another address, open IP lookup, paste the IP and press Look up.
- To plan a network, open the subnet calculator and type an address with a prefix, a netmask or a range.
Why use this tool
IPv4 and IPv6
Shows both addresses when your connection has them, so you can see which one websites use.
Location and ISP
Approximate city, region and country, internet provider, network number (ASN) and time zone.
VPN hint
Warns when the time zone of your IP differs from your device's, a common sign of a VPN or proxy.
IP lookup
Look up the geolocation and provider of any public IP, and get a plain explanation of private and reserved ones.
Subnet and CIDR calculator
Network, broadcast, netmask, wildcard, host range and binary view, plus a range to CIDR converter. Works offline.
No tracking
No sign-up and nothing stored on our side. Only the lookup services you choose to use see the address.
What is an IP address?
An IP address is the number that identifies a connection on the internet, like a postal address for data. Your router gets a public IP address from your internet provider, and every website you visit sees it.
Inside your home or office, each device has its own private address, usually starting with 192.168, 10 or 172.16 to 172.31. Those are only used on the local network and are hidden behind the router's public address.
IPv4 and IPv6
IPv4 addresses are four numbers from 0 to 255, such as 203.0.113.42. There are only about 4.3 billion of them, so many providers now share addresses or add IPv6.
IPv6 addresses are longer and written in hexadecimal, such as 2001:db8::1. Many connections have both. Browsers usually prefer IPv6 when a site supports it, so this page shows both.
How accurate is IP location?
IP geolocation comes from databases that map address blocks to places. The country is right most of the time, the region often, and the city only sometimes. It never shows your street or house.
Mobile networks, company networks, VPNs and satellite internet can make you appear in another city or country, because the address belongs to the provider's gateway, not to your device.
Subnet cheat sheet
The prefix after the slash is how many bits belong to the network. Each step down doubles the number of addresses. Two addresses in each subnet are kept for the network and the broadcast, except in /31 and /32.
| Prefix | Netmask | Addresses | Usable hosts |
|---|---|---|---|
| /30 | 255.255.255.252 | 4 | 2 |
| /29 | 255.255.255.248 | 8 | 6 |
| /28 | 255.255.255.240 | 16 | 14 |
| /27 | 255.255.255.224 | 32 | 30 |
| /26 | 255.255.255.192 | 64 | 62 |
| /25 | 255.255.255.128 | 128 | 126 |
| /24 | 255.255.255.0 | 256 | 254 |
| /22 | 255.255.252.0 | 1,024 | 1,022 |
| /20 | 255.255.240.0 | 4,096 | 4,094 |
| /16 | 255.255.0.0 | 65,536 | 65,534 |
Private and special address ranges
These ranges are never routed on the public internet, so they have no location:
- 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16: private home and office networks.
- 100.64.0.0/10: shared by internet providers (carrier-grade NAT).
- 127.0.0.0/8 and ::1: loopback, the device itself.
- 169.254.0.0/16 and fe80::/10: link-local, used when no router hands out addresses.
- fc00::/7: private IPv6 networks.
Frequently asked questions
How do I find my IP address?
Open this page. Your public IP address is shown at the top. To find the private address of one device, look in its network or Wi-Fi settings.
Can someone find my home from my IP address?
Not from the IP alone. It points to your provider and an approximate area. Only your provider can link the address to a customer, usually only with a court order.
Why does my IP show the wrong city?
Location databases often place you at your provider's nearest hub. A VPN, a mobile network or a company network can also make you appear somewhere else.
Does my IP address change?
Most home connections have a dynamic address that can change when the router restarts or after some days. Businesses can buy a static IP that stays the same.
How do I hide my IP address?
Use a VPN, a privacy relay or the Tor browser. Websites then see the address of the service instead of yours. Check this page again to confirm it worked.
What does /24 mean?
It is CIDR notation: the first 24 bits are the network. A /24 has a netmask of 255.255.255.0, 256 addresses and 254 usable hosts.
Is my IP address stored?
Not by us. To show your address and location, your browser asks ipify and GeoJS (or ipwho.is as a backup) directly. The subnet calculator works entirely in your browser.
