What you see for an IP address
- Type: public, private, loopback, link-local, carrier-grade NAT, documentation or another reserved range, with the RFC that defines it.
- Reverse DNS: the PTR name the network owner set, and whether it resolves back to the same address.
- Network: the autonomous system (ASN) announcing the address, its name and prefix, from Team Cymru’s free IP-to-ASN service.
- Registered in: the country of the regional registry allocation, which is not necessarily where the server or person is.
Your own address is the one our server sees for your request. We don’t store it or look it up anywhere else.
Frequently asked questions
- Why doesn't this tool show my city?
- IP addresses don't carry a location. Geolocation services guess it from commercial databases, and the guess is often wrong by tens or hundreds of kilometres, especially on mobile networks and VPNs. We show what can be known reliably: the network that owns the address and the country where that address block is registered.
- What is a private IP address?
- Private ranges (10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16 for IPv4, fc00::/7 for IPv6) are reserved for local networks and are never routed on the internet. Your laptop probably has one at home; your router translates it to a single public address. 100.64.0.0/10 is similar but used by internet providers for carrier-grade NAT.
- Why is the IP shown here different from my computer's settings?
- Your computer shows its local (private) address. Websites see the public address of your router, mobile carrier or VPN, which is what this page shows. If you use a VPN or a privacy relay, you'll see the VPN's address instead of your own.
