What is my IP address?
This page shows the public IP address your request is coming from, along with basic location, network details, and autonomous system (ASN).
Note: each request uses either IPv4 or IPv6. To compare both, access this page over IPv4-only and IPv6-only connections or hostnames.
What is an IP address?
An IP address is a unique identifier your device uses to talk to other systems on the internet. Web servers use it to know where to send responses back when you load a site or API.
IPv4 vs IPv6
IPv4 uses 32-bit addresses (e.g. 203.0.113.42). IPv6 uses 128-bit addresses (e.g. 2001:db8::1) and is designed to handle vastly more devices.
What it can reveal
IPs can reveal approximate location, ISP, and ASN, but not your exact name or street address.
Autonomous systems
An ASN identifies a network operated by an ISP, cloud provider, or organization. Routes on the internet are exchanged between ASNs.
