An Internet Protocol address is a numerical identifier used to identify an interface or device on an IP network. IPv4 addresses use 32 bits, while IPv6 addresses use 128 bits.
IP addresses are used for routing traffic between devices and networks. Public IP addresses can be reachable across the internet, while private addresses are normally used inside local networks.
| Feature | IPv4 | IPv6 |
|---|---|---|
| Address size | 32-bit | 128-bit |
| Example | 192.168.1.1 | 2001:db8::1 |
| Address space | Smaller | Much larger |
A public IP address is assigned for communication across networks such as the public internet. Websites, servers and network services can use public addresses.
Private IP addresses are used inside local networks. Common IPv4 private ranges include 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16.
An Autonomous System Number identifies an autonomous system that participates in internet routing. Organizations such as internet service providers, cloud providers and large networks can operate autonomous systems.
ASN information can help developers and network administrators understand which network or organization is associated with an IP address.
Enter a valid IPv4 or IPv6 address.
The lookup service retrieves available network and geolocation information.
Inspect the IP, ISP, organization, ASN, location and timezone information.
IP geolocation is approximate. An IP address does not necessarily identify a person's exact physical location. Results depend on the underlying IP database and may change over time.
Use IP information for legitimate networking, troubleshooting and security administration. Do not use an IP lookup result as proof of a person's identity or exact location.

FAQ
An IP lookup retrieves available information associated with an IP address, such as network, ISP, ASN and approximate geographic information.
Usually no. IP geolocation is approximate and the accuracy varies by network, provider and database.
IPv4 uses 32-bit addresses and is commonly written as four decimal numbers separated by periods.
IPv6 uses 128-bit addresses and is written using hexadecimal groups separated by colons.
ISP stands for Internet Service Provider. It is the organization that provides internet connectivity for a network or customer.
An Autonomous System Number identifies an autonomous system participating in internet routing.
An IP lookup generally cannot reliably identify a specific person. It provides network information and, depending on the data source, approximate location.
No. Network ownership, geolocation databases and ISP information can change, so lookup results may become outdated or differ between providers.

Only public IP data is returned in browser-based lookups; private addresses are not routable on the public internet.
