Frequently asked questionsCommon questions answered

These answers explain common ip lookup tasks, expected input formats, and edge cases so both visitors and search engines can understand what this tool does.

What information does an IP lookup return?

An IP lookup returns the approximate city, region, country, latitude/longitude, ISP name, ASN, timezone, postal code, and whether the IP belongs to a hosting provider, anycast range, or anonymous network.

How accurate is IP geolocation?

Country-level accuracy is typically above 99%. City-level accuracy is lower — usually within 25–50 km — because ISPs often route traffic through regional hubs rather than the user's exact city.

Can I look up a domain name instead of an IP?

Yes. Enter a domain like example.com and it will be resolved to its IP address first, then the geolocation lookup runs against that IP.

What is an ASN?

An Autonomous System Number (ASN) identifies a network operator — typically an ISP, hosting provider, or large enterprise — that manages a block of IP addresses and controls its own routing policy on the internet.
