What Is An IP Address?

An IP address is an exclusive number online devices use to identify and communicate with each other through computer networks. This process can best be compared to how we receive mail to our home address. An IP address would be most similar to a mailing address, while the network would be compared to the town you live in. Just like our home addresses, information cannot be sent or received by devices without a specific address.

IP Address Lookup

If you're here to do an IP Lookup, this is the tool for you. It's our most popular tool on the site. The tools returns IP address details like city, state, region, etc.

Internet Speed Test

An internet speed test will show you the results of the fastest upload and download burst rates during your internet speed test from your location to the location of the test server you choose. TCP/IP degrades over distance so choose the server closest to you when performing the internet speed test.

What Is My IP API

If you need data returned to you via script, we provide an API section where you'll be able to call each of our tools and get the output in txt, json, or xml.
