IP information can help you narrow a site owner's country or region (and sometimes the actual city), type of IP assignment, ISP, etc. Enter several domain names below to find the IP addresses for each in just moments.

Reverse IP lookup can help you find and block spammers, pinpoint an online scammer or find out where referrers are coming from in your site stats. To find the hostname for several sites, simply enter the IP addresses below and click "Continue" to get immediate results.
Find out the ping response time for any domain name or IP address using this helpful tool. If you need to know whether or not a site is responding when requested or how quickly it responds, the Ping Domain/IP tool makes it as easy as 1-2-3! The term "ping" refers to a program that was developed years ago to verify that computers on a network or online actually exist and are connected. It is widely used by developers and IT support technicians to test Internet connections and sites within Intranet systems and on the World Wide Web. Now you can have access to this process and "ping" your site or any other domain or IP address to find out if it is actually connected and how quickly it pulls up on the Web. Just enter your domain name or IP address below to get the ping results.
With the Reverse IP/Look-up Tool you can find out the hostname for any given IP address. The IP address, or Internet Protocol address, is a numerical address given to websites or networks.

It is particularly useful if you need to find out where referrers or spam is coming from when unusual IP addresses show up in your site's statistics. Enter the IP address in the field below to find this information.
