IPinsight uses a software application to determine Internet users' connection speeds and neighborhood-level geographic locations. It sells this non-personally-identifiable data to web sites, which use the data to geographically target their ads and to decide whether to use rich media ads (for fast connection speeds) or standard ads. Finally, your address information is used to make educated guesses about the demographics of your household (things like income range, education, age, gender, whether there are children present, etc.)

IPinsight Software generates Line Speed, Geography, Gender/Age estimates, User ID, and IP address information, which it transmits to the IPinsight servers for use in the preparation of the company's data file products.

Line Speed Test: On a periodic basis, the IPinsight Software communicates with the IPinsight server, which instructs the Software to request a small fixed-size web page. Once the web page is loaded the Software records the length of time between the request and the completed load. This is recorded in milliseconds. A report is sent back to the IPinsight server with the exact size (including HTTP headers) of the web page and the download time. This enables IPinsight to estimate Internet users' connections speeds (e.g. dial-up, DSL, cable).

Geography Test: IPinsight estimates neighborhood-level geography of the user based upon postal code. The IPinsight Software monitors the users' form submissions for the presence of street name and postal code name value pairs. On a periodic basis these street names and postal code values are communicated to the IPinsight server, along with the street number rounded to the nearest 50 (e.g. 115 Main Street gets transmitted as 100 Main Street). The reason for the acquisition of street names and non-specific but approximated street numbers is to determine the zip+4 location (nine-digit zip code) of the user. Once the zip+4 location has been determined, the street name is discarded.

Gender/Age estimates: IPinsight attempts to group users according to broad age ranges and gender based on form submissions. In no cases are specific birthdays or even years of birth submitted back to our servers. Genders are estimated by comparing first name form submissions to a file of common first names; in no cases are actual first names sent to our servers.

Unique Identifier: IPinsight maintains file integrity through the use of a unique random number (GUID) for each user, which is stored in the user's Windows Registry.

IP Address: Finally, when you install IPinsight's Software, it collects several bits of information about the configuration of your computer. This information includes information about the computer's hardware configuration, such as the amount of free space on your hard drive, and information about the computer's software configuration, such as the name and version of the operating system. This information is used to determine whether the IPinsight Software is compatible with your computer.
