An IP address is a number automatically assigned to your computer when you access the Internet. IP addresses allow computers and servers to recognize and communicate with one another. We collect IP address information to properly administer our system. The information enables us to gain aggregate knowledge of our visitors and how they use the site (to determine, for example, which pages are viewed most often). Aggregate information may be shared with ACS vendors. To maintain your anonymity, we do not associate IP addresses with records containing personal information.
