CIP manages your hosts file. A hosts file is used by your browser to resolve IPs for the URLs you attempt to access. CIP puts the competition to shame - it's by far the fastest, most interactive, and most feature-rich product of its kind on the market today. Normally a browser will have to go through DNS to find the IP number for a web resource, and this takes time. By putting your URLs and IPs in your hosts file, you speed up your browser, make better use of your online time, and get where you're going a lot faster. CIP is alone in being able to collect secondary URLs right off your web pages. Secondary or embedded URLs amount to many times the DNS time spent on simply accessing the web pages themselves.
