Web analytics products like Urchin, Google Analytics, and Angelfish Software allow you to use IP addresses in filters to include/exclude traffic.
This tool creates a single regular expression that matches all IP addresses in a range.
Enter the first IP address in the range. (e.g. 18.104.22.168)
Step 3: Results
Copy and paste the results below into the "IP address" or "Filter Pattern" field of the "Create New Filter" page.
It's a good idea to test all regex in a dev/test environment before applying them to your production reports.
