IP Range Regular Expression Builder

Google Analytics uses regular expressions in filters. This tool takes a range of IP addresses and generates a single regular expression that matches all IP addresses in the range.

Unfortunately, you can't see IP addresses in Google Analytics. But if you keep a local copy of the GA tracking requests, you can process them with Angelfish Software and see extra information like:

  • IP Addresses
  • Individual Clickpaths
  • Full Visitor Details
  • Stolen Bandwidth

Step 1

Enter the first IP address in the range.

First IP Address:*


Step 2

(Optional) If there are multiple IP addresses, enter the last IP address in the range. If this field is left blank, the tool will create the regular expression for the single IP address entered in step 1.

Last IP Address:


Step 3

Copy and paste the results below into the "IP address" or "Filter Pattern" field of the "Create New Filter" page.
