If you came to figure out how to block multiple IP addresses in Google Analytics with 1 filter then you’re in luck.
We’ll need to use something called a regular expression (Regex) but I’ll walk you through the whole thing step-by-step.
Go to the admin section, click on filters, add filter, and name your filter.
Select “Custom Filter”
Then select “IP Address” from the drop-down
Now have your list ready of IP addresses. As an example let’s say we want to block off the following 3 IP addresses:
Put them all on 1 line in the “Filter Pattern” text box with a
| between each one. That’s the pipe key. It’s typically next to the forward-slash key:
Using our example we would have this so far:
Now add a backslash
\ before each period
. and you’ll end up with something like this:
That’s it! You can do that for as many IP addresses as you need.
