Can AdSense block certain IPs from clicking on my ads?

We appreciate your concern regarding invalid clicks. Because IP addresses can be allocated from various sources, and due to the fact that valid clicks may be blocked as a result, we are not able to block IP addresses provided by publishers.

If you'd like to visit the destination of an ad to view its content or to add it to your filter list, you can use the AdSense Preview Tool, which allows you to view the ads that may show on any web page and click them without worrying about invalid clicks being generated on your account.
