# Google Ads IP exclusion list limit

Google Ads restricts users to an IP Exclusion list of up to 500 IP addresses.

When the automatic IP blocking system detects that this 500 IP limit has been reached, it will begin to replace old IPs—those that may no longer pose a threat—with new, currently harmful IP addresses.

This process ensures that your exclusion lists remain current and effective against ongoing threats.

It's important to note that an IP address used for fraudulent activity two months ago might not be used for the same activity today. If a previously removed IP clicks on your ads again, it will be immediately blocked.
