# Google Ads limit of blocked IP addresses per campaign

Google Ads lets you exclude up to 500 IP addresses or IP ranges per campaign, which limits click fraud protection. ClickGuard works around it by managing your blocking list so there's always room for new blocks: it cleans up older exclusions based on factors like severity, and re-blocks an IP if it clicks again.

Google Ads permits the exclusion of up to **500 IP** addresses or IP ranges per campaign. While this limitation is one of the constraints of the platform, it significantly impacts click fraud protection.

## How does ClickGuard work around the 500 IP limit?

ClickGuard intelligently optimizes the management of your blocking list to ensure:

-   There is always capacity for new blocks.
-   Existing blocks remain effective as needed.  
    

To maintain an effective blocking list, ClickGuard performs regular and ad-hoc cleanups based on various factors, including but not limited to:

-   The severity of the reason for blocking the IP/range.
-   The duration of the block (expiration date or permanency).
-   The specific campaign involved.  
    

By keeping your blocking list current, ClickGuard ensures robust protection against evolving threats.

## What if an unblocked IP continues to generate clicks?

This can occur, but ClickGuard will promptly re-block the IP if it detects additional clicks. The re-blocking will be applied with increased severity to enhance the cleanup process.  

## Can cleanup be prevented for a specific IP address or range?

Yes, you can designate any block as permanent through the block/exclusion forensics feature, ensuring that it is not subject to automatic cleanup.
