# How to block the chat for specific IPs

Crisp allows you to block the chatbox for some IPs, to prevent them from messaging you.

**Here is how to proceed:**  
* Go to your [Crisp dashboard](https://app.crisp.chat)  
* Head over to the **Settings** from the bottom-left icon  
* Navigate to **Settings > Chatbox Settings > Chatbox Restrictions**  
* Click on the **Add a blocked IP** button

|| We accept both IPv4 and IPv6 and CIDR notation  
---

**Here are a few examples:**  
* `44.192.61.10` will hide the chatbox only for this IPv4  
* `2607:f0d0:1002:51::4` will hide the chatbox only for this IPv6  
* `44.192.61.10/24` will hide the chatbox only for all IPs from 44.192.61.1 to 44.192.61.1254
