Open Settings > Blacklist > IP Address. 2. Select the rule type. 3. Enter the IP value. 4. Click Add. 5. Check the Blacklist IP List to confirm the entry was created. ### Blacklist IP List | Column | Description | | --------- | ------------------------------ | | Date Time | Time when the rule was created | | Type | Rule type | | IP | Blocked IP value | | Action | Edit or remove the rule | ### Remove All Use Remove All only when you want to clear all blacklist IP entries for the account. This can immediately change how your services handle traffic, so review the list before clearing it. ### Best Practices * Prefer specific IP rules when possible. * Use wildcard or range rules carefully because they can block large networks. * Add trusted traffic to Whitelist IP Address instead of removing important blacklist entries. * Test traffic after adding a new rule. ### Related Pages | Page | Purpose | | ---------------------------------------------------------------------------------------------- | ------------------------------------------ | | [Whitelist IP Address](https://docs.stopbot.net/v2/panel-guides/settings/whitelist/ip-address) | Allow trusted IP addresses | | [Blocker](https://docs.stopbot.net/v2/panel-guides/services/blocker) | Review how Blocker handles visitor traffic | | [Blocker V2](https://docs.stopbot.net/v2/panel-guides/services/blocker-v2) | Review advanced traffic filtering |
