2 Overview

The IP blacklist is a "block list": when an IP or CIDR range in the blacklist accesses a protected website, SamWaf blocks the request outright. It is commonly used to ban malicious sources, attacking IPs, and abusive crawler ranges.

The banner at the top of the page reads: SamWaf will block access from IPs / ranges that are in the blacklist.

3 Operation Steps

3.1 Add a Blacklist IP

1. Click the Add Blocklist IP button in the top-left corner to open the dialog.
2. Select a Website (required) — the protected site this blacklist entry applies to.
3. Enter the IP (required). A single IP or a CIDR range is supported, e.g. 1.2.3.4, 10.0.0.0/8.
4. Optionally add notes in the Remarks field.
5. Click Confirm to save.

3.2 Edit / Delete

• In the Operation column of each row, click Edit to change the website, IP, or remarks of an entry.
• Click Delete to remove a single entry (a confirmation prompt appears).

3.3 Batch Delete and Clear All

• Tick the checkboxes in front of the rows, then click Batch Delete to remove all selected entries (the button is disabled when nothing is selected).
• Click Clear All to remove all blacklist entries under the current filter (a second confirmation appears).

3.4 Export Data

Click Export Data to export the blacklist as an Excel file (ipblock.xlsx) for backup or migration.

3.5 Search

The top-right area lets you filter by Website and IP; enter values and click Search.

4 Field Reference

Field	Description
Website	The protected site this entry applies to. Required when adding/editing.
IP	The IP or range to block. Supports a single IP and CIDR, e.g. 127.0.0.1, 0.0.0.0/0. Required when adding/editing.
Remarks	Optional free-text notes.
Create Time	The creation time of the record (shown in the list, generated automatically).

Warning

Use broad ranges like 0.0.0.0/0 with caution to avoid blocking legitimate visitors. If an IP whitelist is also configured, the whitelist takes precedence and allows the traffic through.
