Easy IP Blocker is a lightweight security plugin that lets you block unwanted IP addresses directly from your WordPress dashboard. Protect your site from malicious traffic, brute-force login attempts, and spam by maintaining a blocklist with just a few clicks.
Your entire blocklist is stored as a single plain-text option — one entry per line. There is no database table, no import/export workflow, and no complicated UI. Just copy, paste, and save. Back up your list by copying the textarea contents to a text file, or restore it by pasting one back in. It is that simple.
Need to block IPs faster? Use the built-in WP-CLI commands to add, remove, or list entries without ever opening the dashboard.
Features:
<ul>
<li>Block individual IPs, CIDR ranges, or wildcard patterns</li>
<li>CDN/proxy-aware IP detection — supports Cloudflare, Fastly, Akamai, AWS CloudFront, Sucuri, and custom headers</li>
<li>Auto-detects your CDN/proxy and recommends the correct setting</li>
<li>Plain-text flat list — copy and paste to back up, migrate, or restore</li>
<li>WP-CLI support (<code>wp eib add/remove/list/clear</code>) for scripting and automation</li>
<li>Lightweight and fast — no external dependencies, API calls, or extra database tables</li>
<li>Compatible with PHP 7.4 through 8.4</li>
<li>Helps prevent brute-force attacks, spam, and unauthorized access</li>
<li>Comment support — use # to annotate and organize your blocklist</li>
<li>Modern, clean admin interface with tabbed layout</li>
</ul>
Supported CDN / proxy providers:
<ul>
<li>Cloudflare — reads <code>CF-Connecting-IP</code></li>
<li>Fastly — reads <code>Fastly-Client-IP</code></li>
<li>Akamai — reads <code>True-Client-IP</code></li>
<li>AWS CloudFront — reads <code>CloudFront-Viewer-Address</code></li>
<li>Sucuri — reads <code>X-Sucuri-ClientIP</code></li>
<li>Generic proxy — reads <code>X-Forwarded-For</code></li>
<li>Custom header — specify any header name your proxy sets</li>
<li>Direct — uses <code>REMOTE_ADDR</code> when no proxy is in use</li>
</ul>
The plugin auto-detects which CDN or proxy is in front of your site and recommends the correct setting. You can also choose manually from the Settings tab.
Supported blocking formats:
<ul>
<li>Exact IP — <code>192.168.1.1</code></li>
<li>CIDR range — <code>192.168.1.0/24</code> (blocks 192.168.1.0 through 192.168.1.255)</li>
<li>Wildcard — <code>10.0.0.*</code> or <code>172.16.*.*</code> (matches any value in place of *)</li>
<li>Comments — lines starting with <code>#</code> are ignored, useful for notes</li>
</ul>
WP-CLI commands:
<ul>
<li><code>wp eib add <ip>...</code> — Append one or more entries to the blocklist</li>
<li><code>wp eib remove <ip>...</code> — Remove entries from the blocklist</li>
<li><code>wp eib delete <ip>...</code> — Alias for remove</li>
<li><code>wp eib list</code> — Show all blocked IPs and rules</li>
<li><code>wp eib clear</code> — Clear the entire blocklist</li>
</ul>
All commands that accept IPs support multiple entries in a single call. For example:
<pre><code>wp eib add 192.168.1.1 10.0.0.0/24 172.16.0.*
wp eib remove 192.168.1.1 10.0.0.0/24
</code></pre>
