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>

Easy IP Blocker

Quickly block unwanted IPs in your WP site with CDN/proxy-aware IP detection

LionScripts IP Blocker for WordPress allows you to block the malicious IP Addresses, Spammers and Hackers. You can block IP addresses by either using the manual blocking method or the Bulk IPs Blocking feature.
By blocking the Unwanted or Spammy IP Addresses, you can prevent hacking attempts and brute-force login attacks on your wordpress website.
Hackers do the brute-force login attacks very often to gain the access to your website, which may become a negative signal to the shared hosting service provider for your website, leading to the account suspension too, if not taken care of very soon. Some of the folks got their hosting accounts banned from their shared hosting provider as the hacking attempts consumes server resources very hugely and impacts the performance of other user accounts on the same shared server. If you are using some cloud based services like AWS EC2 or Google Cloud Machine for hosting, then such hacking attempts eats-up the bandwidth, resources and increases the number of hours of usage & eventually the server bills significantly. But there’s no need to worry now. That’s exactly what the LionScripts IP Blocker resolves.
The blocked IPs won’t be able to scrap the precious content too from your WordPress Site. You can choose to either display the blocked message or an empty page to the blocked users. To do so, you can just add the IP Address to the blocking list and anytime you can delete that IP from the blocking list if you know that it’s not performing malicious activities.
