Easy IP Blocker

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:

• Block individual IPs, CIDR ranges, or wildcard patterns

• CDN/proxy-aware IP detection — supports Cloudflare, Fastly, Akamai, AWS CloudFront, Sucuri, and custom headers

• Auto-detects your CDN/proxy and recommends the correct setting

• Plain-text flat list — copy and paste to back up, migrate, or restore

• WP-CLI support ( wp eib add/remove/list/clear ) for scripting and automation

• Lightweight and fast — no external dependencies, API calls, or extra database tables

• Compatible with PHP 7.4 through 8.4

• Helps prevent brute-force attacks, spam, and unauthorized access

• Comment support — use # to annotate and organize your blocklist

• Modern, clean admin interface with tabbed layout

Supported CDN / proxy providers:

• Cloudflare — reads CF-Connecting-IP

• Fastly — reads Fastly-Client-IP

• Akamai — reads True-Client-IP

• AWS CloudFront — reads CloudFront-Viewer-Address

• Sucuri — reads X-Sucuri-ClientIP

• Generic proxy — reads X-Forwarded-For

• Custom header — specify any header name your proxy sets

• Direct — uses REMOTE_ADDR when no proxy is in use

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:

• Exact IP — 192.168.1.1

• CIDR range — 192.168.1.0/24 (blocks 192.168.1.0 through 192.168.1.255)

• Wildcard — 10.0.0.* or 172.16.*.* (matches any value in place of *)

• Comments — lines starting with # are ignored, useful for notes

WP-CLI commands:

• wp eib add <ip>... — Append one or more entries to the blocklist

• wp eib remove <ip>... — Remove entries from the blocklist

• wp eib delete <ip>... — Alias for remove

• wp eib list — Show all blocked IPs and rules

• wp eib clear — Clear the entire blocklist

All commands that accept IPs support multiple entries in a single call. For example:

0/24
