How to Block Unwanted IP Addresses from Accessing Your Website Forms

Dealing with persistent spammers on your website forms can be a frustrating challenge. Fortunately, the IP Blacklist feature in the CAPTCHA - reCAPTCHA module provides an effective solution, allowing you to block specific IP addresses or entire ranges from accessing and submitting your forms.

What is an IP Blacklist, and why do you need it?

The IP Blacklist is a security feature designed to block spammers, malicious users, or bots based on their IP addresses. By blacklisting unwanted IPs, you can:

Prevent repetitive spam submissions from known offenders.
Protect your website’s forms from abuse and malicious activity.
Improve user experience by keeping your forms clean and secure.

How it works

An IP address is a unique identifier assigned to a device connected to the internet. The blacklist feature allows you to block:

Specific IP addresses (e.g., 69.89.31.226).
IP ranges using patterns (e.g., 69.89.31.* to block 69.89.31.0 to 69.89.31.255).

Step-by-step guide to adding IP Addresses to the blacklist

Follow these simple steps to set up the IP Blacklist feature in the CAPTCHA - reCAPTCHA module:

Step 1: Access the module configuration

Navigate to Modules > Module Manager.

Locate the CAPTCHA - reCAPTCHA module and click Configure.

Step 2: Add IP addresses or patterns

In the module’s configuration page, look for the IP Blacklist feature.

Click to access the input field for adding IP addresses.

Enter the IP addresses or patterns you want to block, one per line.

Example of a specific IP address: 69.89.31.226
Example of an IP range (using a pattern): 69.89.31.*

Use the * character to define ranges, replacing one or more octets. For instance:

69.*.*.* blocks all IPs starting with 69.
69.89.*.* blocks all IPs between 69.89.0.0 and 69.89.255.255.

Step 3: Save your settings

Once you’ve added the desired IPs or patterns, click the Save button to apply changes. The blacklisted IPs will no longer be able to access or submit your website forms.

Tips for effective use of IP Blacklist

Monitor activity: Use website analytics or server logs to identify spammers’ IP addresses.
Avoid blocking legitimate users: Be cautious when blocking entire ranges to prevent unintentionally restricting access to genuine customers.
Regularly update the blacklist: Add new IPs or patterns as spammers evolve their tactics.
