To block IP ranges using .htaccess, you can use the following code:
Order Deny,Allow Deny from 192.168.1.0/24 Deny from 10.0.0.0/8 Allow from all
In this code, the "Deny from" directive is used to block specific IP ranges. You can specify the IP ranges that you want to block by providing the starting IP address followed by a slash and the subnet mask (CIDR notation). The "Allow from all" directive allows access to all other IP addresses that are not specifically blocked.
After adding this code to your .htaccess file, save the changes and upload the file to your server. This will effectively block the specified IP ranges from accessing your website.

- To prevent spam or hacking attempts from specific geographic regions or known malicious IP ranges.
- To block nuisance traffic from data scrapers, bots, or other automated tools.
- To protect sensitive information or resources from unauthorized access.
- To reduce server load and improve performance by blocking excessive traffic from certain IP ranges.

How to customize error messages for blocked IP ranges in .htaccess?
To customize error messages for blocked IP ranges in .htaccess, you can use the "ErrorDocument" directive to specify a custom error message for each type of error code. Here's how you can do it:
- Create a custom error document for the specific error code you want to customize. For example, to create a custom error message for a 403 (Forbidden) error, you can create a new HTML file with your custom message. Save this file as "custom403.html".
- Add the following line to your .htaccess file to specify the custom error document for the specific error code:
1
|
ErrorDocument 403 /custom403.html
|
Make sure to replace "/custom403.html" with the path to your custom error document file.
- Repeat the above steps for any other error codes you want to customize, such as 401 (Unauthorized) or 404 (Not Found).
- Save your .htaccess file and upload it to your server.
Now, when a user from a blocked IP range tries to access your website and receives a 403 error, they will see your custom error message instead of the default server error message.
What is the purpose of blocking IP ranges with .htaccess?
Blocking IP ranges with .htaccess is used as a security measure to prevent unauthorized access or attacks from specific IP addresses or ranges of IP addresses. This can help protect a website or server from malicious users, hackers, or bots that may attempt to exploit vulnerabilities or cause harm. By blocking certain IP ranges, website owners can control access to their website and reduce the risk of security breaches.
