Steps to block IP address with .htaccess

We’ll learn how to block IP addresses in this article, as well as how to let certain IP addresses to your website. This precaution is used to prevent unwanted visits or to protect the website from hackers.

In your public_html folder, you must first create a.htacsess file and add the following lines in accordance with the specifications:

1) Code to deny a specific IP address –

Deny from 192.0.5.1

This code will deny one IP address from accessing your website. Make sure you use the IP address for which you wish to work.

2) Code to deny specific domain –

Deny from 192.0.0.1/366.366.366.0

Using this code you can deny a specific domain from accessing your domain. Use the code in .htaccess file, and replace IP address and netmask value to match the domain that you wish to block.

3) Code to deny multiple IP’s in a single line of code –

While using this code, leave a blank space with each IP for separation.

Deny from 111.111.111.111 444.444.444.444 666.666.666.666

Replace IPs of your choice in .htaccess file.

4) Code to allow only a single IP –

The below code will deny access of all the other websites from every IP address except the IP address mentioned in the rule :

Order Deny,Allow
Deny from all
Allow from 222.222.222.222

This code indicates that first, we have denied all visitors and then allowed only the visitor from a specified IP address.

5) Code to deny single IPv6 address –

Use the following code to block IPv6 address through .htaccess file :

Deny from 2001:cdba:0000:0000:0000:0000:3284:7536

That’s it!
