How to Block a particular IP address using .htaccess File and why it’s needed..

Using a.htaccess file to block IP addresses is a typical way to improve a website’s security and functionality. For a number of reasons, you may choose to ban particular IP addresses:

1.Stopping Illegal Access:

Your website or some sensitive sections of it may be protected from unwanted access by blocking particular IP addresses. Admin panels, login pages, and any other area that should only be accessible by authorised users should pay special attention to this.

2.Mitigating Brute Force Attacks:

Websites are often targeted by automated scripts attempting to guess passwords through brute force attacks. Blocking IP addresses after a certain number of failed login attempts can help mitigate such attacks.

3.Protecting Against Malicious Activity:

Some IP addresses might be associated with malicious activity, such as hacking attempts, spamming, or other forms of cyber threats. Blocking these IP addresses can protect your website from potential harm.

4.Reducing Server Load:

Blocking unwanted traffic, such as traffic from known malicious IP addresses or from specific regions where your website is not intended to be accessed, can help reduce server load. This can be particularly important for websites experiencing high levels of traffic or those hosted on limited resources.

5.Preventing Content Scraping:

If you want to prevent other websites or bots from scraping or hotlinking your content without permission, you can block their IP addresses using .htaccess rules.

6.Dealing with Spam:

Blocking IP addresses associated with spammers can help reduce spam comments or   form submissions on your website. This is commonly done to protect blogs, forums, and other interactive websites.

Various methods for blocking visitors based on their IP address are demonstrated.

This can be useful for a variety of reasons, such as preventing some stupid script kiddie from harassing your site, preventing some creepy stalker loser from lurking around your forums, or even silencing the never-ending supply of angry trolls.

There are so many reasons why, and so many ways to stop them.

1. Block, a specific IP address

This is the one that most visitors to this page will want to use:

Deny from 123.123.123.123

Just change the IP address to the one that you want to block, and then add the code to your site’s root .htaccess file.

2. How to use .htaccess to block a domain

Denying access via links from specific domains (e.g. www.problemdomain.com) is also possible through .htaccess. The following rule will display a 403 Forbidden error to any user accessing your site from a link hosted on the targeted domain:
SetEnvIfNoCase Referer “problemdomain.com” bad_referer
Order Allow,Deny
Allow from ALL
Deny from env=bad_referer
Change the domain in the first line of the rule to target the domain you wish to block. For a more subtle approach, this rule displays a 500 Internal Server Error for anyone linking from the target domain:
RewriteEngine on
RewriteCond %{HTTP_REFERER} example.com [NC,OR]
RewriteRule .* – [F]

3. Block multiple IP addresses

If you’ve got more than one IP address that you would like to block, you can deny them all at once:

Deny from 111.111.111.111 222.222.222.222 333.333.333.333

This will block the three specified IPs: 111.111.111.111, 222.222.222.222, and 333.333.333.333. Edit the IPs to match the ones that you want to block, and then add the line to your .htaccess file.

4. How to completely disable access to your account

1 – To prevent direct access to all files and folders on your server, create the .htaccess file in the root (top folder) of your server and add the following rule:

deny from all

2 – Then click on the Save Changes button. 

5 – How to remove access restrictions through .htaccess

If you wish to remove access restrictions from your .htaccess file, simply delete the rule from the file in cPanel File Manager’s text editor and save the file.

6 – How to block all IP addresses except specific ones

If you want to block all IP addresses except specific ones, use this rule: 

Order allow,deny

Deny from all

Allow from IP1

Allow from IP2
