Do you want to block specific IP addresses from accessing your WordPress site? Blocking IP addresses is used as a solution to block spam and hacking attacks on your website. In this article, we will show you how to block IP addresses in WordPress, and we will also show you how to find out which IP addresses needs to be blocked.

How to Block IP Addresses in WordPress

What is an IP Address?

If internet was a physical world, then think of IP addresses as country, street, and house numbers. They are basically 4 sets of numbers from 0-255 separated by dots and look like this:

Each computer connected to the internet has an IP address assigned to them by their internet service provider.

All visitors to your website have an IP address which is stored in your website’s access log files. This means that all websites that you visit also stores your IP address.

You can hide this information by using a VPN service. This allows you to hide your IP address and other personal information.

Why & When You Need to Block IP Addresses?

Blocking an IP address from accessing your website is an effective way to deal with unwanted visitors, comment spam, email spam, hacking attempts, and DDOS (denial of service) attacks.

The most common sign that your website is under a DDOS attack is that your website will frequently become inaccessible or your pages will start taking forever to load.

The other attacks are more obvious such as when you start getting spam comments or a lot of spam emails from your contact form. We have a list of ways to fight spam comments, but the last solution is to block IP addresses.

Finding Out IP Addresses You Want to Block in WordPress

WordPress stores an IP addresses for users that leave a comment on your website. You can see their IP address by visiting the comments page in your WordPress admin area.

If your website is under DDOS attack, then the best way to locate the IP addresses is by checking your server’s access log.

To see those logs, you will need to login to the cPanel dashboard of your WordPress hosting account. Next, locate the ‘logs’ section and click on the ‘Raw Access Logs’ icon.

Raw access logs

This will take you to the access logs page where you need to click on your domain name to download the access logs file.

Download access log file

Your access log file will be inside a .gz archive file. Go ahead and extract the file by clicking on it. If your computer does not have a program to handle .gz archive files, then you will need to install one. Winzip or 7-zip are two popular choices among Windows users.

Inside the archive, you will see your access log file which you can open in a plain text editor like Notepad or TextEdit.

The access log file contains raw data of all requests made to your website. Each line begins with the IP address making that request.

You need to make sure that you don’t end up blocking yourself, legit users, or search engines from accessing your website. Copy a suspicious looking IP address and use online IP lookup tools to find out more about it.

You will have to carefully look at your access logs for suspicious unusually high number of requests from a particular IP address. Tip: there’s a way to automate this that we share at the bottom of this article.

Once you have located those IP addresses, you need to copy and paste them in a separate text file.

Blocking IP Addresses in WordPress

If you just want to stop users with a specific IP address from leaving a comment on your site, then you can do that inside your WordPress admin area.

Head over to Settings » Discussion page and scroll down to ‘Comment Blacklist’ text box.

Copy and paste the IP addresses that you want to block and then click on the save changes button.

WordPress will now block users with these IP addresses from leaving a comment on your website. These users will still be able to visit your website, but they will see an error message when they try to submit a comment.

Blocking an IP Address Using cPanel

This method completely blocks an IP address from accessing or viewing your website. You should use this method when you want to protect your WordPress site from hacking attempts and DDOS attacks.

First, you need to login to cPanel dashboard of your hosting account. Now scroll down to the security section and click on ‘IP Address Deny Manager’ icon.

This will take you to the IP Address Deny Manager tool. Here you can add the IP addresses you want to block. You can add a single IP address or an IP range and then click on the add button.

You can come back to the same page again if you ever need to unblock those IP addresses.

When IP Address Blocking Doesn’t Work – Automate It!

Blocking an IP address would work if you are just blocking some basic hacking attempts, specific users, or users from specific regions or countries.

However, many hacking attempts and attacks are made using a wide range of random IP addresses from all over the world. It is impossible for you to keep up with all those random IP addresses.

That’s when you need a Web Application Firewall (WAF). For the WPBeginner website, we use Sucuri. It is a website security service that protects your website against such attacks using a website application firewall.

Basically, all your website traffic goes through their servers where it is examined for suspicious activity. It automatically blocks suspicious IP addresses from reaching your website altogether. See how Sucuri helped us block 450,000 WordPress attacks in 3 months.

  1. there is no ‘Comment Blacklist’ text box.

    if word press removed this feature, then the the part where you direct/suggest the so called option should be removed.

  2. My Wifi IP address is block in my own site for my mistake but I can log in my site by using another wifi, how to unblock my IP address with WordPress?

  3. Hi there,

    I blocked an IP Address from visiting my blog, the visitor still finds a way to visit my blog with the same IP Address.

    What would you advise?

    • In these situations, we would recommend checking with your hosting provider to ensure there are no conflicts on their end.


    • You would want to look for Disallowed Comment Keys on the discussion page due to a more recent update for where to add the IPs :)


    • From left menu (rather then comments) choose Settings -> Disussions and scroll down until you see line “Disallowed Comment Keys” and the box under. IP to blocked goes in the box, one per line.

  4. Thanks ^^ This helped me find what I was looking for to block an ip address from commenting on my articles.

  5. One website is copying my whole content without leaving any comment .
    What can I do. help me please

  6. How do I block a range of IPs (subnet)? I’m getting spam from the same subnet, let.s say ABC.CDE.*.* First part is the same, the last varies. At the moment I wrote in the blacklist section that way: ABC.CDE , but I’m not sure it’s the right way. I’ve seen this as an advice somewhere ages ago. Now one of the anti-spam plugin died out and I started to look, I’ve got another info. like this: ABC.CDE.* or like this ABC.CDE.*.* So are all those ways are Ok or only one of them? And which one?

    • It would depend on what method you are using to block the IPs but normally you would want to use the second option with two *s


      • Method – the same as in the article above, going to Discussion settings and putting IP address over there. It’s just there are no way to double check which one is working because I don’t have access to different IP…

        Thanks, I’ll change everything to ABC.CDE.*.*

  7. I have recently started a blog, the information you offer on this web site has helped me tremendously. Thank you for all of your time & work.

  8. Thanks a lot for the information, ever since I came across WPBeginner, my WordPress life has been extremely easy and stress-free and I hope you guys keep up the great work.

  9. I was looking to this answer since my site was getting so much hits and spam from particular IP addresses. I am disabling that now. Thanks!
