Why block IP addresses?

There are many reasons to want to block unwanted IP addresses from accessing your website. Most of these involve protecting your site and its users from malicious activity. 

Some of the most common reasons for IP blocking include:

• Preventing Spam: Spam can be a real problem for sites that allow it - it looks unprofessional when your comments section is filled with shady ads. Blocking IP addresses prevents malicious users from using different accounts.
• Getting rid of robots: There are some commenters who are not necessarily spammers, but are obviously still bots. This can be especially problematic if your site has a user forum. Blocking IPs can quickly stop this behavior. 
• Keep unauthorized users out.Only want certain authorized users to access the site, but do not want individual accounts to be required. Restricting IP addresses to those within a specific region is an easy way to block unwanted visitors.

How do I block IP addresses?

An IP address is a unique identifier assigned to each device or network connected to the Internet. It functions similarly to an e-mail address, telling the server where to send data for display to the user.

By blocking an IP address from a website, you can prevent the device or network assigned to it from sending data back and forth between itself and the website. It is also possible to block an IP address from performing certain functions on a website, such as posting comments, but still have access to the rest of the website. We'll cover all of these options later.
