# How to Filter Emails for an IP Range

If you need to filter or block multiple IP addresses, it can sometimes be much quicker and more efficient to block an IP range. In this article, we will show you how you can block an entire range of IPs from sending mail to your email addresses using cPanel and regular expressions.

## What is an IP range?

An IP range is exactly that. It is simply a group of IP addresses between one address and another. For example, many consumer routers will assign IP addresses between 192.168.1.101 and 192.168.1.150. The group of IP addresses between, and including these two addresses, would be an IP range.
