This article contains the steps required to block Fastwebnet.it from accessing your WordPress site using the Wordfence plugin. Fastwebnet.it or simply “fastweb” is an Italian ISP operating under the name “Fastweb SpA,IT” from which a large number of WordPress brute-force hacking attempts originate.
Intended Audience
This article is primarily intended for clients of Glimmernet’s WordPress Hosting offering, but will be applicable to anyone who administers WordPress sites running Wordfence.
Instructions
To successfully block Fastwebnet.it from accessing your site, you will first need to install the Wordfence plugin. Information on Wordfence can be found at http://www.wordfence.com/ and the plugin can be downloaded directly from inside of your WordPress installation or by going to https://wordpress.org/plugins/wordfence/
Once Wordfence is installed, you can begin blocking IP addresses by simply logging in to your WordPress admin panel and going to Wordfence >> Advanced Blocking. On this tab you will find an input for the IP address range. You’ll need to enter all 37 of the following ranges individually. We recommend naming them “Fastwebnet.it Block X of Y” but you can give them whatever name you want.
The 37 IP address ranges that you need to block are:
- 2.224.0.0 – 2.239.255.255

Hi Dave, thank you so much for this list. I have it in place for two days now and has successfully blocked all Fastwebnet.it from accessing the site in question. Well done and thank you for sharing.
Thank you for letting us know. Do you know is this still relevant today?
It may be. We have this set of rules in place on a couple of sites, but others haven’t needed it and have been fine without it and just letting Wordfence do it’s thing. You may have to test and see.
