Google IP Range hosts.allow

What is it?

This is a Google IP range, and we organize it into a host.allow file.

If you’re a GCP (Google Cloud Platform) service user, this is for you!

We use the commands below to collect the IP range:

nslookup -q=TXT _netblocks.google.com 8.8.8.8
nslookup -q=TXT _netblocks2.google.com 8.8.8.8
nslookup -q=TXT _netblocks3.google.com 8.8.8.8

How to use it

Download hosts.allow and replace file to /etc/hosts.allow

Edit /etc/hosts.deny and add this content

sshd:ALL:deny
