Which IP addresses should I allow through my firewall?

You should allow the following IP ranges and addresses:

EU Zone


UK Zone

  • ( -
  • 2a03:2800:0300::/64

US East Zone


US West Zone


For deployments to work correctly you should also ensure that the correct ports are open on your firewall. These vary by protocol:

  • Passive FTP - ports 20, 21 and all ports higher than 1023
  • Active FTP - port 21
  • SSH/SFTP - port 22

These IP ranges are used to host all of our applications, including DeployHQ.

How to allow our IP ranges access via commonly used firewalls

Ubuntu - ufw

The default firewall configuration tool for Ubuntu is ufw and if you're running a dedicated Linux server, you should have access to it.

To allow an IP range through ufw, enter the following into your terminal:

$ sudo ufw allow from

And if you wish to restrict connections from a range to a specific TCP network port:

$ sudo ufw allow from to any port 22 proto tcp

CentOS - firewalld

With CentOS, you can use firewalld which works in a very similar way. to Ubuntu's ufw. To whitelist an IP range, run the following command in your terminal:

$ sudo firewall-cmd --zone=public --add-source=
