List of Fasterize IP Addresses

Modified on Wed, 15 Jan at 5:52 PM

Some of your service providers may need to know the list of IP addresses from which Fasterize is liable to send HTTP and HTTPS traffic. For example, your hosting provider may need to ensure that the firewall cannot block these IP addresses by whitelisting them. At the same time, you should continue to accept traffic from other IP addresses in case Fasterize is unavailable.

This page aims to be the authoritative source of the current list of Fasterize IP addresses.


Some changes to expect in 2025

The list is set to change as part of the migration of part of our infrastructure to a new cloud provider. Initially, more IP addresses will need to be handled. However, once the transition is complete, we intend to review the list again to reduce the number of IP addresses included. 

Your CSE will contact you shortly to confirm that the necessary steps have been taken on your side before we proceed with this transition.



List in force since 10/06/2022
