What are Rublon MFA's IP ranges?

Modified on Wed, 18 Mar at 12:35 PM

Rublon API endpoint core.rublon.net uses the following static IP addresses:


• 15.197.196.218

• 3.33.239.9


If your firewall uses an allowlist, add both of the preceding IP addresses to your firewall’s allowlist and allow outbound communication over TCP port 443.


If your network policy allows filtering by FQDN, allow core.rublon.net.
