Applies To

  • Static IP address
  • Allowlisting

Solution

There are several parts of Auth0:

  • If allowing Auth0 in the user’s firewall at the network level (outbound) as the identity service, that cannot be done as Auth0 uses a dynamic set of IP Addresses and are subject to change at any time. It is recommend allowing the domain hostname instead.
  • For inbound connections like the calls made to the databases and servers by Auth0 Rules 90, Hooks 33, or Custom Database Scripts 81, the list of IP addresses may be found at the footer section of the Custom Database Editor and the header for the Rules Editor.

In addition, when using AD Connector 49, it works by creating an outbound connection so no inbound IPs need to be allowlisted.
