Getting the NAT IPs


This article explains how to best enforce IP restrictions on requests from our Auth0 dev environment to test environments.

Auth0 environments route outbound/egress traffic through NAT gateways using static “NAT IP’s”.

​​​​​​​The “NAT IPs” are the IPs used by Auth0 to call external services, such as an SMTP server, a Log Streams target, or external APIs called from rules, hooks, or custom DB scripts.


Getting the NAT IPs depends on the selected deployment option.

For customers in the Public cloud, review our Auth0 IP Addresses for Allow Lists documentation.
