Outbound IP whitelist

Help

Hi, I have a tenant in US region and need to ensure that firewall configuration allows connectivity to Auth0. It’s quite obvious to build firewall exceptions based on DNS names:

  1. auth0.com
  2. cdn.auth0.com
  3. tenant.auth0.com (IPs are resolving as AWS us-west-2 currently)

But situation becomes more complex in case I want to build IP whitelist. What would be proper outbound IP rules for Auth0 and CDN? Can my tenant move among datacenters or I can consider AWS IP range for that us-west-2 region only? Is there a dedicated/optimized IP list for Auth0 somewhere? Thanks.

There is a list of IPs for whitelisting for all the regions on the migrations page.

If you’re using a custom database, you can also find a list of IPs to whitelist in your database connections in the dashboard, by clicking on a connection and then Custom Database:

Heads up! If you are trying to access
a service behind a firewall, make sure
to open the right ports and allow
inbound connections from these IP
addresses:
35.167.74.121,35.166.202.113,35.160.3.103
