Hello there,
Our hosting service requires a static IP address or a range of IP to allow the traffic to and from auth0 on our servers.
I understood that we need a custom domain with self-managed certificates to have the static IP address but another idea was to see if the domain address (xxxx.eu.auth0.com) has a range of IP or is completely dynamic.
Sorry about the tags, I didn’t find better ones.
Regards
Hi @AnthonyDaSilva
Here you can find Auth0 IP Addresses for Allow Lists.
Hope this helps!
Hi team, checking the [Auth0 IP Addresses for Allow Lists], I can see that the IPs resolved by cdn,auth0,com (18.160.130.48) aren’t listed. Where can I find all the IPs?
Hi @brean.carbajal,
Welcome to the Auth0 Community!
While Auth0 provides a list of IP addresses for their core services, CDNs like cdn.auth0.com dynamically serve content from various edge locations globally and they are not directly publicly available.
Please do not try to whitelist specific IP addresses for cdn.auth0.com. Instead, configure your firewall to allow outbound access by DNS name on port 443. This would be the recommended way to handle CDN traffic, accordingly to our Auth0 IP Addresses for Allow Lists - Inbound calls documentation as well.
Thanks,
Remus
Okay, I understand. The problem is that we use a DMZ network that uses secure DNS, and on the firewall, we use other internal network DNS, and they’re resolving differently, causing the firewall to drop the connection. That’s why we’re trying to add the entire segment to avoid that. But if you mention that it’s too large, I have the same security issue.
