IP Address Domain Validation

Description

Depending on your firewall configurations, you may need to "allowlist" specific DigiCert IP addresses for the HTTP Practical Demonstration domain approval process to go through.

What do I need to do?

Update allowlists (lists for firewalls that only allow specified IP addresses to perform specific tasks or connect to your system) to include the IP addresses below.

We recommend adding the DigiCert DCV Bot/1.1 to your allowlist. Adding the DigiCert DCV Bot/1.1 ensures you are covered if we add new IP addresses, as it automatically includes all the IP addresses used by the MPIC agents.

These are the IP addresses being used right now. However, we will continue to add more. If possible, add the user agent to your allowlist instead.
