Last Modified : 09/26/2025

This page contains the DigiCert dedicated IP addresses for api.digicert.com.

DigiCert is moving to a new dedicated IP address for api.digicert.com

On October 27, 2025, at 10:00 MDT (16:00 UTC), DigiCert will assign two new IP addresses to api.digicert.com.

• 216.168.244.57 

• 216.168.240.33

If your company uses allowlists to control outbound and inbound traffic for api.digicert.com, update your allowlist on your firewalls, security groups, or proxies to include the new IP addresses below before October 27, 2025. You must do this to keep your API integrations using api.digicert.com as they were before the move to the new IP addresses.                                                                                                                                                

How do these IP addresses affect my api.digicert.com integrations?

  1. Do you use the Direct Cert Portal API or CertCentral Services API? 
  2. Do you use api.digicert.com for these API integrations or any third-party tools/services that leverage api.digicert.com? 
  3. Do you use allowlists to control inbound and outbound connectivity to your environment?

If you answered yes to all three questions, then check the DigiCert api.digicert.com IP addresses table and add the IP addresses to your allowlist. You must allow outbound and inbound connectivity to these IP addresses for your API integration.
 

Affected services:

  • Direct Cert Portal API
  • CertCentral Services API
  • Any third-party tools/services that leverage api.digicert.com
