IP Address Changes
Description
As part of our scheduled maintenance on September 13, 2020 between 1 am – 3 am MDT (07:00 - 09:00 UTC), DigiCert is assigning new dedicated IP addresses to our CertCentral mail server, some of our services, and APIs.
What do I need to do?
Update allowlists (lists for firewalls that only allow specified IP addresses to perform certain tasks or connect to your system) and email filters by September 13, 2020 to ensure you don’t miss important emails and your DigiCert services and API integrations continue to run. The new IP addresses are in the tables below.
