Expanding Range of IP Addresses Used for DigiCert Services
As part of our scheduled maintenance on February 12, 2022, 22:00 – 24:00 MST (February 13, 2022, 05:00 - 07:00 UTC), DigiCert is expanding the range of IP addresses we use for our services. These additional IP addresses are part of our efforts to increase service uptime and reduce the need for service downtime during scheduled maintenance.
What do I need to do?
If your company uses allowlists*, update them to include the block of IP addresses listed below by February 12, 2022, to keep your DigiCert services and API integrations running as expected.
*Note: Allowlists are lists for firewalls that only allow specified IP addresses to perform certain tasks or connect to your system.
Additional IP addresses
Add this range of IP addresses to your allowlist: 18.104.22.168/20
Note: We are not replacing or removing any IP addresses. We are only expanding the range of IP Addresses we use to deliver our services.
