This page contains the DigiCert dedicated IP addresses for DigiCert Online Certificate Status Protocol (OCSP), Certificate Revocation List (CRL), and a few other DigiCert services.
How do these IP addresses affect my digital certificate environment?
DigiCert certificate status IPv4 addresses
DigiCert certificate status IPv6 addresses
On July 30, 2024, at 10:00 MDT (16:00 UTC), DigiCert will assign new dedicated IPv6 addresses to our Online Certificate Status Protocol (OCSP), Certificate Revocation List (CRL), and a few other DigiCert services. If your company uses allowlists and supports or plans to support IPv6 addresses, you need to update your firewalls to allow outbound connectivity to the IPv6 addresses. See DigiCert certificate status IPv6 addresses below. |
Do you have DigiCert certificates? Do you use allowlists to control inbound and outbound connectivity to your environment?
Then, check the tables below and add the necessary IP addresses (IPv4 and IPv6) to your allowlist. You must allow outbound connectivity to these addresses to verify if a certificate should be trusted.
OCSP and CRL distribution endpoints using any of the following subdomains do not use the IPv4 or IPv6 addresses in the tables below:
What are OCSPs and CRLs used for?
Your applications and browsers call one of our OCSP or CRL endpoints to learn the revocation status of a DigiCert certificate, such as a TLS or code signing certificate.
Most of the IPv4 addresses are for the DigiCert OCSPs and CRLs. However, we have included some additional PKI Platform 8 services in the table.
