DigiCert removing support for IPv6 on 1/10/25. What does that mean for IPv6 adoption?

Apologies if this has been posted already. As someone who has been on the fence regarding IPv6, this change doesn't exactly instill confidence that IPv6 is the future. I've not removed IPv6 from my Windows/Active Directory environment, but I've also not taken steps to fully support IPv6. Some in my IT shop find it redundant and noisy and want IPv6 disabled until such a time that it is required (if ever). Part of me agrees with this sentiment as I'm both an IT minimalist and KISS proponent. But I'm also a "keep defaults unless compelling reason NOT to do so", so if IPv6 is enabled by default, there must be a good reason. I've posted questions on several subreddits before regarding IPv6, and the response is almost always 50/50 (keep/disable). So all that being said, what does DigiCert removing support for IPv6 mean for IPv6 adoption (and eventual replacement of IPv4). Good thing? Bad thing? 100% unrelated?

DigiCert moving to new dedicated IPv4 addresses for our DigiCert services and removing support for IPv6 addresses

On January 10, 2025, at 08:00 MST (15:00 UTC), DigiCert will move to a new CDN (content delivery network) and assign new dedicated IPv4 addresses to several services to our Online Certificate Status Protocol (OCSP), Certificate Revocation List (CRL), and a few other DigiCert services. We will also remove support for IPv6 addresses at this time.

If your company uses allowlists, update your allowlists to include the new IPv4 addresses by January 10, 2025, to keep your DigiCert services running as they did before the move to the new IPv4 addresses.
