How static are the IPs for proxy-ssl.webflow.com?

I have a DNS provider that doesn’t support CNAME flattening. That shouldn’t be that big of a problem so long as the IPs of the underlying record don’t change often or without notice.

So, how often does webflow switch the IPs for proxy-ssl?

They have not changed since I have been using Webflow (2+ years). It would be a support nightmare if they did.

Interestingly, I found this:

Perhaps they still support the old IPs as well?

I use Cloudflare for DNS. It would take seconds (plus propagation) to make a change.
