The old IPs are still valid and they will continue to work for the foreseeable future.
The new ones do not have the redirect issues that the new ones do, for example, http -> https -> http://www -> https://www, which delays loading response and SEO issues.
So the new A Records 220.127.116.11 & 18.104.22.168 will validate the right redirect path to the https://www from http://.
I apologize for the confusion that my previous message has caused.
All Webflow hosted users will start to receive communications with regards to moving to the new IPs in the coming weeks.
But for now, note that if you wish, you can start making the transition now, but you do not have to at this time.
Jeff, the update to the University Page and the Dashboard are to reflect each other so that there is no confusion moving forward.
Look for emails coming in the near future with this update.
Again, I do apologize, I thought I was responding directly to @JanneWassberg,
Have a Great Day and Happy Designing,
