Will any AWS CloudFront IP address serve my content?

I need to move domain from one Cloudfront distribution to another. Both are in the same account. This should be fairly easy, but then I need to update my DNS record (hosted outside of AWS) to point to new CloudFront distribution. I'm worried that during the DNS propagation some users may experience outage because they would be still trying to reach my site using old IP. I need to prepare process with zero outage.

I noticed that my source and target CloudFront distibutions are from same ip range list of aws services and I tried to update my /etc/hosts file to resolve the domain request with source and target IPs and both seems to work.

Therefore, can I expect after I move the domain to new CloudFront distribution and update DNS that for users that does not have the DNS change propagated yet they will be able to reach my site using old IP in all regions? Are there any edge cases / possible issues I should be aware of?

(is there any AWS documentation that would confirm this?)
