You said "Dynamic IP addresses typically also have a forced disconnect at a regular interval.", which is false in pretty much every DHCP scenario I have ever seen.

A change in an IP lease should result in no downtime whatsoever, because addressing is not the same as routing. A routing change would have exactly the same effect on a static IP.

I then pointed out that an overlay network means you don't have to worry about that anyway.

I think you need to reread whatever comments you think you are responding to, as there is clearly something out of sync with your replies.
