I stay VPN'd all day long over Comcast. The lease is renewed every 4 days
and as long as the router is online, it will renew the same IP unless there
is a renumbering on the CMTS.

That's the same for Rogers and every other cable provider that I know of in
Canada as well.

Is your VPN set up for dynamic IP?

But how is your VPN set up? Does it require a static IP?

Again, I do not have this problem due to my VPN and ISP
work together.

I am not sure what the question is -- what Barb has indicated and I have
supported is that cable operators in Canada and the U.S. effectively provide
static IPs ( if static is defined as rarely changing).

I answered you. I have a dynamic IP that is renewed every 4 days. What
is the point you are trying to make or what is your question?
