With dynamic dns static IPs are not as critical. Most routers support them natively. What it does is quite simple - every time the router receives a new IP, it updates your dns entry.

Not to mention that most “dynamic” IPs change only while the router is offline and your lease is up. So as long you don’t power it off, it may not change for large intervals of time.

I have had my "dynamic" IP for two years now. I even managed to keep it when I moved to a new unit in the same appt complex

My home network also seems to have no problem holding an ip despite being dynamic. I usually have to change the mac on my router before I'll get a new ip. In 15 years, I think I've only had it change unintentionally 2 or 3 times.
