I don’t have a static IP, and I just make sure to never ever let my DHCP lease expire. My ISP provides the same IP to the same MAC when renewing the lease. My longest streak on the same IP was three years.
As long as I always turn my router off by cutting the power, it won’t release the lease, so I keep my IP even through reboots. My last one didn’t release the lease at all, so it only ever got a new IP if it was off for over a day, or if I set a new MAC.
When my IP does change, I’ve configured my DNS record to only last an hour. So updating the domain to point to a new IP only takes an hour to update.







Technically, if you stop updating arch when it’s in a functional state it’ll never break.
