I just have a cron script running on a machine that does something like this every 10 seconds
C_IP=`dig +short my.domain`
IP=`curl https://api.ipify.org`
if(C_IP != IP) {
updateRoute53(IP)
}
This is just for my main home server. Gets the job done because if it’s out of date for a few seconds nothing matters.
I think they had to drop split screen from the Series S, at least for now.
