In what seems to be a previous life, I had such a script running on my win95 machine to update my IPv4 DNS with EuroDNS. I dropped it when I pensioned that win95 machine because my IPv4 address only changed when the MAC address of the CPE changed. i.e. never unless I changed hardware.
For IPv6 I need a bit more than just changing one address. What I need is to change the prefix of ALL addresses of devices reachable from outside.
