In about a year of treating my comcast-assigned ipv6 address as static, it changed once.

Sadly, this happened despite me specifically requesting the same address as always. That caused me some grief. But it's not common.

My xfinity ipv4 changes once every few years, if that. I treat it as static and update things if or when it changes, which fortunately isn’t too much work. I never requested anything special regarding it, and I have a normal/non-business account. I wonder why some change often and others don’t?

		I had Xfinity for 4 years and my IP changed once in that time! Now I have fiber from centurylink, and it changes anytime I need to reboot the fiber modem or my firewall. Different companies, same metro area though. That too makes me wonder about how both manage their allocations give the difference in IP assignments.

On the other end of the connection, there are physical servers and routers. Every once in a while they change how things are connected/deployed for maintenance, upgrades, etc.

		Pretty much, I have my cable modem on continuous power and it will keep the same address pretty much forever. Two times it changed is when I had a 48 hour power outage and shut everything down, and the other time was maintenance at the cable companies side where they rebooted their equipment.
