As a home user on one ISP I get /56 fixed and variable IPv4 which unless your modem is really playing up you keep for a long time even during a couple of reboots. I could pay for a fixed IPv4 address if I felt enthused.

One of other ISPs I use is still trying 6rd which I might see if I can join into the testing. Forget that idea UTM doesn't do 6rd. That ISP is only allocating /64s because of a limitation in the 6rd software.
The 3rd ISP (3G wireless) is only thinking about IPv6, bit slow these days, used to be a world leader.
