My cable company assigns me a different prefix every time the modem reboots, about once a month, and I think that's pretty typical.
Really? I think my IPv6 address form Comcast has changed (maybe) twice in the last 18 months, and I think it was only once.
Could it be a non-persistent DUID on the CPE maybe? It tends to get more rare as home router implementors get their IPv6 right, but we still see some in the wild. (it makes an interesting attack vector also...) /JF
