What ISP would put a 'lifetime' on your ipv6 prefix? That seems insane to me... they should give you a /48 and be done with it. Even the free tunnel brokers do that.
But then I never understood dynamic ipv4 either....
If they are using DHCP-PD, then, it comes with a lifetime whether it is static or not. The reality is that unless they need to renumber you, you'll probably get a new RA with the 60/90 minute lifetimes specified each time RAs are sent and your counters will all get reset to 60/90 for the foreseeable future. The preferred and valid lifetimes aren't limitations, they're minimums. The prefix should be yours and should be functional for you for AT LEAST the valid lifetime. Owen
