You can split that /56 into multiple /64s with openSUSE as a router.
Also, why do you think your addresses will change? Dhcpv6-pd uses something called DUID which ties your prefix to the hardware, so it shouldn't change. If it doesn't change why are we even bothering with this whole discussion? Just configure your IPv6 prefix it statically and you're done. On IPv4, my dhcp address changed so seldom, it was virtually static. However, on rare occasion, my ISP did network changes that required address changes. If I had done used static config, I might find myself without a working address or conflicting with someone else. The same applies with dhcpv6-pd. The aprefix will likely not change, but you don't do anything to keep it from happening if necessary. To answer your own question - that is precisely why Koenraad thinks his "addresses will change".
The question is how often. If frequently, as some ISPs do with IPv4, then yes he has a problem. If seldom, as is the case with my IPv4 address, then no, it's not, as changes will be rare. Incidentally, with my ISP, the IPv4 lease time is 7 days. That means I could power off my modem or router for almost a week and still retain the address, as my ISP does not force unnecessary changes. I expect the same will apply with my IPv6 prefix. Here's some info on this: http://ipv6friday.org/blog/2011/12/dhcpv6/ As long as the ISP maps the prefix to the DUID, the prefixes should stay the same, unless it becomes necessary for the ISP to make some change. For example, this might happen when my ISP switches from /64 to another prefix. It would also change, if I change hardware. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
