How do you configure the DNS if the prefix is changing every time the router reboots or the ISP sees fit?
Just a theoretical cuestion, you know I don't have an actual prefix.
IPv6 uses something called a DUID, which ensures you get the same prefix.
Do ISP provided routers support this? :-? Huh, maybe I understood badly or did not ask well. I mean the ISP prefix. Each machine gets an IP which is composed of the "external" prefix and a locally generated suffix. In my local DNS server I would have to write the whole IP and corresponding names, or use another IP number that is valid only locally. But the ISP can give me a different IP v6 prefix every time I boot the router. Spain, remember? They charge extra to fix the prefix, like for fixed IPv4 addresses. I have no personal direct confirmation of this, but it is what we expect to get. -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)
