IPv6 uses something called a DUID, which ensures you get the same prefix.
https://en.wikipedia.org/wiki/DHCPv6#DHCP_Unique_Identifier Do ISP provided routers support this? :-?
I can't say for certain, but they should. pfSense certainly does.
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.
The prefix is whatever is assigned to the local network. My ISP assigns me a /56 prefix, which I can then split into 256 /64s, if I wish. I'm currently using only 3. So, my main network has a "0" as part of it's prefix, my test LAN "3" and I use "ff" for my VPN. Because of the DUID I always get the same /56. Any ISP that charges for consistent prefixes (by consistent, I mean unlikely to change) is not one I would want to do business with. The IPv6 address space is so huge, there's no reason for anyone to charge for something like that. It's just plain greed. He.net won't do that to you. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
