Now, if I want to assign static addresses for devices within my home network, I don’t have a problem with v4 - everything’s RFC1918, so if the public IP changes, NBD, and I can even do it with DHCP client IDs. However, if my IPv6 PD changes and my home devices all have GUAs assigned via SLAAC, then… guess what - every IPv6 device address in my network just changed. Oops.
Practically, I’ve worked around this by manually assigning LUAs to the devices that need static v6 addresses, like my SAN and the machines that do NFS mounts from it. But 1. that’s more than annoyingly clunky - hardly the improved experience that IPv6 promised - and 2. weren’t we trying to get away from LUAs in the first place?
That is something your ISP is intentionally doing - unrelated to the IPv6 specification. There is no technical reason not to give a static net to a customer, it doesn't cost more (although some ISP charge for that). I have a static IPv6 /48 net at home and I only remember those addresses. IPv4 is still there because servers need to be reachable, but I do not remember the addresses, too nasty. :-) -- kind regards Marco Send spam to abfall1764596841@stinkedores.dorfdsl.de
