Note the multiple prefixes. IPv6 is not just IPv4 with bigger addresses. If you want to give your printers, etc. stable IPv6 addesses use ULAs.
Icky.
Better yet, just subscribe to an ISP that will give you a static prefix.
Well, judging by his prefixes, he does.
Indeed it is static but that doesn't change the argument that having a ULA works. The address selection algorithms choose the right source address for the correct destination address. The RA's for 2001:470:1f00:820::/64 could be withdrawn and the network would continue to work.
