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.
Some (probably all) networks need addressing even when they're not attached to a provider.
I don't understand why this is a problem if your ISP gives you a static address. There are, of course, other sources of addresses available as well. Nobody has yet presented me a situation where I would prefer to use ULA over GUA.
while link-local is necessary it's also probably not sufficient.
True. Owen
