Hi I was wondering what is the standard practice for assigning global static ipv6 ip addresses. For example i have a /64 doing stateless autoconf however within this subnet I have some servers and I'm wondering if I should use the unique auto generate eui ipv6 that it automatic gets assigned and use that as the static, used this in DNS for a www server, or if I should just create a static ipv6 on this /64 myself and use that as the static and put that ip into DNS.
I believe you should be able to do either/or. The EUI-64 will be unique and consistent on your device because it uses the mac address in its calculation of what address to assign it. You'll set up the prefix that the provider gave you, and you should be safe to put this address in your DNS server. Otherwise, you can also set the static manually on the interface if you want, but either way it should be consistent across reboots.
One thought would be like Mohamed stated to statically assign your servers. I think the largest advantage to this is that if you had to replace a server due to hardware failure, the new server will have a different mac address and would calculate a different address if you used SLAC. If you statically assign it, then you would avoid having to modify DNS records, etc.
