comment IPv6 subnetting a /64 - what will break, and how to work around it?
Don't count on IPv4 mess like NAT to work properly with IPv6. NAT was a hack, not a feature...

comment IP on different subnet mask
@shodanshok the second IP address wil cause problems because other systems won't be able to reply to it as there is no route

comment IP on different subnet mask
Then you already know the answer: the configuration they told you to make is invalid and will not work (unless you add a new subnet, put a default gateway on it and set up routing. This seems to be beyond your skill level though)

comment Internet connection redundancy with 2 ISP
They don't support IPv6 at the moment though. It is on their roadmap but it might be a good idea to get commitment from them on when they deliver. You're going to need it at some point, which will probably be sooner than you expect:)

comment IPv6: No NAT / Local Addressing + ISP Offline
And with DHCPv6-PD (Prefix Delegation) your prefix is usually valid for quite a long time (the default in the RFC is 30 days) so even if your uplink breaks you should be fine for a while.

comment How do I force IPV4 with PCS? (Pacemaker/Corosync)
Really disabling IPv6 will become harder and harder. Some operating systems are even officially unsupported with IPv6 disabled. Leaving it enabled but firewalled might be a more secure implementation from an auditing point of view... Often auditors aren't that smart though :(
