Every nic will autogenerate its own Link-Local Ipv6 address. From what I see on my computers, this address is created by the Link-Local prefix 'fe80::' and the MAC address (obfuscated). The question is: Is this address STATIC (meaning it will never change)? I ask because I have a local DNS running and want to make a local Network with 2 servers, that are only meant to be reached from the LAN.
Update:
I have found out that the Link-Local address in Windows actually does change at rare occcasions - for instance when updating the NIC's driver, so it's not totally static.
