Actually, I do use DNS now to hand out some server addresses, including a local network printer. Is DHCP-PD a part of DHCPv6? Would I disable SLAAC if DHCPv6 is running?
Don't forget there are 2 sides to the router and they have completely different configurations. The WAN side has to obtain the prefix from the ISP and DHCPv6-PD is often used to do that. On the LAN side, you can use DHCPv6 to hand out host addresses, but generally SLAAC is used. With SLAAC, the device address is created by combining the prefix with either a 64 bit number based on the MAC or a random number. Often both are used. The random number address provides some measure of privacy, as it can't be traced to a specific device. The MAC based address is used if you want to have a DNS AAAA record pointing to that device. On my computer, in addition to the IPv6 link local address, I have a MAC based address and 4 random number addresses. One is current and the others are previous addresses that, while deprecated, are still valid for any existing connection. All new outgoing connections use the current random address.
