IPv6 CCM node IPAM

Following this discussion

There is some aspect that I don't fully understand about IPv6 node IPAM. I will add more context on my infra:
My ISP can delegate some /64, that I bind to my OPNSense local link and dispatch across my subnets. I have my 'admin subnet' setup with SLAAC, so IPv6 mask is /64 (example for my PC: xxxx:xxxx:xxxx:1883:cb10:xxxx:c1fe:xxxx/64).

But in another subnet, I have make the choice to use managed mode using DHCPv6. To have a deterministic IP on my nodes based on their mac address or/and by a static configuration. But by this way IP have a /128 mask. (ex: xxxx:xxxx:xxxx:1886:669::1/128).

My first question is, I should use SLAAC to use TalosCCM node IPAM ?

@sergelogvinov I'd really appreciate it if you could help me understand what I'm missing !

Hi, as you PC uses xxxx:xxxx:xxxx:1883:cb10:xxxx:c1fe:xxxx/64 IPv6, assign the xxxx:xxxx:xxxx:1886:669::1/64 IP for your Talos node.
