On my Ubuntu 22.04 server I get two global IPv6 addresses for my network interface. I would rather avoid this, since I cannot control which one is used as the source for external connections.
They are both static addresses, so not randomly generated by privacy extensions. My suspicion is that one address is from SLAAC and the other one from DHCPv6.
I tried disabling dhcpv6 in netplan.yaml but it had no effect.
So how can I disable dhcpv6 so that I only have 1 (SLAAC) address?
