lans.<n>.ipv6.address (a ULA /64) is assigned to the LAN, announced with an explicit prefix (networkd only announces the delegated prefix when prefix delegation is on) and advertised as RDNSS; Unbound listens and answers on it. Checked at build time: valid IPv6 CIDR, /64, fc00::/7. Covered by the onestick VM test (client SLAAC address, ping and DNS over the ULA, RA captured on the wire), assertion cases and a unit test for the /64 prefix helper.
