I'd split your /56 into as many /64s as you need, and set up routing as required (either static or using some routing daemon). Run dnsmasq centrally, and use DHCpv6 relays to proxy DHCPv6 requests from the router on each /64 network back to the central dnsmasq instance. Simon. On 12/04/2020 18:2

Dear DNSmasqers, I have a setup in mind and wonder whether dnsmasq is the correct tool (since I have not found the necessary functionality in the documentation yet). We have a /56 IPv6 network, and plan to use pure DHCPv6 (no stateless autoconfiguration) in several /64 networks. There are sev
