dnsmasq has sufficient services to meet the needs of DHCP and RA with IP6 for single router router users. This is the most common use for consumer routers. Its reenforced as most ISP tend to only DHCP-PD /64. dnsmasq has year over year demonstrated great flexibility in its option set, and support for off-standard DHCP clients. odhcpd has enhanced capabilities focused on IP6 such as DHCP/RA relay and NDP proxy. However, it is not as flexible in its option set. odhcpd is not as forgiving with off-standard DHCP clients. Some points may represent a long term TODO list, but it is the state currently. These changes make any such combination possible. Already odhcpd can be set as the main dhcp server. Now odhcpd can be removed or disabled and dnsmasq will take over if DHCPv6 compiled in. The existing DHCPv6 and RA UCI are translated into dnsmasq.conf. The changes focus on '--dhcp-range', '--dhcp-host', and '--dhcp-options'. DHCP host ID is least 16 bits [::1000-::FFFF], but leaves low range for typical infrastructure assignments. dnsmasq accepts DHCPv6 options in the tranditional '--dhcp-option' put they must be prefixed 'option6:'. dnsmasq will also discover SLAAC DNS entries from DHCPv4 clients MAC, and confirm with a ping at least renew. Long term TODO include improving use of dnsmasq relay options for DHCPv4 and DHCPv6 in parallel. It would also be possible to preconfigure DHCP-PD in host-with-options records for fixed infrastructure.
