You need a dhcp-range statement to enable the DHCPv6 server (or the DHCPv4 server). Even if you don't want to do dynamic address allocation, you need to use dhcp-range to declare the subnet and tell dnsmasq to use it for static address allocation only, using the static keyword. 2.) Also i have wrote following string to compile custom DHCPv6 option payload according to RFC: https://github.com/Harvie/Programs/blob/master/bash/dhcp-option.sh And included the result like this: dhcp-option-force=tag:lolo,25,00:00:00:00:00:00:01:2C:00:00:01:2C:1A:62:00:00:01:2c:00:00:01:2c:34:30:20:01:06:7c:21:90:1a:01:00:00:00:00:00:00:00:00 Is it possible to specify DHCP option with custom option id and in this hexadecimal format? Yes, that's allowed. Cheers, Simon.

No. I'd really like to do this. i am using dnsmasq to successfully serve network with 2000+ clients, but now i need to support IPv6 too, but all of these client router devices (running Mikrotik RouterOS) does not understand DHCPv6 address assignment, they only understand DHCPv6 prefix delegation (and if they need single address, they just take it from delegated prefix). And i don't even need such thing as assigning single address as i have link-local adresses and SLAAC. What i really need is prefix delegation. I've tried this: dhcp-host=id:00:03:00:01:00:0c:42:8c:3b:06,[2001:67c:2142:1a01::1/64],lol,300 and the RouterOS DHCPv6 client completely ignored it... Is it possible to get prefix delegation feature in dnsmasq? The original thought was that it wouldn't be required for the sort of use-case dnsmasq is designed for. A small router would _receive_ and delegation, and then hand out addresses from the range. Given that the IETF homenet WG seems to be moving towards recursive PD within a homenet, this may have to change. I don't anticipate it happening soon enough to solve your immediate problem though. Sorry. Cheers, Simon.
