My main issue with hncp (3 years back) is it wanted to assign an IPv6 address to *everything* and I only have /60s to spare, and I didn't want to assign public ipv6 addr= esses to internal routers at all. > One thing I discovered is that I would like DHCPv6-PD lifetime capping, s= o > I can control the source address selection of hosts.

I'm rather impressed with how far odhcp has evolved since I last looked and had some code in it to manage times better but probably not what you want. https://github.com/openwrt/odhcpd In particular I was *really impressed* by the clean interface to netlink. Netlink is a PITA to deal with. It could use some more ebpf support. > -- > Mikael Abrahamsson email: swmike@swm.pp.se --=20 Dave T=C3=A4ht CEO, TekLibre, LLC http://www.teklibre.com Tel: 1-669-226-2619
