dhcpcd-discuss

Hi all,

due to some constraints from an external software protocol I need to group IPv6 addresses per network interface in link-local, manual-set, slaac- and dhcpv6-based addresses (I know, don't ask...).

I have done some research if this is possible after interface configuration via dhcpcd.

* link-local addresses can be filtered out by being 'scope=link'
* manual-set addresses can be filtered out by being permanent and not 'dynamic' and also because we set them manually of course

Unfortunately slaac- and dhcpv6-based addresses are indistinguishable as far as I can see because they share the same attributes by being 'scope=global' and 'dynamic'. I know of no other address flags which would make a difference.
Did I miss something obvious here?

If it's not possible after interface configuration, I thought about using my user-defined dhcpcd.enter-hook (or hacking dhcpcd directly?) to save 'incoming' slaac/dhcpv6 addresses in seperate text files and compare them later with the interface configuration.
Maybe someone has done a similar approach (I doubt it ;-)) or a better solution around dhcpcd?

Kind regards,
Andreas
