Re: [Softwires] [dhcwg] Adoption call on draft-scskf-dhc-dhcpv4-over-dhcpv6

[<[e-mail]>]

Hi Ian,

Thanks for the clarification.
I understood from your answer: dhcpv6 will be used for both MAP and lw4over6 and both don't require draft-scskf-* for IP address + port provisioning.

Given currently no additional dhcpv4 only options is required for any of the solutions we are discussing in softwire, I do still think it is not justified to take on a solution for a problem which may not exist.

draft-scskf-* proposal can be revived when there is a real need to support dhcpv4-only options. No?

Cheers,
Med
