How important is DDI for VPN?

Probably a dumb question but how integrated does your VPN solution need to be in rendering DDI (DNS / DHCP / IPAM) services?

VPN (or at least "old school" fixed perimeter VPN) is mostly accomplished using IP whitelist tables. So that would plug into the IPAM part of DDI, right?

Does next-gen dynamic firewall stuff (like SDN / SDP) also need to plug in to DDI services? I would think it does since the SDP gateway controller would need access to IP routing tables (plus a certificate) in order to figure out which entities / users to grant access to?
