The client validates the uniqueness of the selected address via IPv6 neighbor solicitation and sends a DHCPv6 solicit request to obtain other parameters, in particular DNS servers (Step 5).
IPv6 address configuration is provided by an internal ICMPv6 router advertisement (RA) service and a DHCPv6 service linked to the internal DHCPv4 server.
This new version enhances PPPoE access concentration to include IPv6 functionality, including a DHCPv6
Dynamic Host Configuration Protocol (DHCP)  and its modified form for IPV6 addressing DHCPV6
, rely on the use of centralized servers for ensuring unique IP address assignment.
The 6rd CE either includes the 6rd delegated prefix in its router advertisement out of its LAN-side interface so each home device can auto-configure its IPv6 address or runs a DHCPv6
server to assign IPv6 addresses from a 6rd-delegated prefix to home devices.
The DGS-3420 series also features IPv6 support, including IPv6 Tunnel, ICMPv6, DHCPv6
D?Link IPv6 support includes IPv6 Tunnel, ICMPv6, IPv6 Neighbor Discovery, DHCPv6
, RIPng, and OSPFv3.
Because the host is connected via IPv4-only access network, encapsulation and decapsulation of DHCPv6
 messages should be applied as well while communicating with DHCPv6
A lot of the vendors had no idea what the program was and what was going to be required of them.'' <p>The NIST IPv6 test plan covers basic IPv6 functionality as well as related standards such as: IP Security (IPsec), Internet Key Exchange (IKEv2), Dynamic Host Configuration Protocol (DHCPv6
), Open Shortest Path First (OSPFv3), Border Gateway Protocol (BGP4+) and multicast requirements in MLDv2.

Lastly, this product supports multiple features ranging from virtual LAN (VLAN) support, virtual router function, layer2 tunneling protocol (L2TP), IPv6 point-to-point (PPP) protocol, to dynamic host configuration protocol for IPv6 prefix delegation (DHCPv6
