What is IPv6 DHCP relay?
IPv6 Access Services: DHCPv6 Relay Agent. A Dynamic Host Configuration Protocol for IPv6 (DHCPv6) relay agent, which may reside on the client’s link, is used to relay messages between the client and the server.

How to activate stateless DHCPv6 in Packet Tracer?
The 2000::/64 that you see above is the IPv6 address prefix while 64 is the prefix length. 3. Lastly, activate stateful DHCPv6 on interface fa0/0 of the router using ipv6 dhcp server command using the name of the DHCP pool . This interface will become the DHCPv6 server.
How does a stateful DHCPv6 server work?
Stateful DHCPv6 works just like DHCP for IPv4. The DHCPv6 server assigns IPv6 addresses to all DHCPv6 clients while keeping track of what IPv6 address has been assigned to what client. The server can also offer other network parameters such as DNS servers, a domain name, or any other option that a DHCP server provides.
Is there a DHCP server for IPv6 address assignment?
Stateless auto-configuration, also known as Stateless Address Auto-configuration ( SLAAC) – No DHCP server required for IPv6 address assignment to hosts; neither is manual configuration of addresses on the hosts required. Instead each host generates its address from the contents of router advertisement.
What makes up the device’s IPv6 address?
When combined, the address prefix (learnt from the router) and the interface ID make up the device’s IPv6 address. Simple! By default, SLAAC doesn’t provide anything to the client outside of an IPv6 address and a default gateway.
