In this video, Keith Barker covers stateless DHCP with IPv6. SLAAC enables a client, when first connecting to an IPv6 network, to automatically discover what network it's connected to and configure its host ID. But when that leaves some important option information un-configured, you need Stateless DHCP.
You're running an IPv6 network and you connect a new device to it. The device sees the network and sends a router solicitation to which the router responds with a router advertisement. Combining that router information with the network address space it receives, the client can calculate its own host or interface ID. That's SLAAC.
But there's a problem: there are no instructions to the client on which DNS servers to use for name resolutions - and IPv6 addresses can get very long, so good DNS management is essential. Keith explains, and then demonstrates live, how to train a network to ask for option information by configuring the M bit and the O bit that reside in the Router Advertisement.
