Changes to the way that DHCP works. There are now different methods if you're handing out subnets to a router, IPs to an end device or allowing devices to (automatically) self assign. And not all devices support all methods.
- azernik 7y agoEvery device that I saw as of 4 years ago (when I was working on edge IPv6 implementation) supported the NDP/SLAAC method of assigning IP addresses, which is the default for most leaf node use cases. It's optimized for a unidirectional transmission of information from routers to leaf nodes. DHCPv6 is used for routers, which need to be given not just an individual address on the local interface but also a prefix that they can hand out to their clients. It's optimized for flows that require a confirmation from the client that it has accepted/reserved the configuration that it's been given. It is technically possible to use DHCPv6 to hand out IPs to endpoints, but I have not seen any production network in the wild that does this.
