But that's mainly because DHCP is there, not because it's the best possible way to get that particular job done.So what if I want to assign different people to different resolvers by policy?For the record: I'm not saying that DHCPv6 is never useful. DHCPv6 is intended as a stateful configuration provisioning tool, i.e., to give different hosts different configurations. If that's what you need then DHCP fits the bill. However, in most small scale environments this is not what's needed so DHCP doesn't fit the bill.
There are all sized enivronments. Political battles having partly crippled DHCPv6 in ways that end up significantly limiting IPv6 uptake into large enterprise organizations ... it's hard to describe how frustrating this is without resorting to thrown fragile objects against hard walls. As an active consultant to medium and large enterprises, this is driving me nuts. This single item is in my estimation contributing at least 6, perhaps 12 months to the worldwide average delay in IPv6 uptake. I know several organizations that would have been there six months ago had DHCPv6 not had this flaw. They're currently 6-12 months from getting there. This was predicted. That the right people didn't believe it suggests that perhaps the right people are the wrong people.
Also, the examples mentioned are about enterprise networks with stable systems. Here, DHCP works well. However, with systems that connect to different networks, things don't always work so well. I may want to use the DHCP-provided NTP servers at work, but syncing with a random NTP server when I connect to a wifi hotspot is not such a great idea.
That's a problem with insufficiently configurable network location profiles on your OS (not having a "listen to DHCP NTP here, but not elsewhere" button). -- -george william herbert george.herbert () gmail com
