DHCPv6 and MAC Address inclusion

[scott_stone at trendmicro.com]

I've done some reading on this - the intent here was for laptops/etc that have wired and wireless cards, to get the same IP regardless.  Makes sense if you think of it that way but it destroys my datacenter use-case.  DHCPv6 was likely designed 15+ years ago like IPv6 was and by the time anyone got around to actually using IPv6 en masse (ie, 2011), it was long obsolete and hadn't had the updates/attention that IPv4/DHCPv4 got over the same time period.

 

Still scares me that there is no "private nonroutable" block of IPv6 space.  Someone screws up an ACL somewhere and bam, private/firewalled machines (DB hosts, etc) are now exposed to the internet.

Imagine that you would like to add these interfaces to separate classes and assign addresses based on their class assignment.  How could you do that with no way to differentiate the interfaces?

 

Someone dropped the ball designing DHCPv6.  I understand we all hate DHCPv4 or something (I don't), but not all ideas from DHCPv4 were bad.

	in our case, different "wires" but with dhcp relaying it goes to the same DHCP server, and the same server DUID is sent out on all NICs.

	Why would you attach more than one NIC to the same wire?
