100% of the DHCP functionality). But apart from that, some of the choices made along the way make DHCPv6 a lot harder to use than DHCP for IPv4. Not only do you lack a default gateway (which is actually a
good thing for fate sharing reasons) but also a subnet prefix length and any extra on-link prefixes. So even if you do address configuration with DHCPv6 you need RAs for that other information.
I would note, it's not too late to fix these problems. We don't have wide spread IPv6 deployment yet, and I can't imagine it's all that hard to send a default gateway in DHCPv6, for example. ------------------------------------------------------------------------ -- Someone earlier threw out an offhand 'preferred gateway' DHCPv6 parameter as a possibility. This is actually a nifty idea... "Hey, you there, use potential gateways in the following order!" It has the same utility and simplicity that MX records do. Jamie
