I'm currently solving this using a script and some dhcpd-scripting for DDNS. Providing that the clients use the standard mangling to get an ipv6 address from the prefix and MAC address, then this works. If they're using the privacy extensions, then I'm assuming they don't want a DNS entry anywa

After getting servers onto IPv6, I recently had a go at trying to run IPv6 on a LAN with workstations Currently, for IPv4 a) dhcpd does not run on the router, it runs on a Debian server b) the LAN uses DHCP and dynamic DNS updates between isc-dhcp and bind For IPv6, radvd is on the router: it is
