He didn't say it didn't work.  He said the logging was deficient, which is
quite true.

I complained about that via a bug report to dhcp-bugs at isc.org with title
"logging deficiencies for IPv6 on Oct 31, 2011, getting bug# 26377".  I
received no response from ISC & I've seen no improvement by the server.

It does basically work for IPv6, but the lack of logging & other shortcomings
make it much less usable than for IPv4.  I encourage submitting bug reports
about the deficient logging & anything else you find lacking about the IPv6
behavior of ISC DHCP, especially relative to IPv4.  More voices might help.
