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