dhcp6s - DHCPv6 server
dhcp6s [-c configfile] [-Ddf] [-k ctlkeyfile] [-p ctlport] [-P pid-file]
dhcp6s replies to DHCPv6 client as DHCPv6 server. dhcp6s can give the
following information to clients.
· IPv6 prefixes for the requesting site
· Non-temporary IPv6 addresses
· A list of the DNS server addresses
· DNS Domain Search List
· A list of the NTP server addresses
· A list of the SIP server addresses
· SIP Server domain name
· A list of the NIS server addresses
· NIS domain name
· A list of the NIS+ server addresses
· NIS+ domain name
· A list of the BCMCS server addresses
· BCMCS Server domain name
Command line options are as below:
Use configfile as the configuration file.
-d Print debugging messages.
-D Even more debugging information is printed.
-f Foreground mode (useful when debugging). Although dhcp6s usually
prints warning, debugging, or error messages to syslog(8), it
prints the messages to standard error if this option is
Use ctlkeyfile to store the shared secret to authenticate the
communication with dhcp6ctl. The default file name used when
unspecified is /etc/wide-dhcpv6/dhcp6sctlkey. The default name
is intentionally same as that for dhcp6ctl so that the server and
the control command can share the file when dhcp6ctl controls the
server on the same node, which should be the typical case.
Use ctlport as the port number listening on to communicate with
Use pid-file to dump the process ID of dhcp6s.
/etc/wide-dhcpv6/dhcp6s.conf is the default configuration file.
/var/lib/dhcpv6/dhcp6s_duid is the default file to store the server’s
is the default key file to communicate with
the control command. See dhcp6ctl(8) for
the file format.
/var/run/dhcp6s.pid is the default file that contains pid of
the currently running dhcp6s.

(DHCPv6), RFC 3315, 2003.
The dhcp6s command first appeared in WIDE/KAME IPv6 protocol stack kit.
The -n dnsserv command-line option was obsoleted by introducing a
dhcp6s is incomplete and violates DHCPv6 protocol spec, in several
aspects. To name a few:
1. it does not assign temporary IPv6 addresses (nor will).
