NAME
       dhcp6c - DHCPv6 client daemon


SYNOPSIS
       dhcp6c [-dDf] [-r all | <ipv6 addresses>] [-R <ipv6 addresses>] [-c
            <configuration file>] [-I] interface


DESCRIPTION
       dhcp6c is an implementation of the DHCPv6 client.

       Using DHCPv6 messages and DHCPv6 options, dhcp6c is used to request and
       configure IPv6 addresses and host network configuration information
       (i.e. DNS) for a network interface from the DHCPv6 server. It can also
       be used as a requesting router to request and configure Prefix
       Delegation for a subnet.

       The assigned IPv6 addresses and prefixes are saved as
       /var/lib/dhcpv6/client6.leasesXXXXXX; this file is used to request the
       same addresses and prefixes from the DHCPv6 server. Each dhcp6c client
       has a client DHCP Unique Identifier (DUID); the DUID file is saved as
       /var/lib/dhcpv6/dhcp6c_duid.  The dhcp6c client configuration is
       defined in /etc/dhcp6c.conf.


OPTIONS
       -c <configuration file>
              Specifies the configuration file for dhcp6c


       -d     Enables dhcp6c to print debug messages.


       -D     Enables dhcp6c to print verbose debug messages.


       -f     Enables dhcp6c to work as a foreground application.  This option
              is helpful for debugging.


       -I     Allows dhcp6c to request network information only.


       -r <all | ipv6 addresses>
              Allows dhcp6c to release the addresses.  This option is used
              only when releasing addresses explicitly.


       -R <ipv6 addresses>
              Allows dhcp6c to request the specified addresses.


FILES
       dhcp6c.conf
              Contains DHCPv6 client configuration information.


       dhcp6c_duid
              Contains DHCPv6 client DUID.


       client6_leasesXXXXXX
              Contains DHCPv6 client assigned IPv6 addresses and prefixes.


ERRORS
       Check /var/log/messages if there are errors.
