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.leas-
       esXXXXXX; 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.
