dhcp6c(8)		 Linux System Manager's Manual		     dhcp6c(8)

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 Delega‐
       tion 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.
