SYNOPSIS

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

DESCRIPTION

15       dhcp6c is an implementation of the DHCPv6 client.
16
17       Using DHCPv6 messages and DHCPv6 options, dhcp6c is used to request and
18       configure  IPv6  addresses  and  host network configuration information
19       (i.e. DNS) for a network interface from the DHCPv6 server. It can  also
20       be  used as a requesting router to request and configure Prefix Delega‐
21       tion for a subnet.
22
23       The   assigned   IPv6   addresses   and   prefixes   are    saved    as
24       /var/lib/dhcpv6/client6.leasesXXXXXX;  this file is used to request the
25       same addresses and prefixes from the DHCPv6 server. Each dhcp6c  client
26       has  a  client DHCP Unique Identifier (DUID); the DUID file is saved as
27       /var/lib/dhcpv6/dhcp6c_duid.   The  dhcp6c  client   configuration   is
28       defined in /etc/dhcp6c.conf.

OPTIONS

32       -c <configuration file>
33              Specifies the configuration file for dhcp6c
34
35
36       -d     Enables dhcp6c to print debug messages.
37
38
39       -D     Enables dhcp6c to print verbose debug messages.
40
41
42       -f     Enables dhcp6c to work as a foreground application.  This option
43              is helpful for debugging.
44
45
46       -I     Allows dhcp6c to request network information only.
47
48
49       -r <all | ipv6 addresses>
50              Allows dhcp6c to release the addresses.   This  option  is  used
51              only when releasing addresses explicitly.
52
53
54       -R <ipv6 addresses>
55              Allows dhcp6c to request the specified addresses.
