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.

32 -c <configuration file>
33 Specifies the configuration file for dhcp6c
34
35
36 -d Enables dhcp6c to print debug messages.

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.
