dhcp6c - DHCPv6 client daemon
dhcp6c [ -dDf ] [ -r all | <addresses...> ] [ -R <addresses...> ] [ -c pathspec ] [ -I ] <interface>
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 (e.g., 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.
-c pathspec Specifies the configuration file for dhcp6c
-d Enables dhcp6c to print debugging messages.
-D Enables dhcp6c to print verbose debugging messages.
-f Enables dhcp6c to work as a foreground application. This option is helpful for debugging.
-I Allows dhcp6c to request network information only. Do not configure the interface.
-r all | <addresses...> Allows dhcp6c to release the addresses specified. This option is used only when releasing addresses explicitly.
-R <addresses...> Allows dhcp6c to request the specified addresses.
/etc/dhcp6c.conf Contains DHCPv6 client configuration information.
/var/lib/dhcpv6/dhcp6c_duid Contains DHCPv6 client DUID.
/var/lib/dhcpv6/client6_leasesXXXXXX Contains DHCPv6 client assigned IPv6 addresses and prefixes.
Check /var/log/messages if there are errors.
