NAME

dhcp6c - DHCPv6 client daemon

SYNOPSIS

dhcp6c[-vfI] [-rall|<address...>] [-R<address...>] [-P<address...>] [-cpathspec]<interface>

DESCRIPTION

dhcp6cis an implementation of the DHCPv6 client.

Using DHCPv6 messages and DHCPv6 options,dhcp6cis used to request and configure IPv6 addresses and host network configurationinformation (e.g., DNS) for a network interface from the DHCPv6 server. It canalso be used as a requesting router to request and configure Prefix Delegationfor a subnet.

The assigned IPv6 addresses and prefixes are saved as/var/lib/dhcpv6/client6.leasesXXXXXX; this file is used to request the sameaddresses and prefixes from the DHCPv6 server. Eachdhcp6cclient has a client DHCP Unique Identifier (DUID); the DUID file is saved as/var/lib/dhcpv6/dhcp6c_duid.Thedhcp6cclient configuration is defined in /etc/dhcp6c.conf.

Interface names are specified according to your operating system'sconventions. On Linux, this is typically eth0, eth1, and so on.

OPTIONS

-c pathspec: Specifies the configuration file fordhcp6c
-v: Enablesdhcp6cto print debugging messages.
-f: Enablesdhcp6cto work as a foreground application. This option is helpful for debugging.
-I: Allowsdhcp6cto request network information only. Do not configure the interface.
-r all | <addresses...>: Allowsdhcp6cto release the addresses specified.This option is used only when releasing addresses explicitly.
-R <addresses...>: Allowsdhcp6cto request the specified named addresses.
-P <addresses...>: Allowsdhcp6cto request the specified prefix delegation addresses.

FILES

/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.
