dhcp6c(8) - Linux man page

Name

Synopsis

Description

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.
