At shutdown, the client sends a Release message to the server that assigned addresses to the client, to indicate that the client will no longer use one or more of the assigned addresses. When the DHCPv4 client system shuts down normally, dhcpagent writes the current configuration information to the file /etc/dhcp/ interface .dhc , or for DHCPv6 This option enables dhcp6s to allow the Server Unicast option for the DHCPv6 client. Usually DHCPv6 clients must use multicast addresses to contact DHCPv6 server and agents. With this declaration, dhcp6s accepts unicast messages from DHCPv6 clients if they include a Server Unicast option. Examples. This is a sample of the dhcp6s.conf file. Client ID. If you are on a network with DHCPv4 that filters Client IDs based on MAC addresses, you may need to change the following line: /etc/dhcpcd.conf # Use the same DUID + IAID as set in DHCPv6 for DHCPv4 Client ID as per RFC4361. duid To: /etc/dhcpcd.conf # Use the hardware address of the interface for the Client ID (DHCPv4). clientid DHCPv6 server reserved addresses; When you select the Use delegated prefix check box, the delegated prefix name appears as the first part of the IP address. The delegated prefix name begins with the external interface device name. For example, if you enable DHCPv6 client prefix delegation on interface 0, the delegated prefix name is eth0_prefix. Package dhcp6 implements a DHCPv6 server, as described in IETF RFC 3315. MIT Licensed. At this time, the API is not stable, and may change over time. The eventual goal is to implement a server, client, and testing facilities for consumers of this package. The design of this package is inspired by Go's net/http package. The Go standard library

Feb 27, 2013 · Your computer is connected to a network that supports IPv6 connections, but fails to be assigned an IPv6 address using DHCP. Your Internet Service Provider (ISP) may indicate you have a duplicate DHCPv6 DUID and point you to this article for resolution.

DHCP-client in RouterOS is capable of being a DHCPv6-client and DHCP-PD client. So it is able to get a prefix from DHCP-PD server as well as DHCPv6 stateful address from DHCPv6 server. Quick setup example. This simple example demonstrates how to enable dhcp client to receive IPv6 prefix and add it to the pool. 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.

Note: To configure the DHCPv6 in normal-commit mode, use the same command without "rapid-commit" keyword.Also ensure that you explicitly mention the IPv6 enable command in the client interface because, if it is not not enabled, the client will not send a solicit message. Verify Commands show ipv6 dhcp pool

This document updates the text from RFC 3315 (the original DHCPv6 specification) and incorporates prefix delegation , stateless DHCPv6 , an option to specify an upper bound for how long a client should wait before refreshing information (RFC 4242), a mechanism for throttling DHCPv6 clients when DHCPv6 service is not available , and relay agent Dibbler is a free DHCPv6 software package supporting many DHCPv6 options and acting both as server and client. It is available for Linux (kernel 2.4 and 2.6) and Windows (from NT to Vista) as source code or compiled binary distribution.
