DHCPv4 uses the MAC address and an optional Client ID to identify the client for purposes of assigning an address. Each time the same client arrives on the network, it gets the same address, if possible. DHCPv6 uses basically the same scheme, but makes the Client ID mandatory and imposes structure on it. The Client ID Jun 25, 2017 · **ROOT REQUIRED** Android doesn't support DHCPv6 out of the box, because Google doesn't want to implement this feature. For some people (especially universities and corporations) this is a serious issue, because they require control over their IPv6 addresses. This app fixes this issue. It requests an IPv6 address using DHCPv6 and makes your Android future-proof. For a full explanation on how When a relay-agent is forwarding DHCPv6 client messages, it may insert additional parameters and options before relaying the message to a DHCPv6 server. A particular option of interest is the `remote-id' option. This option will help the DHCPv6 server to identify the correct parameters to reply back to the DHCPv6 client. DHCPv6 is the version of the Dynamic Host Configuration Protocol (DHCP) for Internet Protocol Version 6 (IPv6) networks. In addition to stateless address autoconfiguration in IPv6, DHCPv6 provides an alternate solution to assign addresses, name servers and other configuration information in a manner similar to DHCP for IPv4.

DHCPv6 offers advantages over "traditional" stateless IPv6 autoconfigurations: as with IPv4, you can hand out specific addresses to clients and have them keep the same address throughout their lifetime.

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.

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 IPv6 DHCPv6 Guard is one of the IPv6 FHS (First Hop Security) mechanisms and is very similar to IPv4 DHCP snooping. This feature inspects DHCPv6 messages between a DHCPv6 server and DHCPv6 client (or relay agent) and blocks DHCPv6 reply and advertisements from (rogue) DHCPv6 servers. The default firmware provides full IPv6 support with a DHCPv6 client (odhcp6c), an RA & DHCPv6 Server (odhcpd) and a IPv6 firewall (ip6tables). Also, the default installation of the web interface includes the package luci-proto-ipv6, required to configure IPv6 from the luci web interface.
