IPv6 hosts configure themselves automatically. Every interface has a self-generated link-local address and, when connected to a network, conflict resolution is performed and routers provide network prefixes via router advertisements. [19] Stateless configuration of routers can be achieved with a special router renumbering protocol. [20]
The Dynamic Host Configuration Protocol version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes, default route, local segment MTU, and other configuration data required to operate in an IPv6 network.
In IPv4, typical configuration protocols include DHCP or PPP. Although DHCPv6 exists, IPv6 hosts normally use the Neighbor Discovery Protocol to create a globally routable unicast address: the host sends router solicitation requests and an IPv6 router responds with a prefix assignment. [47]
The Neighbor Discovery Protocol (NDP), or simply Neighbor Discovery (ND), is a protocol of the Internet protocol suite used with Internet Protocol Version 6 (IPv6). [1]: §1 It operates at the internet layer of the Internet model, [2] and is responsible for gathering various information required for network communication, including the configuration of local connections and the domain name ...
In IPv6 global addresses are used end-to-end, so even home networks may need to distribute public, routable IP addresses to hosts. Since it would not be practical to manually provision networks at scale, in IPv6 networking, DHCPv6 prefix delegation ( RFC 3633 ; RFC 8415 § 6.3) is used to assign a network address prefix and automate ...
IPv6 hosts are required to support multiple addresses per interface; moreover, every IPv6 host is required to configure a link-local address even when global addresses are available. IPv6 hosts may additionally self-configure additional addresses on receipt of router advertisement messages, thus eliminating the need for a DHCP server. [2]
The Router Advertisement Daemon is used by system administrators in stateless autoconfiguration(RFC 4862. [ 3 ] ) methods of network hosts on Internet Protocol version 6 networks. When IPv6 hosts configure their network interface controllers , they multicast router solicitation (RS) requests onto the network to discover available routers.
A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [2] (routable only within the scope of private networks, but not the global IPv6 Internet).
