Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), ... The SLAAC address generation method is implementation-dependent. IETF ...
An IPv6 network uses an address block that is a contiguous group of IPv6 addresses of a size that is a power of two. The leading set of bits of the addresses are identical for all hosts in a given network, and are called the network's address or routing prefix .
Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
Operating systems that support neither DHCPv6 nor SLAAC cannot automatically configure unicast IPv6 addresses. Operating systems that support neither DHCPv6 nor ND RDNSS cannot automatically configure name servers in an IPv6-only environment.
IPv6 hosts may automatically generate IP addresses internally using stateless address autoconfiguration (SLAAC), or they may be assigned configuration data with DHCPv6, or both. IPv6 hosts that use stateless autoconfiguration may need information other than what SLAAC provides on a given network.
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 ...
Once assigned, the ISP routes this network to the customer's home router and the home router starts advertising the new address space to hosts on the network, either via SLAAC or using DHCPv6. DHCPv6 Prefix Delegation is supported by most ISPs who provide native IPv6 for consumers on fixed networks.
Similar to a unicast address, the prefix of an IPv6 multicast address specifies its scope, however, the set of possible scopes for a multicast address is different. The 4-bit scope field (bits 12 to 15) is used to indicate where the address is valid and unique.
