Detailed explanation-1: -It uses the link-local address of the router interface that is attached to the LAN segment as its IPv6 default gateway address.
Detailed explanation-2: -A SLAAC host may use the following Duplicate Address Detection (DAD) process to ensure that the IPv6 GUA is unique. The host sends an ICMPv6 Neighbor Solicitation (NS) message with a specially constructed solicited-node multicast address containing the last 24 bits of IPv6 address of the host.
Detailed explanation-3: -The default gateway of our client device will be the router that sends Router Advertisements (RA) to it. Stateless autoconfiguration (SLAAC) assigns IP addresses automatically without the need for a DHCP server to keep track of the IP address of a host.
Detailed explanation-4: -What is SLAAC? SLAAC stands for Stateless Address Autoconfiguration and the name pretty much explains what it does. It is a mechanism that enables each host on the network to auto-configure a unique IPv6 address without any device keeping track of which address is assigned to which node.
