Which service provides dynamic global IPv6 addressing to end devices without using a server that keeps a record of available IPv6 addresses?

The service that provides dynamic global IPv6 addressing to end devices without using a centralized server is Stateless Address Autoconfiguration (SLAAC). SLAAC allows devices to automatically generate their own IPv6 addresses by combining a network prefix, typically advertised by a router, with their own interface identifier. This process enables devices to configure themselves with global addresses without the need for a server to maintain a record of available addresses.
