Final answer:
IPv6 global addresses can be assigned by a DHCPv6 server, through SLAAC, or manually by a network administrator. DHCPv6 and SLAAC provide automatic methods for IP address assignment without manual intervention.
Step-by-step explanation:
While IPv6 global addresses are typically distributed by the default gateway, there are several ways they can be obtained:
- They are assigned by the DHCPv6 server
- They are manually configured by the network administrator
- They are obtained through stateless address autoconfiguration (SLAAC)
- They are randomly generated by the device
IPv6 addresses can be acquired automatically by devices on the network in a few different ways. One method is DHCPv6, where a server assigns IP addresses to devices. Another method is SLAAC, where devices automatically generate their own addresses using a method established in the IPv6 protocol that involves the network's router advertisements. Lastly, a network administrator can also manually assign IPv6 addresses to each device.
