a global routing prefix that is used to identify the network portion of the address that has been provided by an ISP, a subnet ID that is used to identify networks inside of the local enterprise site, and an interface ID that is used to identify the local host on the network
What are three parts of an IPv6 global unicast address?

Which protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host?
the average time it takes a packet to reach the destination and for the response to return to the source and the destination device is reachable through the network
