What are the three parts of an IPv6 global unicast address? (Choose three.)
- subnet ID
- global routing prefix
- interface ID
- subnet mask
- broadcast address
|Explanation & Hint:
The three parts of an IPv6 global unicast address are:
- Global routing prefix: This is the prefix or network portion of the address that is assigned by the provider, such as an ISP, to a customer or other organization.
- Subnet ID: This is used by an organization to identify subnets within its site. The subnet ID is part of the local administration, allowing for internal organization and routing.
- Interface ID: This is the unique identifier for an interface within a subnet. An interface ID is typically 64 bits long, often automatically generated from the MAC address of the interface using the EUI-64 format.
IPv6 does not use a subnet mask as IPv4 does; instead, the prefix length specifies the division of the address into the network and interface portions. Also, IPv6 does not have a broadcast address; it uses multicast addressing to achieve similar functionality.
