What are three parts of an IPv6 global unicast address? (Choose three.).
Answer: The elements that form the IPV6 global unicast address consist of three the global routing prefix which can find the address network part which is accepted by ISP, and the Subnet ID which can find the enterprise site network which is present in it, and the interface ID which determines localhost on the network.
IPv6 global unicast address:
An IPv6 global unicast address is exclusive and routable on the internet. They are almost the same as the public IPv4 address. The unicast address can only determine one node and it is used for one-to-one communication. The RFC 3587 clarifies the IPv6 global unicast address in which out of 128 bits in IPv6 three bits on the left-most are fixed 001, the other 45 bits are for global routing prefix after it 16 bits is for subnetting and the other 64 is for the host.
The fixed bits 001 and 45 bits (45+3 =48) are collectively assigned to the company as IPv6 prefixes. However, the leftmost three bits which are for the global unicast address, the global unicast address range is available from 2000 to 3fff.
The IPv6 global unicast address is based on three parts which are:
Global routing prefix:
It is the prefix that is allocated by the ISP provider to the client or site. Nowadays the RIRs allocate an a/48 global routing prefix to clients, it contains a lot of space for them.
Subnet ID:
On the organization’s website, the subnet ID can determine the subnets.
Interface ID:
The interface ID of the global unicast IPV6 is similar to the IPv4 address host part. The term is used due to a single host might have multiple interfaces with their own more than one IPv6 address. The address is easy to understand by the number of hextets.
