Final answer:
In IPv6, the standard prefix length for networks is 64 bits, which is used for the network portion. The remaining 64 bits are available for the subnet and host assignment, making 64 bits the correct answer to the question on subnetting potential.
Step-by-step explanation:
The question pertains to Global Unicast Addresses in the context of Internet Protocol version 6 (IPv6). The standard prefix length for IPv6 networks is typically 64 bits. This means that the first 64 bits of the address are used for the network portion, leaving the remaining 64 bits available for the host portion, which includes subnetting within an organization's network.Because 64 bits are already dedicated to the network prefix, the number of possible bits that can be used for the subnet would also fall within this 64-bit space. Therefore, the correct answer to the question is a) 64 bits.
In IPv6, the interface ID (which is typically used for the host portion), is 64 bits, allowing for a large number of host addresses within each subnet.The question is asking about the number of possible bits that can be used for the subnet in the given Global Unicast Address.Based on the standard prefix length for the network, the answer would be 64 bits. This is because an IPv6 address typically consists of 128 bits, and the prefix length determines how many bits are used for the network part of the address. The remaining bits in the IPv6 address are used for the subnet and host parts of the address.In this case, since the prefix length is following the standard, we can conclude that 64 bits can be used for the subnet.
