You have recently joined ABC.com as a network administrator. The previous network administrator was in the process of deploying Windows Server 2008 and was using IPv6 in the network. He was designing the network in such a way that each department in the organization would have a separate subnetted address prefix. He had assigned subnetted address prefixes to four departments and one of the departments has the subnetted address prefix as 3FFF:2FFA:3B:AC00/55.

There is no documentation which would tell you about the number of subnetted address prefixes that can be created. While looking for information, you find that the global address prefix assigned to the organization is 3FFF:2FFA:3B:A000/52.

How many more subnetted address prefixes can be assigned to the remaining departments?
