A network administrator is configuring a subnet for a medium-sized corporate office. Which IPv4 address class should they consider if they need up to 65,000 addresses for host devices with a default subnet mask?
Class D
Class C
Class A
Class B
Class B addresses are used where medium-sized networks are required. The default subnet mask for Class B is 255.255.0.0, enabling up to 65,536 addresses (2^16), which fits the requirement of needing up to 65,000 addresses. Class A is typically too large, offering up to approximately 16 million addresses which can be excessive and inefficient for the scenario. Class C, on the other hand, provides only 256 addresses, which would be insufficient for the requirement.
