There are currently 254 devices connected to a hospital's network. An additional 30,000 to 65,000 devices will be added to the hospital's network during the next five years, but no more than 65,000 devices. What is the most appropriate IP address class for the hospital to accommodate its network growth?

A. class C
B. class A
C. class F
D. class B

The most appropriate IP address class for the hospital to accommodate its network growth would be:

B. class A

Class A addresses provide a large number of IP addresses, which would be suitable for accommodating the additional devices that will be added to the hospital's network over the next five years. This would ensure that there are enough IP addresses available to support the expected growth without running out of addresses.
