All Networks have the range form /0 to/32 

Answer: 

Explanation:

Sales network – /26 – This will provide up to 62 usable IP addresses (64-2 for 

subnet and broadcast IP) 

HR network - /27 – This will provide for up to 30 usable IP’s (32-2) 

IT - /28 – This will provide for up to 14 usable IP’s (16-2) 

Finance - /26 – Note that a /27 is 32 IP addresses but 2 of those are reserved for the network and 

broadcast IP’s and can’t be used for hosts. 

Marketing - /28 

If we add up how many IP blocks are used that is 64+32+16+64+16=192. 

A /24 contains 256 IP addresses, so 256-192=64. 

So the last unused box should be a /26, which equates to 64 addresses
