Given the following IP address from the Class B address range using the default subnet mask: 131.107.0.0. Your network plan requires no more than 32 hosts on a subnet. When you configure the IP address in Cisco IOS software, which value should you use as the subnet mask?

a)255.255.0.0

b)255.255.128.0

c)255.255.255.128

d)255.255.255.252

Please show all steps. I barrowed 3 bits which gives 2^(number of zeros which is 5)-2 and get only 30 hosts but when i use that ip its not on answers
