I think the answer for this question is wrong. It should be 255.255.248.0. The formula for calculating the subnets should be 2^n-2.


48. You are designing an IP addressing scheme for a company using CIDR compliant routing protcol and routers configured with the ip subet-zero command. You have been assigned a class B network address 172.16.4.0 and you have to divide it into 15 subnets with at minimum of 3000 hosts each. What subnet should you use? e. 255.255.240.0
