I want to know that how can we calculate the Subnet prefix and CIDR, when the given information is only IP address and required No of hosts. For example: Suppose we have:
IP Address= 18.104.22.168 and Required No of hosts= 60
what will be the subnet prefix and CIDR?
I know how to calculate CIDR from NETMASK, but what if there is no netmask given ?? I have been trying to solve it for hours. Please give a clue or something as I am new to this subject.
