This is a question i got and i just dont under stand how to do it.
An organization is assigned the network number 172.18.0.0/16, and it must create a set of subnets that supports up to 90 hosts on each subnet.
How do you Define subnet mask for this organization
What is the IP number for the Subnet number 421 explicitly in binary and decimal notation
What is the explicitly IP address of the host number 68 on the Subnet number 421
What is the broadcast address for the Subnet number 421
