Quick Answer: How many subnets and hosts per subnet can you get from the network?

How do you calculate subnets and hosts per subnet?

This means that to create at least 18 subnets, 5 host bits must be borrowed. To calculate the number of possible hosts per subnet, use the formula 2h – 2, where h equals the number of host bits. The reason two addresses must be subtracted is because of the network address and the broadcast address.

How many subnets and hosts per subnet can you get from the network 10.0 0.0 20?

3 Answers. The maximum number of available hosts is 4094. You cannot, of course, use the first or last IP in a subnet (e.g. 10.0. 0.0 and 10.0.

How many hosts can each subnet have?

Since the host portion has now lost two bits, the host portion will have only 22 bits (out of the last three octets). This means the complete Class A network is now divided (or subnetted) into four subnets, and each subnet can have 222 hosts (4194304).

How do you calculate the number of usable hosts per subnet?

Calculating the maximum possible number of hosts in a subnet: To find the maximum number of hosts, look at the number of binary bits in the host number above. The easiest way to do this is to subtract the netmask length from 32 ( number of bits in an IPv4 address). This gives you the number of host bits in the address.

What does IP address 192.168 1.15 29 mean?

Explanation: A broadcast address is the last address of any given network. This address cannot be assigned to a host, and it is used to communicate with all hosts on that network.

Why do we need subnetting?

Subnetting ensures that traffic destined for a device within a subnet stays in that subnet, which reduces congestion. Through strategic placement of subnets, you can help reduce your network’s load and more efficiently route traffic.
