Quick Answer: How do you calculate subnet and host?

Hosts per subnet: 3 bits are left to identify the host therefore the total number of hosts per subnet is 2 to the power of 3 minus 2 (1 address for subnet address and another one for the broadcast address)(2^3-2) which equals to 6 hosts per subnet.

How do you calculate host?

In simple words, the Number of hosts in any network can be calculated with the formula = 2x– 2, where x is the number of host ID bits in the IP address.

What is host per subnet?

Hosts per subnet: 3 bits are left to identify the host therefore the total number of hosts per subnet is 2 to the power of 3 minus 2 (1 address for subnet address and another one for the broadcast address)(2^3-2) which equals to 6 hosts per subnet.

How do you calculate subnet mask from number of hosts?

As first octet of network address is 192 means it is a class C address. Number of Subnets = 2^n where n is the number of bits borrowed from host address to make the subnet mask. Number of hosts = 2^(32-n) – 2 where n is the no of bits in your subnet mask.

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

Assuming you are starting with a class B address, you have 10 bits for subnets. 2^10 is 1024. So 1024 subnets are available. Each subnet will have 6 bits for hosts.

How do you calculate maximum 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 is a 255.255 255.0 subnet?

A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.

How many hosts are in a 8 subnet?
