How Do You Calculate The Number Of Subnets And Hosts?

How do you calculate the number of subnets?

Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.

What is the formula to calculate number of hosts?

The formula for determining the number of hosts a network supports is 2n-2, where n is the number of bits used for the host. 2n-2 is sometimes expressed as (2^n) – 2. Both indicate 2 raised to the power of n. You subtract two to reserve one IP for the network ID and one for the broadcast address.

How many hosts are in a subnet?

You can figure out how many hosts you can have in your subnet by subtracting the number of network bits from the number of total bits: in other words, 32 total bits, minus the number of network bits. Let’s use 26 as an example. A subnet with 26 network bits has six bits available for the host IP addresses.

How many hosts can the subnet 255.255 0.0 support?

Decimal Equivalent Mask Values

Subnets Hosts Mask
62 262,142 255.252.0.0
126 131,070 255.254.0.0
254 65,534 255.255.0.0
510 32,766 255.255.128.0

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

So 1024 subnets are available. Each subnet will have 6 bits for hosts. 2^6 = 64. We subtract 2 for the first and last address in the subnet, so 62 host addresses are available per subnet.

How do you find the maximum number of hosts per subnet?

Maximum number of hosts is 2^10-2 = 1022. 2 is subtracted for Number of hosts is also. The address with all bits as 1 is reserved as broadcast address and address with all host id bits as 0 is used as network address of subnet.

How many hosts are in a 23 subnet?

How do you calculate the number of hosts in Class A?

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.

How many hosts are in a 8 subnet?

How many hosts are in a bit?

There are 16 host bits because, when you convert 255.255. 0.0 to binary, there are 16 binary 0s—the last 16 bits in the mask.
How Many Hosts and How Many Subnets.

Step Example Rules to Remember
Number of host bits 16 Always defined as number of binary 0s in mask
Number of subnet bits 8 32 – (network size + host size)

What is a 255.255 254.0 subnet?

255.255.254.0 = 1 bit less than 24 bits mask, so (256 x 2) – 2 hosts = 510. And to know if an ip address is good or not regarding a certain subnet..i do the following: Is 192.168. 1.64 – 255.255.
