How to calculate number of hosts in a subnet

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 do you determine the number of hosts 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.

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 each 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.

What is host number?

A host (also known as "network host") is a computer or other device that communicates with other hosts on a network. ... On a TCP/IP network, each host has a host number that, together with a network identity, forms its own unique IP address.

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

All hosts need a network address and a broadcast address. The network and broadcast addresses are indicated by either all 1s or all 0s in the host information part of an IP address. With those two addresses always reserved, the total number of assignable hosts for a class B network is 216 - 2 = 65,534.

What is the maximum number of hosts per subnet?

As per IPv4, there can be 2^n-2 Hosts per Subnet. Where n is equal to Number of Host Bits in IPv4 Address or 32-(Number of Network Bits/Network Notation). By calculating the formula 2^n-2 for a Subnet Mask of /24 we have 254 (2^8–2) host addresses available.

What is the subnet for host ID 172.16 3.65 23?

What is the subnet for host ID 172.16. 3.65/23? A /23 is 255.255. 254.0.

How many hosts can a 192 subnet have?

192 subnet mask. This mask permits up to 4 subnets with enough host addresses for 62 hosts per subnet.

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.
