| /27 | 255.255.255.224 | 32 |
| /26 | 255.255.255.192 | 64 |

| /24 | 255.255.255.0 | 256 |
How many subnetworks and hosts are available per subnet?
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. 15.255) for hosts as these are required for other purposes.
What is a 27 subnet?
/27 — 8 Subnets — 30 Hosts/Subnet. Network # IP Range. Broadcast. .0.
How many hosts are available 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 hosts per 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.
What does IP address 27 mean?
/27 denote that 27 of the 32 bits of the address are the netmask hence only 5 bits are available to differentiate the computers. However, you always lose 2 addresses for broadcast and loopback, so the result is: 2^(32–27) — 2 = 2⁵ -2 = 32–2 =30. We have only 30 usable addresses on /27 allocations.
How do you calculate CIDR subnet?
Subnet Masks
Since a class B network uses 16 bits for its subnet mask, it leaves 16 bits available for host information. 216 = 65,536. 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.
How many usable hosts are on a 28 subnet?
IPv6 Subnet Calculator
| Prefix size | Network mask | Usable hosts per subnet |
|---|---|---|
| /28 | 255.255.255.240 | 14 |
| /29 | 255.255.255.248 | 6 |
| /30 | 255.255.255.252 | 2 |
| /31 | 255.255.255.254 |
What subnet mask would be used if 5 host bits are available?
The mask of 255.255. 255.224 has 5 host bits.
How many host addresses can the following network IP and subnet mask support 192.168 1.0 24?
So, a machine that has an IP address that is 192.168. 1.200 /24 would be in the same subnet. And because the subnet mask is /24, that means that the entire last octet can be used to define host machine – 28 = 256 – 2 = 254 usable addresses.
