Frequent question: How many host computers can be addressed in a 28 network?

How many hosts can there be on a 28 network?

For Class B Networks

network network mask hosts
/count possible
28 255.255.255.240 16
29 255.255.255.248 8
30 255.255.255.252 4

How many addresses are in a 28 network?

Subnet Mask Cheat Sheet

Addresses Netmask
/ 30 4 255.255.255.252
/ 29 8 255.255.255.248
/ 28 16 255.255.255.240
/ 27 32 255.255.255.224

How many hosts can live on a 27 network?

A subnet mask has 32 bits. If the CIDR notation is /27 it indicates that there are 5 bits left to create subnets. Using the 2n-2 formula, or 25 – 2, or 32 – 2, you see the answer is 30. This is how many hosts you can have on the network.

How many hosts can be on the same network as your computer?

1.0. You need to create 5 sub networks each network has a maximum of 10 hosts. We can only use the first 8 bits for out subnets as these 8 bits have been allocated as host addresses. So Subnet masks of 255.255.

What does 28 mean in IP address?

The number 28 means the subnet mask off that IP address is 255.255.255.248 meaning this IP address belongs to a subnet of block size 16. If IP subnet-zero is enabled.

How many hosts does a 24 network have?

Subnet Mask Cheat Sheet

Addresses Hosts
/26 64 62
/25 128 126
/24 256 254
/23 512 510

What does 29 mean in IP address?

/29 means that 29 of the 32 bits of the address are the netmask, therefore, only 3 bits are available for differentiating between computers.

How do you calculate the number of hosts?

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 addresses are in a 27 subnet?
