## What is a 24 subnet?

Example: 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 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 a 32 subnet?

the /32 is the CIDR (shorthand) and refers to how many 1’s are in the subnet mask. For /32 that is 255.255.255.255 or 11111111.11111111.11111111.1111111. that means you can only have one ip address, on your network before needing a gateway/router to get outside that network. with /32 it’s just you.

## What is a subnet number?

A subnet number is a specific part of a subnet address in an IP address that identifies one among several subnets as the recipient or originator of a data packet. The subnet number helps browsers to accurately use the Internet to deliver messages to specific parts of a party’s full network.

## What is 255.255 255.255 used for?

255.255. 255.255 is a special broadcast address, which means “this network”: it lets you send a broadcast packet to the network you’re connected to, without actually caring about its address; in this, is similar to 127.0. 0.1, which is a virtual address meaning “local host”.

## What happens if you have the wrong subnet mask?

Incorrect Subnet Mask: If a network uses a subnet mask other than the default mask for its address class, and a client is still configured with the default subnet mask for the address class, communication will fail to some nearby networks but not to distant ones.

## Is 255.255 255.255 IP address valid?

255.255 represents the local broadcast address, which is only propagated within the network. This broadcast data cannot cross routers by default. … For the local host, this address refers to all hosts in the network segment (same broadcast domain). Therefore, this address cannot be used for communication.

## What is IP subnet?

A subnetwork or subnet is a logical subdivision of an IP network. … This results in the logical division of an IP address into two fields: the network number or routing prefix and the rest field or host identifier. The rest field is an identifier for a specific host or network interface.

## What does 255.255 255.0 tell a router?

A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). … This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0.
