 # Question: What Is The Proper Subnet Mask For An IP Address Of 192.168 1.1 24?

## What is IP subnet?

A subnetwork or subnet is a logical subdivision of an IP network.

The practice of dividing a network into two or more networks is called subnetting.

Computers that belong to a subnet are addressed with an identical most-significant bit-group in their IP addresses..

## What is the subnet mask for 192.168 212 24?

172.17What is the subnet mask for 192.168. 212/24, written in CIDR notation? Is 172.17.

## What does a subnet look like?

The subnet mask looks a lot like an ip address. It is made up of four eight bit numbers separated by periods. These numbers once again range from 0 to 255.

## How do you subnet?

255.248 or /29.STEP 1: Convert to Binary.STEP 2: Calculate the Subnet Address. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask. … STEP 3: Find Host Range. … STEP 4: Calculate the Total Number of Subnets and Hosts Per Subnet.

## What is the CIDR for one IP address?

CIDR introduced a new method of representation for IP addresses, now commonly known as CIDR notation, in which an address or routing prefix is written with a suffix indicating the number of bits of the prefix, such as 192.0. 2.0/24 for IPv4, and 2001:db8::/32 for IPv6.

## Which of the following is the best definition of IP spoofing?

IP spoofing is the creation of Internet Protocol (IP) packets which have a modified source address in order to either hide the identity of the sender, to impersonate another computer system, or both.

## What does 23 mean in IP address?

## What is a subnet mask number?

A subnet mask is a number that defines a range of IP addresses available within a network. A single subnet mask limits the number of valid IPs for a specific network. Multiple subnet masks can organize a single network into smaller networks (called subnetworks or subnets).

## How many host addresses can the following IP and subnet mask support 192.168 1.0 24?

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.

## What does 24 mean at the end of an IP address?

There are two parts to an IP address, the network number and the host number. The subnet mask shows what part is which. /24 means that the first 24 bits of the IP address are part of the Network number (192.168. 0) the last part is part of the host address (1-254).

## What happens if the subnet mask is incorrect?

As an example, if you create four subnets (such as in the subnetting example) but use the incorrect subnet mask of 255.255. 255.0 in your TCP/IP configuration, hosts will not be able to determine that some computers are on different subnets than their own.

## What does a 24 subnet mask mean?

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.
