What is a subnet mask and how is it used quizlet?

Subnet Mask. identifies which bits in the IP address are to be used to represent the network/subnet portion of an IP address.

Why do we need a subnet mask?

9 Answers. We need a subnet mask for IPv4 addresses because the address doesn’t give any information on the network size. Class sizes are not the network sizes. … Also to be clear the purpose of the subnet mask is to determine which hosts are on the local network and which are outside of the network.

What is the importance of subnet mask?

The purpose of the subnet mask is to split the IP address into the two components. When you combine, using a logical AND, the IP address and the mask you reveal the network address.

What is subnetting and why is it important?

Subnetting identifies a network with a range of Internet Protocol addresses in the Internet. It also allows large networks to be divided into smaller networks, each with its own set of IP addresses.

How do I find my subnet?

ProcedureUse the phone GUI to navigate to Status > TCIP/IP parameters.Note the IP address and subnet mask.From a computer on the intended network, open a command/terminal prompt. Windows: In the Run or Search bar, type cmd and click Enter. Then type ipconfig and click Enter. … Note the Subnet mask.

What is a good subnet mask?

This is a simplistic explanation, good enough for handling a subnet like 192.168. 0.1 with a mask short hand value of /24 thru /32 (long hand 255.255. 255.0 thru 255). The subnet calculator can determine the range of the clients local network by its IP address and network mask.

What is subnet mask in simple words?

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).

Why is 192.168 always used?

Long story short, we are using 192.168. X.X IP addresses because this is best practice. The IETF has created three IP ranges for private networks, with Class C being the smallest and easiest to control and maintain. This is why most routers use exactly this IP range.

How long is a subnet mask?

A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. In this way, the subnet mask separates the IP address into the network and host addresses. The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address.

What is the purpose of a subnet mask quizlet?

The subnet mask identifies the network and host portion of an IP address. It is used by hosts to identify the destination IP address as either local or remote and is also used by routers to determine the path to route packets.

How many hosts can you have 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.

What is subnet mask and why it is used?

An IP address has two components, the network address and the host address. A subnet mask separates the IP address into the network and host addresses (). … It is called a subnet mask because it is used to identify network address of an IP address by perfoming a bitwise AND operation on the netmask.

What is a 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. … 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.

What is IP address and subnet mask?

An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits).

How do you create a subnet?

ProcedureClick the Network tab.In the Subnets tab, click Create.In the Create Subnet dialog box, specify subnet details, such as the name, subnet IP address or subnet mask, range of IP addresses, gateway address, and broadcast domain. … Click Create.

How does subnet mask work?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP address and see how it’s organized.
