What Is A Subnet Mask

You're reading What Is A Subnet Mask, posted on Wednesday, February 16th, 2011 at 7:29 am in Internet, on BrainBloggers at the Computers blog. More after the jump.

A subnet, also referred to as a subnetwork, is described as computer systems along with devices that are linked by way of a identical network. They may be chosen by an Internet protocol address redirecting prefix that is standard between the two. Ip addresses comprise of two components, one which identifies nodes along with the other recognizes networks. The subnet mask and also Class of the address are exactly what ascertain which part identifies a network address and which identifies a node address. Handling the form boundaries along with traffic between the subnets are carried out by means of routers.

Subnets are widely-used to split a part a network directly into more compact pieces. An extremely efficient subnet is used to counteract packet collisions at an excessive rate within a large Ethernet network. Subnets are generally organized in a ordered way. The network address of the organization is separated into a tree like type and also structure.

What is a Subnet Mask

A subnet mask is an extremely essential factor of subnets. It can be a lot like an Internet protocol address but contains a mask of four bytes or perhaps 32 bits which is generally composed employing a ‘dotted-decimal’ notation. Using subnets to IP addresses may allow people to identify both the node and network parts of a domain. The ‘ones’ within the address are network bits and therefore are parts of the subnet mask. The nodes tend to be represented by ‘zeros’ which are similar to the length of the subnet.

A subnet mask is not effective at swapping an entire Internet protocol address but will continue to work collectively instead of independently. When a subnet mask is placed on an Internet protocol address it isolates the address. The ensuing two parts can be referred to as a host address and extended network address. The subnet mask is employed to discover the size of the entire subnet. In addition , it pinpoints the locations of the end point on the subnet’s ar. This can only occur if the Internet protocol address is located.

Exactly why is it known as a subnet mask? The mask facet of a subnet mask is employed to refer to exactly how a subnet covers the host pieces along with uncovers the Network Id. Only when both the dimensions and starting point of the subset is known then the end or Broadcast Id will be able to be defined. A subnet is officially chosen by its Network Id along with the ending transmission address which the subnet listens to.

What is a Subnet Mask Used For

There are many uses of a subnet mask

1. It isolates the Host and Network IDs
2. It identifies the actual network
3. It cuts down on the amount of traffic inside a network
4. It determines the amount of terminals or perhaps hosts which are presently being utilised by a similar network.

An example of an Ip address could well be 156.154.81.56 and its network mask would be 255.255.255.240 consequently:

The Internet protocol address = 10011100.10011010.01010001.00111000
The Subnet mask =11111111.11111111.11111111.11110000
The Bitwise AND = ———————————————–
and the Result is 10011100.10011010.01010001.00110000

Conclusions
Subnet masks really are a vital resource needed to communicate on along with an Ip address. Without them, packets might well be dropped as they have no redirecting to tell them all where to go. he Bitwise AND = ———————————————–
plus the Result is 10011100.10011010.01010001.00110000

Conclusions
Subnet masks really are a crucial resource needed to communicate on along with an Internet protocol address.
