Subnet mask is the network mask that is used to show the bits of IP address
. It allows you to understand which part represents the network and the host. With its help, you can identify the subnet as per the Internet Protocol address.
The mask is represented in dotted decimal notation, which is similar to IP. The most common binary code which uses the dual representation is 11111111 11111111 11111111 0000. Another popular presentation is 255.255.255.0. You can also use it to determine the information of your address.
It is preferred to set the rightmost bits to 0 as this makes the application work better. However, if you prefer the easier version, set them on the left hand side for it is the extended network part. The former contains the host section.
There are various uses of this feature. It is an essential aspect of subnetting. Your pc may not be able to assess the network and host portions without it. Another advantage is that it helps in recognition of the protocol add. You can decrease the traffic and identify the number of terminals to be connected. It enables easy segregation from the network client to the host client.
Due to its functions, the subnet mask is essential in order to establish network connection. Because of its salient features, you can know if the device is properly connected to the local subnet or remote network and thereby connect your system to the internet. Depending upon the network identified, the equipment will find the default route or hardware address. If at all your computer cannot assess the information, the device can substitute it from MAC (Media Access Control) address that is obtained from layer two of Open System Interconnection Model (OSIM). You need to compute the subnet address correctly for subnetting to work.
