Which subnet mask would be used if 5 host bits are available?
Each device has its unique IP address no other device has the same address as any other device because the IP address is used for the device identification on an IP network. The IP address has 32 bits and it is broke into the pieces such as the host portion and the network portions with the help of the subnet mask.
The subnet mask is used in the process of subnetting. A question that is common about subnet masks and frequently asked in an exam is: Which subnet mask would be used if 5 host bits are available? However, we are going to discuss the subnet mask and its working. With the help of this, you can easily determine the answer to the question. Without delay let’s begin with the topic!
The subnet mask and its working
A subnet mask divides the IP address into the host portion and the network portion. it can define the range of the address of IPs within the network. The subnet mask identifies the parts of the IP addresses the mask are not visible when the packets are traveling along with the internet, instead they have the destination addresses of the router which has the same address as the subnet mask.
There is two forms of the subnet mask which are listed in the following:
Default subnet mask:
The default mask has been designated for only the single network in the relatively class, the number of the bits is destined for the address class.
Custom subnet mask:
The custom subnet mask as the name suggests it is customized by the administrator and can be accessed or accommodate many networks.
Subnetting
The process of the break the network is the subnetting, the subnet mask work with subnetting. by maintaining the subnet mask the IP address number can be adjusted within the available network. subnetting create multiple networks in classes A, B, C if the subnetting does not happen then you can only use one network in the relatively classes. To form the subnetwork ID, you need to enlarge the natural mask by adding the bits to the host portion of the address.
The common subnet mask of the home is 225.225.225.0 it can be elaborated in a way that the subnet mask gives the authority up to 254 IP addresses to be used in the network .in a simple way 254 devices are connected to the network and access the internet. With the help of the subnet mask, the other devices can determine that either it is connected to the same network or from another network.
Let’s take a look at the example to determine the network portion and the host portion. let’s assume the subnet mask is 255.255.255.0 if we convert it is the binary form then it is 11111111.11111111.11111111. 00000000. while the IP address is 192.168.0.101 and the binary form is 11000000.10101000.00000000.01100101
It is simple to differ the network part and host part the binary form of subnet mask 1 indicates that the same bit of the IP address is the network portion which means the first three octets in the IP addresses is the network part, so the part 192.168.0 is the network part and 101 is the host portion.
The subnet mask of the 255.255.255.224 is used when the 5 hosts bits are available because the 255.255.255.0 has 8 host bits while the 255.255.255 .240 has 4 bits and 255.255.255.128 has 7 host bits.
