What do you understand about a Subnet Mask? |
|
Answer» The number indicating the range of IP addresses that can be used within a network is called a Subnet Mask. Sub Networks or subnets are assigned to them. These SUBNETWORKS are a collection of LANs that are linked to the internet. This Subnet mask is a 32-bit value that MASKS the IP address and divides it into two parts: the network address and the host address. Subnet Masks are made by assigning all network bits to "1" and all host bits to "0." There are two network addresses that can't be assigned to any host on the network: "0" and "255", which are assigned to the network and the broadcast address, RESPECTIVELY, and HENCE can't be assigned to anyone. |
