It is like Subnet of subnets.ĬIDR is used on the addresses that will advertise to the internet. In other words, it is the mechanism that allows different Subnet Masks and provide division of a network into sub networks. VLSM (Variable Length Subnet Mask) is the term that is used for using different Subnet Mask for different sun networks. In other words, CIDR is using IP addresses without classes. These are :ĬIDR (Classless Inter Domain Routing) is the term that is used for using IP addresses independent from their traditional IP Classes. In Subnetting, there are two important terms. You can check Download Subnetting Cheat Sheet This means that the first 24 bit is full of 1s and it is network part. We can show Subnet Masks with four octets like IP addresses (255.255.255.0) or we can show it like /X. The 1s represents the network parts, and 0s represents the host parts.
#ANOTHER TERM FOR SUBNET MASK 32 BIT#
Subnets masks are 32 bit addresses like IP Addresses. In this lesson, we will learn Subnetting with Subnetting Examples.Īs a basic definion, Subnetting is dividing the network into smaller network groups and by doing this, using the IP Address Block more efficient.įor Subnetting, Subnet Masks are used. From the Host part, we borrow some bits and we will use this part for Subnet. With IP Subnetting, we are adding one more part. One for them is Network part and the another is Host part. As we talked about before, there are two parts in an IP Address.
