Where they’re most needed. However, VLSM can complicate network management due to the varying sizes of each subnet. Network administrators must keep track of these different subnet sizes, which can add complexity to configuration and monitoring tasks. This extra layer of complexity requires more diligent documentation and potentially more advanced management tools to ensure all devices are correctly configured.Subnetting with CIDR:CIDR is a modern method of subnetting that offers flexible allocation of IP addresses without being restricted to the traditional class-based system. It allows network administrators to create subnets of various sizes by using a notation (e.g., /24, /16) to indicate how many bits are used for the network prefix. This flexibility optimizes IP address utilization and improves routing efficiency. For example, CIDR notation allows for the creation of very small subnets when necessary, which can be particularly helpful in managing the IP address space in organizations with diverse needs across different departments.Type of SubnettingDescriptionProsConsFixed-Length SubnettingSubnets are all the same size.Simplifies network management and planning.May waste IP addresses if some subnets need more.Variable-Length Subnetting (VLSM)Subnets can vary in size according to need.Optimizes IP address usage, allowing efficient allocation.More complex to manage due to varying subnet sizes.Subnetting with CIDRFlexible IP allocation without traditional class constraints.Improves routing efficiency and maximizes address space.Requires understanding of CIDR notation, which can be complex for beginners.Subnetting tools and resourcesWhen it comes to managing subnets effectively, several tools can help streamline the process and minimize errors. These tools are essential for network administrators who want to optimize IP address allocation and efficiently manage their network infrastructure efficiently. Subnet calculatorsSubnet calculators are invaluable tools that automatically calculate subnets based on the provided IP address and subnet mask. These calculators help network administrators quickly determine how many addresses are available within a subnet, the range of usable IP addresses,

Table of ContentsIP SubnettingCIDR versus VLSMSpecial SubnetsSubnetting ExamplesIP Subnetting Examples: Example 1IP Subnetting Examples: Example 2Subnetting Example 3Subnetting Examples, Example 4IP SubnettingAs we talked about before, there are two parts in an IP Address. One for them is Network part and the another is Host part. With IP Subnetting, we are adding one more part. This is “Subnet Part”. From the Host part, we borrow some bits and we will use this part for Subnet. In this lesson, we will learn Subnetting with Subnetting Examples.You can test yourself on Subnetting Questions Page!As a basic definion, Subnetting is dividing the network into smaller network groups and by doing this, using the IP Address Block more efficient.For Subnetting, Subnet Masks are used. Subnets masks are 32 bit addresses like IP Addresses. Subnet Masks are used with IP Addresses. The 1s represents the network parts, and 0s represents the host parts.We can show Subnet Masks with four octets like IP addresses (255.255.255.0) or we can show it like /X . Here, for the 255.255.255.0 Subnet Mask, we can use /24. This means that the first 24 bit is full of 1s and it is network part.CIDR versus VLSMIn Subnetting, there are two important terms. These are :• CIDR (Classless Inter Domain Routing)• VLSM (Variable Lenght Subnet Mask)CIDR (Classless Inter Domain Routing) is the term that is used for using IP addresses independent from their traditional IP Classes. In other words, CIDR is using IP addresses without classes.VLSM (Variable Lenght Subnet Mask) is the term that is used for using different Subnet Mask for different sun networks. In aother words, it is the mechanism that allows different Subnet Masks and provide division of a network into sub networks. It is like Subnet of subnets.CIDR is used on the addresses that will advertise to the internet. So, it is used in the Internet Service Provider part. VLSM is used in a company or in smaller networks to use IP address spaces ideally.Subnetting is one of the important lessons of Networking. So, we will show this with more examples.Special SubnetsIn Subnetting some Subnet Masks are used specifically sometimes. These are /24, /30, /31/ and /32.• /24 is the Subnet Mask that is usually used in the local networks by default.• /32 is the Subnet Mask used generally on Loopback and System interfaces.• /31 is the Subnet Mask used on point-to-point links.• /30 is also widely used in Service Provider Networks for point-to-point connections.Loopback Interface is the “virtual” interfaces. There can be many Loopback interfaces in a Router. Loopback Interfaces are used for its “always up and never physically down” characteristics generally. We give these Loopback Interfaces a /32 Loopback IP address.There is also a System Address
