Do you want to learn about IPv4 subnetting and what it means for Internet users? Then this article has been written specifically for you as it will be used to discuss IPv4 subnetting.<\/p>\n<\/blockquote>\n

If you are a network admin or you want to create your own proxy server, there is a high chance that you will at some point carry out IP subnetting in other to have your network divided into manageable units in other to simplify your workflow and reduce traffic congestion. IP subnetting is not only peculiar to proxies and office networks.<\/p>\n

Any computer network that follows the Internet protocol such as your LAN and WAN, including the Internet at large, all benefits from IP subnetting. Usually, when buying many IP addresses, what you get is an IP subnet that will contain a defined number of IP addresses depending on its mask. It is important you learn about IP subnetting in other to know how to effectively use them to your advantage.<\/p>\n

In this article, our focus is on IPv4 subnetting. You will learn what IPv4 IP addresses are, IPv4 subnetting, and how to calculate subnetting in IPv4. Also important to learn is how web services make use of IP subnets for preventing spam \u2013 and how to evade such.<\/p>\n\n

<\/span>What is IPv4 Subnetting?<\/strong><\/span><\/h2>\n

\"IPv4\n<\/picture>\n

IPv4 subnetting is the process of dividing IPv4 IP networks into blocks or subnetworks so that each subnetwork (subnet) will have IP addresses that are identically in the same bit group. Each of these is known as an IPv4 subnet.<\/p>\n

An IPv4 subnet is a logical subdivision of an IP network. IP addresses that belong to the same subnet are addressed with an identical most-significant bit-group. This leads to the logical division of an IP address into a network number and host identifier. The number of IP addresses in a subnet when subnetting is carried out depends largely on the subnet masks, which many see as the type of the subnets.<\/p>\n\n

<\/span>Why Carry out IPv4 Subnetting?<\/strong><\/span><\/h2>\n

There are a good number of reasons why you will want to carry out IPv4 IP subnetting. If you already have your own use case, you can either briefly check this section or move to the next section for the real deal. However, if you do not have a use case in mind, then the below are some of the reasons why you will have to carry out IP subnetting.<\/p>\n
