Understanding IPv4 Addressing System History and creation, was one of the most interesting subject I worked on. Briefly, when the Government, Colleges, and Institutes needed a reliable way of computer communication among its agencies, Mathematicians and communication Engineers gathered together to come up with Addressing Systems based on Binary Base 2 System. I found it… Continue Reading …
Understanding Class A Network IP Addresses
As mentioned under Understanding IPv4 Addressing System, human prefer to deal with Decimal over Binary System. Understanding Class A Network IP Addresses explains why the previous article suggested to use 256 decimal to represent the Binary Network 0.0.0.0 (The ONE Big Pie) as base to divide, therefore, decimal 256 can be divided as needed. Let’s… Continue Reading …
Understanding Class B Network IP Addresses
Continue dividing, Understanding Class B Network IP Addresses will go through dividing the 128 remainder further to smaller Networks, which will lead to Classful B Networks, however, there will be another remainder as well to create Class C Networks. So, If you haven’t followed the process from the beginning, I recommend you read Understanding IP… Continue Reading …
Understanding Class C Network IP Addresses
This article will finalize what I called the First Division of IPv4’s Space. Understanding Class C Network IP Addresses will show you how dividing 64 by 2 formed the last Unicast Classful C Networks. As mentioned in previous articles, there are Unicast, Multicast, and Broadcast IP Addresses. Class A, B, and C Networks’ addresses are… Continue Reading …
Understanding Classful Network Mask
Understanding Classful Network Mask explains why every Network IP device must belong to a Network Address, and how every Network Address must have Netmask Address. Therefore, to communicate with ccnahub.com’s web server, PC1 or its Gateway must know the Web Server’s IP Address, Network Address, and the Netmask which will point to the Network Portion… Continue Reading …
Understanding Classless Subnet Mask
Why Understanding Classless Subnet Mask is a key stone? In my previous articles, I mentioned about how it all started with One Big IP Space, then how the Engineers divided the IP space to Classes A, B, C, D, and E. Besides, how the Engineers identified each Classful Network by setting for each Class what… Continue Reading …
Understanding Classless Subnetting Concept
Let’s dig into Understanding Classless Subnetting Concept. In my previous article Understanding Classless Subnet Mask, I have explained briefly why in the 90’s a new approach to distribute the IP Space Classless Subnet Masks was required to replace Classful Masks. In this article, I am going to dig deep into this approach for Subnetting (dividing)… Continue Reading …
