Setting the stage. –Why the mastery of IP Subnetting skills is so important in the real world. –What we knowor think we know, can be a factor in our mastery. ? Key elements in successful execution of the subnetting procedure. –Creating a MB-Key, identifying the need in the network, and using your thumbs (and other digits)
How to Master Subnetting www.gns3vault.com. Page 3 of 103. Introduction. Binary and hexadecimal numbers are a complete mystery for many of us. Often we don?t find it really interesting because on the internet there are plenty of “subnet" or “binary" calculators where you can easily calculate from decimal to binary to

This document provides?basic information needed in order to configure your router for routing IP, such as how addresses are broken down and how subnetting.
Hardware Addressing. A hardware address is used to uniquely identify a host within a local network. Hardware addressing is a function of the Data-Link layer of the. OSI model (Layer-2). Ethernet utilizes the 48-bit MAC address as its hardware address. The. MAC address is often hardcoded on physical network interfaces,
We care because that's how we do routing. IP routing is based on a simple “next hop" model: Is the destination address ON my network or. NOT? If it is ON my network, send it directly. If it is NOT on my network, send it via a router. To match network numbers, you must know what part is network and what part is host
Every IP address must be accompanied by a subnet mask. By now you should be able to look at an IP address and tell what class it is. Unfortunately your computer doesn't think that way. For your computer to determine the network and subnet portion of an IP address it must. “AND" the IP address with the subnet mask.
