How IP Addressing Routing Work

•    IP subnetting and routing
•    Network implementation
•    Routing table
•    Routing protocols

How The Logical Operations Works

CIDR -- Classless InterDomain Routing

Now that you understand "classful" IP Subnetting principles. The reason is CIDR -- Classless InterDomain Routing. CIDR was invented several years ago to keep the internet from running out of IP addresses.

SUBNETTING

Private Subnets

IP ADDRESSING

An IP (internet protocol) address is a unique identifier for a node or host connection on a network. An IP address is a 32 bit (IPv4) binary number usually represented as 4 decimal values, each representing 8 bits, in the range 0 to 255(2 power 8 = 256 - known as octets) separated by decimal points. This is known as "dotted decimal" notation.

Example : 140.179.220.200

It is sometimes useful to view the values in their binary form

Basic Communication Model

Communication is the transfer of a message from one entity, called the source or transmitter, to another, called the destination or receiver, via a channel of some sort.
