IPv4 is the most widely used version of the Internet Protocol. It defines IP addresses in a 32-bit format, which looks like 123.123. 123.123. Each three-digit section can include a number from 0 to 255, which means the total number of IPv4 addresses available is 4,294,967,296 (256 x 256 x 256 x 256 or 2^32).Let's dive a bit deeper in knowing the IPV4 addressing formats.

The essence of computer networking is to transport packets from one machine (source) to another (destination). In the current modern age, with high speed networking and the internet growing to a vast global network of various devices, we tend to take things such as how a simple packet of data containing your request to fetch the content at, say, www.crio.do, moves from your computing device to the server where Crio's website resides.This MicroByte explores the basics of packet routing and demonstrates the concept behind traceroute - a popular utility used to find some of the paths taken by a packet to reach a destination.
