What is an IPv4 Address?

An Internet Protocol version 4, or IPv4 address, is an identifying number assigned to devices on a network using the Internet Protocol for communication. It's the most widely used form of IP address today, and it's made up of four sets of numbers separated by decimal points.

Your IPv4 address is what allows you to access the internet from your computer. Without it, you wouldn't be able to access websites, send emails, use instant messaging and do other online activities. Every device that connects to the internet needs an IP address.

An IPv4 address consists of 32 bits (four octets) and can range from 0.0.0.0 to 255.255.255.255 by convention. Each set of numbers corresponds to different components that identify who or what is on each side of a connection. The first three octets typically refer to a specific geographical area like a city or country; the fourth octet takes care of allocating specific addresses within each geographic area for multiple computers located there.

You may require several different IPv4 addresses if you work in an office and use multiple computers connected to one network over the same broadband connection - such as if everyone was using the same email server or file server on the local network - as well as when hosting multiple websites from one server but have separate IPs for each site (this process is known as virtual hosting). The four values within addresses can normally range between 0 and 255, which means there are nearly 4 billion possibilities available in total via every combination shuffled within those four segments giving more than enough scope where a single site can feature 256 unique addresses between 0 and 255 in each section (256^3 = 16,777,216 possible combinations).

It's important to note that IPv4 has become increasingly limited due to growing demand for new websites and online services in recent years because only 4 billion IP addresses can be created in this space so new solutions had to be brought about in order for more people/networks/websites etc., with different amounts of traffic could connect without significantly affecting available resources through overcrowding (IPv6 would be introduced shortly after).
