So what are IPv4 addresses?

So it's an undeniable fact that the internet has an important place in people's lives.

You must be on and off the internet during the day, but you definitely use the internet for your needs

more than just for browsing.

But did you know how the internet has provided you type the name or the address into your browser?

The address that you want is presented to you.

The technology that enables this is called IPv4.

Let's learn what it is in IPv4 detail.

What is IPv4 Internet protocol, or IP, is the basic technology that enables devices to connect to

the internet.

It allows devices used on the internet to send messages and data to each other.

When you want to connect to the internet device, such as computers, laptops, mobile phones, tablets,

this technology assigned to numerical IP address IP addresses are vital for the internet infrastructure.

Information flow between computers cannot be provided without IP addresses.

IPv4 is version four of the Internet protocol.

It's been in use since 1983, and it's the version used by devices that connect to the internet.

This version gives a private IP address for each device.

It will access the internet if your home address shows where you live.

The IP address shows what device you are using.

What are IPV four DNS servers?

Those who have a little knowledge of computers and the internet often have heard of the concept of IPV

for DNS, DNS or domain name system is a system that translates and redirects site names to real IP

addresses.

Thanks to this system, you can browse the internet quickly and comfortably.

A DNS server is a computer server with a database of site names, two IP addresses.

Most DNS servers are owned by internet service providers.

They just open the servers to their customers.

However, there are free servers available.

For example, Google's preferred DNS server, which is the most used internet search engine, is 8.8.8.8,

and the other DNS server is eight Dot eight Dot 4.4.

So how does IPV for work?

IPv4 consists of 32 bits, so it consists of four numbers of eight bits, the numbers that will create

the IP address vary between zero and 255.

So it generates two to the thirty second, that's four billion, 294 million, nine hundred sixty seven

thousand two hundred ninety six possible odd addresses.

This possibility assigns each user an IP address between the numbers 0.0.0.0 and 255.255.255.0 255.

Examples of IPv4 addresses.

IP classes consist of four types of addresses A, B, C, D and E.

For now, let's briefly look at these classes.

Class A address is designed for large networks with many users.

We can give an example of 49 Dot, 19 Dot 22 Dot 156 IPV four.

Class B address first to walk debts are used to define the network.

The other two octet are used to address users.

All addresses between 128 and 191 are Class B.

One take 0.7 5.10, not one 10 is an example of a Class B IP address.

The Class C address, the first three OK, debts are used to identify the network.

The last octet is used to address users.

All addresses between one, nine, two and two to three are Class C.

One nine, two one six eight not one zero one zero five is an example of a Class C IP address.

Class D addresses our IP addresses that are used for multicast all addresses between two, two four

and two three nine are Class D.

For instance, we can give the IP address two two four zero zero zero through 39 that 255.255.255.0.

Class IP addresses are not used on the internet.

It has been stored for research and future use.

Do for 0.0.0.0 through two five four two five five two five five two five four is an E class IP address.

So how to learn IPv4 if you're doing extensive information exchange on the internet, how will you learn

IPv4 because it'll interest you?

There are two ways to find out your IP address.

The first is to find an IPv4 address with a skimmed command, and the second would be to find it through

the control panel.

Using one of these two ways, you can find out your own IPv4 address.

You can even learn your Mac or physical address and the DNS server, as well as your IP address.

How to find your IPv4 address.

You open the start or run command from the taskbar to learn the IPv4 address connected to your computer.

Type seemed in the search bar that appears on the screen.

A black screen will appear in front of you in the bottom line type IP config into the command that says

see backslash users backslash, believe, backslash and enter.

This part may vary depending on the name and the language of your computer.

The Windows IP configuration page appears on the screen.

The IPv4 address under the Ethernet Adapter LAN connection line is your IP number.

If you want to know your IP address from control panel, follow control panel to network and internet

to network and sharing center to connections to details, you will see all the information about the

IP.

So why do you configure IPv4 settings?

When you access the internet with your device, IPv4 automatically provides you with an IP address.

You do not take any action for it.

If you are using the internet effectively, if you are doing international transactions, if you want

to use a secure IP address, IPv4 settings will be important for you.

If you were on the internet with a corporate identity, it is important that you have a private IP address,

otherwise you will have to use a shared address like other users.

Along with the IP address, the system automatically assigns you DNS servers.

But since these automatically assigned servers do not recognize some sites, you cannot log in.

You can change the DNS servers that allow you to enter these sites.

IPv4 DNS server.

Well, that's the lesson.

And now you've learned what an IPv4 address is, how you can learn your own and maybe how to configure

it.

So I hope you learned a lot because we're going to build on that in the next one.
