What is an IP address? 7 Basic Things to Know About IP Addresses

An Internet Protocol (IP) address is a logical numeric address assigned to every computer, printer, switch, router, or other device that are part of a TCP/IP network.

What is an IP address? 7 Basic Things to Know About IP Addresses

What is an IP address?

An IP address is a basic component on which network design is built; Networking parts cannot link without them. An IP address is a unique address that is used to identify each part of the network. Because IP addresses are logical, they can change. Addresses are similar to a city or city in that an IP address gives parts of the network addresses so you can communicate with other parts of the network, just like sending mail to friends and relatives.

The numbers in an IP address are divided into two parts:

Network part: Identifies the networks to which this address belongs.

Host part: Specifies the exact location.

Explanation of the Internet Protocol (IP Address):

An IP address is the most important component of the networks that connect the World Wide Web together. An IP address is a numeric address assigned to each specific segment that is connected to a network using TCP/IP communication protocols.

Network addresses are assigned by a server (Dynamic Host Configuration Protocol) as soon as any part of the network is connected. DHCP assigns IP addresses using a set of available addresses that are part of the entire addressing system. Although DHCP provides non-static addresses, many devices reserve the static (IP) addresses assigned to this entity forever and cannot be used again.

IP addresses are divided into two types:

Classful IP addressing is a legacy system that divides entire IP address pools into 5 different classes – A, B, C, D, and E.

Classless IP addressing: A system intended to help reduce the high consumption of addresses by design (IPv4).

Types of IP addresses:

Even if you have heard of an IP address before, you may not realize that there are different types of IP addresses, but despite this diversity, all addresses are used for the same purpose. There are private IP addresses, public IP addresses, static IP addresses, and dynamic IP addresses. In addition, each type of IP address can be either an IPv4 address or an IPv6 address.

Private IP addresses:

Private IP addresses are used within a single network, like devices associated with your home network. These types of IP addresses provide your devices with a way to connect to your router and all the other devices in your private network. Private (IP) addresses can be assigned manually or assigned automatically by the router.

Public IP addresses:

Public IP addresses are used on the public Internet and assigned by your Internet Service Provider. It is the main address that your home or business network uses to communicate with the rest of the networked devices around the world, just as when you use the Internet, it provides a way for devices in your home to reach your private ISP. to you, and thus to the outside world, allowing these devices to do things like access websites and communicate directly with other people's computers.

Dynamic and static IP addresses:

Both private IP addresses and public IP addresses are either dynamic or static, which means they either change or don't change. The IP address assigned by a DHCP server is a dynamic IP address, and if not If DHCP is enabled or the device does not support it, the (IP) address must be assigned manually, in which case the (IP) address is called a static address.

What is (IPv4)?

IPv4 is an Internet addressing system that has proven it's worth and has been adopted for many years, based on the employment of 32 bits of numbers that are arranged differently to give different addresses divided into four boxes separated by three points, each cell represents 8 bits and is called the octets, an example of this address (76.240,249.145), and by simple arithmetic, IPv4 has a maximum of 4.3 billion possible addresses. Despite this huge number of addresses, there are not enough IPv4 addresses to accommodate all the computers, smartphones, mobile devices, and other devices that need addresses on the network, this required a new addressing system to meet these growing needs, and IPv6 was the solution.

What is (IPv6)?

IPv6 is a new addressing system developed by the (IETF) and launched in 2012, designed to solve the problem of (IPv4) address exhaustion, it uses 128 processing bits to support approximately 340 trillion different addresses (2 the power of 128), instead of four sets of numbers One to three digits (IPv4), (IPv6) uses eight groups of four hex digits separated by a colon, as in this address 2001:0db8:0012:0001:3c5e:7354:0000:5db1.

The IETF included in its work improvements to (IPv) compared to (IPv4), as the (IPv6) protocol can handle packets more efficiently, improve performance and increase security, and these specifications may last for decades.

Fate (IPv4):

IPv4 addresses aren't going away any time soon, they're still in use, and although new addresses are exhausted, old hardware can still be bought and sold. Perhaps one day IPv6 adoption will reach 100% and no IPv4 addresses will be in use, but that will take a very long time.

How do I know my IP address?

Different devices and operating systems require several steps to find an IP address. There are also different steps to take if you are looking up the public IP address that was provided to you by your ISP, or if you need to find out the private IP address that the router has distributed.

How do I know the public (IP) address:

To find out your router's public IP address there are many ways to find it, but sites like IP Chicken,, make this very easy, they work on any network device that supports a browser On the web, such as smartphones, iPods or laptops, you only have to visit the site in order to display the address.

How do I know the private (IP) address:

It is simple for Windows users, just go to the command prompt and enter the following command (IPCONFIG), and press (enter). As for Android users, they have to go to settings, then (Wi-Fi) and then click on the network used, a new window will appear showing the network information that includes the private (IP) address.
