If you were looking for What does the IP address represent? then your search ends here.

Today, In this tutorial, we’re going to uncovering the mysteries of subnetting by understanding the IP Address So please read complete article carefully.

In the complex world of networking, IP addresses are essential for enabling communication between devices linked to a network. Among the numerous kinds of IP addresses, the interesting frequently jumps out.

This seemingly mysterious string of digits and subnet mask is crucial in the world of networking. We will delve into the world of IP addressing, demystify the significance of, and clarify the idea of subnetting in this blog post.

What is IP Address? Basic Information about IP Address

what is IP address

Let’s understand the basics of IP addresses before delving into the details of

Every device connected to a network is given an IP address, a special numerical designation that enables identification and communication between them. The two main kinds of these addresses are IPv4 and IPv6.

The former, IPv4, is the version currently used in the majority of networks and is composed of four sets of numbers, separated by dots, ranging from 0 to 255 (for example,

What does the IP address represent?

Breaking Down

An example of a special notation used in the IPv4 addressing scheme is the IP address The subnet mask, which is important in subnetting, is represented by the “/29” added at the end. The practice of subnetting involves breaking a larger network into more manageable, smaller subnetworks. Let’s dissect the parts of this address:

The Internet Protocol Address (” in the address’s beginning stands for the host address. In this instance, it identifies a particular network’s distinctive device. To be a part of the same local network, all devices connected to the same network must have the same first three octets (192.168.1).

The Subnet Mask (/29)

A key component that establishes the boundaries between the host address and the network address is the subnet mask.

In CIDR (Classless Inter-Domain Routing) notation, it is shown by putting “/xx” after the IP address, where “xx” represents the number of bits in the subnet mask that are set to 1. In our example, “/29” denotes that the network address takes up the first 29 bits of the IP address, leaving the remaining 3 bits for host addresses.

Subnet range and usable IP address determination

We employ the following formula to determine the subnet range and the quantity of available IP addresses within

Number of IP addresses that can be used: 2(32 – subnet bits) – 2

Since we have 29 subnet bits in our case:

Number of usable IP addresses = 2^(32 – 29) – 2

= 2^3 – 2

= 8 – 2

= 6 usable IP addresses

IP addresses that can be used. The subnet bits can be used to calculate the subnet range. The subnet range in this instance would be:

Subnet Range = 2^(32 – subnet bits)

= 2^(32 – 29)

= 2^3 = 8

Hence, the subnet range for would consist of 8 IP addresses, ranging from to

Working Principle of IP Address

Internet Protocol functions in the same manner as any language. This protocol allows devices to find, send and exchange information with each other. Any computer can communicate with another computer by speaking the same vocabulary.

Typically, the use of IP addresses occurs behind the scenes. To understand how IP address works, read the next paragraph carefully.

  1. Your device connects indirectly to the internet by connecting first to a network connected to the internet, which allows you to access the internet.
  2. You are what you do when you are at it will likely be your Internet Service Provider (ISP) at home. It will be your company’s network at work.
  3. Your ISP assigns your IP address to your device.
  4. Your internet activity will route through your ISP. They then route it back to the ISP using your IP address. They are responsible for assigning an IP address to your device because they provide internet access.
  5. Your IP address can be changed by turning on your router or modem. You can also contact your ISP to have it changed for you.
  6. Your home IP address is unavailable when you went out of the home because your device might be connected to another network (hotel or coffee shop). Accessing the internet will require you to use a temporary IP address. The ISP assigns this at the hotel or coffee shop.

Types of IP addresses

There are many types of IP addresses:

Private IP Addresses

The terms private relate to the network location, and you can use this IP address within the network. Every device that connects via your internet network is assigned a private IP. It includes smartphones, tablets, and computers. It also covers any Bluetooth-enabled device like printers, speakers, or smart TVs.

Each item needs to be uniquely identified by the router, so it requires a way to recognize each other. Your router generates a private IP address that uniquely identifies each device on the network.

Public IP addresses

The public IP address is your network’s primary address. Although each device connected to the web has its unique IP address, they all come under the leading Internet address. Your ISP will provide your router with your public IP address as described above. ISPs usually have large numbers of IP addresses that are distributed to customers. Your public IP Address is the address that devices outside your network will use to recognize your network.

The public IP address has two types, dynamic and static IP address. Dynamic IP addresses change automatically and regularly while static IP addresses remain consistent.

Parts of IP address

The IP address is a unique address that uniquely identifies a device in a local or internet network. It is a 32-bit number.

An IP address is usually written in decimal digits, formatted as four 8-bit fields separated by periods (.). Each 8-bit bit field is one byte of the IP Address. This way of representing the bytes in an IP address is called the dotted-decimal format.

The bytes of the IP address has two parts: the network part and the host part. In the below figure, you can see the details of a specific IP address,

Conclusion denotes a special notation used in subnetting within IPv4 networks, in conclusion. Network managers can efficiently assign IP addresses and enhance network performance by being aware of this format. Subnetting is a potent technology that improves network administration and is essential to the smooth operation of contemporary networks. We can create more reliable and expandable network infrastructures by comprehending the idea of subnetting. The next time you come across an IP address with a subnet mask, you’ll be prepared to solve its riddle and grasp the complexity of the fundamental components of networking.
