The term IP address needs no introduction. Everyone who uses the internet is familiar with it. is one of the commonly used IP address which we come across frequently. We are mainly concerned about accessing the internet; therefore not many of us want to get into the technical aspects. But there are a few individuals who are enthusiastic to probe deeper. They prefer learning about the ins and outs of the infrastructure or the backbone of the internet. For the curious minds, we are here to quench your thirst. Read on to know in details about the IP addresses and how they work.

The Basics of IP Address IP

Once you finish reading this, you should be able to understand the functionalities of the IP address rather easily. We suggest even those who are least interested in knowing about these aspects will also be benefited. The knowledge will help you to diagnose and rectify some of the underlying connection problems and setting up your connection. The 192.168.o.1 IP address is categorized as a private IP address. You will generally find this
address to be associated with the Netgear and D-Link routers.

But why on earth we need such an address, you may ask! Precisely, identification of the computer systems that are
connected with each other is essential. To make things simpler, you can compare this number with that of the phone number. Providing your number to others would help them reach out to you when they dial your specific number. Similarly, the IP address is the specific number for a computer; additionally they also pack some information on the location of the computer. The IP addresses can be assigned to any device which has the capability of connecting to a network. They are 32-bit numbers, and each block is referred to as an octet, and it uses a binary system.

Checking Your IP Address

Since you are reading this, albeit being online, your computer should also have an IP address. Feeling curious to check the address?

It is super-easy. Assuming, you are using the Windows OS, type CMD on the search window from the Start Menu. A command box will appear type in “ipconfig” and press Enter; your computer’s IP address will be in front of
your eyes.


Using Mac OS? No problem, you can also check the IP address. Simply navigate to Applications >> Utilities >> Terminal and then type the same command, i.e., “ipconfig,” you will get the IP address of your Mac computer.

Decoding the IP Addresses

The standard for the networking method is IPV4 (Internet Protocol Version 4). is one such example of an IPV4 address. Generally, you will find the ranges of IP addresses to vary in the range 192.168.o.1 to for our home-based computers.

As you can see, there is a sequence of four blocks of numbers in the IP addresses, you may not know this, that each of these blocks can contain a value between 0 and 255. Some of the IP addresses are restricted and are only used as an external IP address. Notable examples include the address and Thus, the IPV4 has the provision of four billion unique IP addresses. Do you think this is a vast number?

Well, you would find it hard to believe the advent of the IPV4 was nearly 38 years ago. Who would have expected such an exponential growth of the internet in the coming days?

At the present day, the world population has swelled to over six billion, add to that the number of home and business internet connections. The four billion addresses are just a fraction in comparison to the demand in the current scenario. To manage the enormous market, this has been further broken down into dynamic IP addresses and subnets.

We will be telling you about this in a short while.

Uses and importance of Uses

As mentioned earlier, we frequently come across the IP address. It is a private IP address which is defined by the Internet Assigned Numbers Authority (IANA) and is usually used by the router manufacturing companies like D-Link and Netgear.

Understandably, both these companies manufacture a huge number of routers. The IP address is not exclusive for these two companies, as there is the provision of other router manufacturers to select and use the same IP address if they wish to do so. So for instance, if any other router uses this address in the same network, it needs to be changed.

The necessary changes can be made by accessing the administrator’s console. By navigating to the default IP of the routers the primary setup can be done. Additionally, if there are any problems with the network connectivity, it can be identified with this IP address.

The modern variants of IP addresses

Dynamic IP addresses: 

Dynamic IP Address

In the current scenario, it would not have been possible to work if everyone had their IP. Thus, the advent of dynamic IP address became indispensable.

Now, the internet providers assign dynamic IP addresses. Whenever a specific IP address is not in use, it can be assigned to you; thus your IP address is never the same.


As the name suggests, a subnet indicates a sub-network. By the help of subnets, the connections are split for the sake of re-using the IP addresses. Yet, the present era has witnessed an exponential growth in the number of devices that can connect to the internet.

Thus, it became necessary to introduce a new standard. Thus the IPV6 standard came into existence



As we keep on emphasizing, the four billion IP addresses are far too less in comparison to the growing demand, and the IPV6 uses a hexadecimal system which allows endless possibilities.

We are not going to confuse you with the mathematical jargon, but you should know with the IPV6 a whopping 340 undecillion IP addresses can be supported.

How Does work? IP

The IP address as you already know is a private address. The IANA predetermines the ranges of IP addresses that are going to be reserved for private use. Thus, no other device using a network will be able to connect to the internet with the 192.168.o.1 address. Similarly, other devices in the network which does not belong to the same local connection will not be able to connect to the computer using a private address. Here comes the essentiality of using a router which helps them to connect to the internet. is categorized as a Class C network address. Since it can only be identified in the network where it is currently working, the 192.168.o.1 is considered a private IP address. Therefore, whenever you introduce a new device on your network, you should ensure its default IP address is not in use.

Setting up the Routers with

You need not be a tech-savvy person to use the IP address for configuring the setup of your router. You have a host of options to play with once you access the router setup page that includes changing or setting the wireless security mode, changing the SSID, and to set up the network security keys. IP Login

Here are the steps:

  • The first step would obviously be to switch on your router.
  • Now, you should connect your computer with the router. Such connections are typically made with the help of an Ethernet cable. Do remember, when you are accessing the configuration page of the router to make the necessary changes, this has to be done in the hard-wired connection mode only. Routers will not support the wireless connections.
  • Open the browser and type 192.168.o.1 in the address bar.
  • The page will ask you to supply the username and password. Usually, not many people are prone to changing these credentials. The default username and password, in this case, would be “admin” and “password” respectively. Some other password variants may include “1234”, “admin” or the “password” where the pis capital.
  • A successful login should open the configuration page. You can select the appropriate settings and make the necessary changes. When you are done, click on “apply,” and it is done.

Unable to connect to

  • Commonly, many people have reported the inability to connect to The simplest solution is to reboot your router. So, you can turn it off and on again.
  • If the problem persists, you can try and reset your router to the factory settings. Understandably, you are going to lose your custom settings by doing so. But, you do not have any other way out. Resetting the router can be done by pressing the reset switch for a while until the router light blinks. The entire process should not take more than ten seconds. By any chance, if you have forgotten the username and password, resetting can help. By resetting, your router will use the default credentials which you can change later.
  • Even after resetting your router, you are unable to access the page; it is possible there has been a network change in your router’s IP address. In this scenario, you can make a network scan to solve the problem.

Bad IP addresses

Now, what is a bad IP address? In any situation, if you notice, your IP address commences with the 169, this would mean there is some problem with the router. Resetting the router often helps in such scenarios. If you continue to see the same IP address, you can be sure there is some problem between the computer and the router.


Now, that you have learned the basics of IP address, aren’t you feeling enriched with knowledge Whenever someone needs to configure the routers and thinking about calling a tech expert, you should now be able to solve the problem for them.
