What is IP Address?

Most of us have often heard the term IP address from one or the other of our technicians whenever we had a connectivity issue or it was anything related to the internet and just wondered what it could be. This article is going to brief you everything about IP address and what is their significance? An IP address was discovered after the internet users in the early years felt the need of finding out a way that could help them identify the different computer systems so they could be connected together easily whenever it was required. These work just like our telephone numbers. If we dial the same number, we hear the same person.

Similarly, every time you dial the same number, you will get the same computer! Just like our telephone number or our residential address has information about our location, an IP address of a computer has all the information about the computer and it makes it easier to connect to that computer.


The IP (internet protocol) addresses are assigned to any device that is capable of being connected to an internet connection (like a mobile phone, computer, printer, console, GPS etc.) and includes 32-bit numbers that are used for identifying a network and addressing it. Out of all the 32 bits, the numbers that are mentioned are called the ‘octets’ as they have 8 positions and they use the binary system of numbers, i.e. these bits or the numbers can be either 1 or 0 or on or off as they are called.

What is a Bad IP?


A bad IP is just a way of signifying a problem. For instance, if an IP starts with 169, this means that the user will encounter problems accessing the internet. An IP address that starts with 169 is actually a signal given by the router or the modem that there is a problem with the internet services that needs to be resolved.

If you ever face a problem like this, you must seek help from the IT people present to help you at your workplace. At home, turn off your router and unplug it for a couple of minutes before you plug it back and turn it on. If all of the above does not seem to work, you should call a professional who is trained to resolve such connectivity issues where there is a problem between the router and the computer.

IPv4 and

You must have come across IPv4 and very often, whenever the discussions were on about IP addresses. IPv4 is the very first standard recognized for IP addresses and is one of the most common IP address. The IP addresses that we all use at home often range between to and thus are the most commonly recognized.

An IP address is formed with a combination of four blocks of numbers mentioned in a sequence. Every block in the address can have a number anywhere between the value of 0 and 255, which gives every block a possibility of having 256 values in total. Four different blocks with the possibility of 256 different values equaled to billions of unique IP addresses which was more than enough in the early internet era in the 1970s when the popularity and use of the computer were not so widespread. But today with over millions of internet users and businesses having multiple internet connections, we are not even close to the requirement. This is where the dynamic IP addresses and the Subnets come into the picture!

Dynamic and Static IP Address


Dynamic and static IP addresses are self-explanatory to a great extent, referring to the meaning of words. The IP addresses that we use around are all dynamic i.e. that means they are not fixed but are used in rotation. It is impossible that each one of ushave a different and unique IP address. Had that been the case, we would have run out of them long ago. The internet providers assign the IP addresses on a rotation basis which means they assign an IP address that is free, and not the same one every time (which is also impossible). All the IP addresses are not in use at the same time, so when one IP address is not used by an individual, it is assigned for use to the other one.

Just on the contrary, an IP address that does not change at all is a Static IP address. These are generally issued to businesses and are reserved for them. However, for a small cost, an individual can also get one from their internet provider.

What are Subnets?

As the name suggests, a network within a network is called sub-network or subnet. Using Subnets is a great way of reusing IP addresses and thus, solving the problem of IP addresses falling short. The basic idea behind it is to split up the connections itself so that it does not require a new IP address every time. To make it simpler, let’s take an example. We all have multiple computers and laptops in a single house now days, instead of giving each computer or laptop an individual IP address, the internet provider assigns a single IP address to the router used in the house which further creates its own networks and gives all the devices attached to it, an IP address from there itself.

But the problem does not get solved with this! Even after all this, we are short of IP addresses considering the fact that any device that is connected to the internet requires an IP address-Mobile phones, computers, watches, televisions, gaming consoles, handhelds, GPS and everything under the sun that uses an internet connection! Even after dynamic IP addresses and Subnets, we needed a new standard to take care of this need and thus, IPv6 came in.



The IPv6 system of IP addresses gives way to many more combinations, much more than we can use! While theabove mentioned IP addresses used the binary system of numbers (having two values one and zero), the IPv6 uses a hexadecimal system that has 16 values in total (0123456789ABCDEF)! You can imagine the number of combinations that are possible with these (or maybe you cannot!).

An IPv6 address has a total of eight groups of four in hex. To understand it better, check this example- 1234:abcd:5678:efab:9012:cdef:3456:abcd. If we talk in precise terms, the IPv6 system of address will result in 340 undecillion IP addresses that are more than enough and we might never require as many. So with this, the problem of allocation of IP addresses gets solved. - its Uses and Importance: is a commonly sighted IP address. It is actually a private IP address that is used by the two widely used routers-Net gear and D-Link (competitors to Linksys division of Cisco). It is the most commonly used IP address for local router configuration. The network address has not been granted exclusively to the two major router companies but can be used by the other router manufacturers as well, if they wish. If the two routers that are installed on a local network seem to be using the same IP (default) address, it can be easily changed by accessing the router’s administrator console. Plays an important role at the time of initial setup of the router and later, the same is also used to identify any issues related to the internet connectivity with any of the Net gear or D-Link products. The other primary uses include configuring internet connection, to connect to the router, make security settings and perform the general network administrator functions.

How can I Check My IP Address?

  • In case you use Windows
  • Search for CMD on your computer, it will open the command box.
  • Type ‘ipconfig’ and press enter to know your IP address.
  • In case you use a Mac
  • Go to Applications>Utilities>Terminal
  • Once you reach Terminal, type ‘ipconfig’ and press enter to know your IP address.

Using this address administrator you will be able to gain access to the setting page of the router like the broadband router such as the Netgear or the D-Link that is used as default or inbuilt configuration settings from the manufacturer itself. The address of the administration can be changed if you want to whenever you like or want to.

How to Connect Login and Password?

IP address is a private IPv4 address of the network which can be used in the home routers for creating a default gateway. In that kind of router, you have the access to the management console indicating the with the help of the browser on your PC. Any brand of the router or PC in the local network connection due to this very reason the same private ipv4 address can be used. Remember that any of the IP address networks can be used only in one device for ignoring the conflicts of the address.

  • Also, try to disconnect the network firewall for just a moment or try resetting your router to default settings if by chance your password got changed.

Steps to Login IP Address?

The private IP address can be connected to only device network but not for more than one device. The network cannot be connected to two devices at the same IP address at a time sharing the same network. If any situations like that occur then, it is the IP conflict which might affect either the one or both the units that create the instability. Anyway, one IP address can be comfortably used for two different kinds of networks and may be more than that.


Here are some mentioned below on how to Login Address:

  • You will need to reset your router and turn it on and off. After you start the router, then apply the default settings.
  • Most of the time the username of the router is admin or check out at the back of your router where you will find the ID and password of the router.

Final Words:

However using the same IP address by two people within the same network can cause malfunctions. To avoid this problem only one person must use the IP address without any involvement of another user. So make sure you are going the right way. I hope you find this article on how to login IP address helpful for you. Please leave your thoughts bellowing the commenting box.
