192.168.l.2 is a private IP address. It can be a default IP address for some routers which are typically sold in markets outside of the USA. If it is not a default IP address for a router then it is usual IP address assigned to other devices of some particular local network.

Why Is IP Address Important?

IP addresses have very important role in telecommunication. Without them, the flow of data between some interconnected devices would be impossible. Simply, the data wouldn’t be able to be supplied if there isn’t some mark of potential destination. IP addresses represent these marks.

Every device that is connected to some network must have an IP address in order to be able to communicate with other devices. In every transfer of information, the IP address of the sender is equally important as IP address of the receiver. Both addresses have to be taken into account.

It is very important that each IP address within some network has to be unique. In other words, for a network to be workable, it is impossible that there are two identical IP addresses for two different devices. If this situation still occurs then there emerges the problem of so-called IP address conflict. This problem is one of the most common causes of network crashes.

As it is surely obvious by now, IP addresses are very similar in their specifications to regular, postal addresses. So, for the understanding of IP addresses, it could be useful to think about the two in a similar manner.

Manual IP Address Assignment

Now when it is clear what IP addresses are, there emerges an important question: how the assignment of IP addresses works? We can make difference between manual and automatic IP address assignment.

The manual IP address represents the way of IP address assignment that is performed by an administrator of the network. The administrator can choose by himself/herself what IP address will be assigned to which device in the network. That can be done by filling in the number of certain IP address into a setting configuration screen of the device.

For example, you can assign IP address 192.168.l.2 to your network router in following way. First, you need to log in into your router’s account page. After that, you should find a basic setup page and go to it. There you will find information about the network. Into the LAN IP address bar, you should write 192.168.l.2. Now you can press the Apply button and that’s it.

There are few issues with this way of IP address assignment. First, if you do that manually you should be perfectly careful in order to avoid IP address conflicts. It is absolutely necessary to know exactly what IP addresses you have assigned to which device. This can be a pretty difficult job if there are many devices connected to the network.

Second, manual assignment of IP addresses represents the static (fixed) assignment. This means that IP address which is assigned to some device is permanently tied to it. And this could be an issue because that particular address can’t be used again for some other device. If the administrator has forgotten that some IP address has been already assigned and tries to assign it to some other device then there will emerge the problem of IP address conflict.

Automatic IP Address Assignment

On the other hand, the process of IP address assignment can be done automatically by a router. It is only necessary that the router and other devices which should get an IP address support DHCP (Dynamic Host Configuration Protocol). DHCP is software that makes the process of IP address assignment possible.

First of all, the router takes one IP address for itself. After that, it assigns IP addresses to other devices that are inside the network area. Usually, it assigns the first available IP address from the range of all IP addresses. And that’s why, if is the IP address of a router, 192.168.l.2 is the most used IP address for other devices.

Automatic IP address assignment is dynamical one. This means that IP address is only temporarily assigned to some device. If it is not active for 3-4 days (so-called lease period) its IP address go back to pool and waits to be assigned again. This way of the assignment is better than the manual for two reasons. First, it is more economical which means that it saves IP addresses. Second, it more effectively avoids possible IP address conflicts. However, the router will not check whether some IP address was already assigned manually and this fact can lead to IP address conflict. That’s why it is safer not to assign any IP address manually at all.

How to Know Whether 192.168.l.2 is Router’s Default IP Address?

If you are interested from any reason to know which IP address is used by your router, you can do it very easy.

Firstly, you can identify the default IP address of your router just by looking at the console. Generally, it is written on it. If you can’t find this information, you can instead check what a default gateway is. This could be found on the setting page of any device connected to the network. If you see 192.168.l.2 then it is your router’s IP address.

Secondly, you can find router’s IP address very easily if your PC (which using Windows) is connected to the local network. You just need to follow these steps:

  1. Press Windows-X, open the Power Users menu and then click Command Prompt.
  2. Enter Ipconfig where you can find all connections of yours computer.

There you will find the section Local Area Connection. Look at the number beside “Default Gateway” and if it is 192.168.l.2 (or any other private IP address) than it is your router’s IP address.
