You’ve probably heard terms like Private IP Address or Router’s Default IP Address before. 192.168.0.1 is one of the IP addresses that can be considered both private and default IP address. In this article, we are going to talk about 192.168.0.1 address – we are going to explain its purpose and give you some pieces of advice on how to use it. We will also provide you with some info on IP addresses, their classification, and differences between private and public IP address. Furthermore, we will explain the term default gateway (or default IP addresses) and in the end, we will mention some of the manufacturers that use this IP address as a default for their routers. Hopefully, you will have a much better understanding of 192.168.0.1 IP address and better understanding of IP addresses in general after reading.

IP Addresses and Their Classification
Every device on the internet must have its own unique address in order to communicate with other devices on the network. You can think of it as of your device’s ID. Just like every person has unique ID, every device has IP address.
In 1973, Internet Protocol was designed in order to define the rules of assigning IP address to every device. According to this Protocol, every IP address consists of 4 octets (4 groups, each made of 8 bits). These addresses are translated into real numbers (into decimal notation) for easier use and that’s the number you can see at the bottom of your router, for example. There are four numbers, ranging from 0 to 255, separated by dots (192.168.0.1, for example). If you don’t understand why is there only 256 possible values for those numbers, the explanation is pretty simple – when you ‘’translate’’ eight 0s from binary to decimal notation you get 0, and when you translate eight 1s from binary to decimal notation you get 255. The number of possible combinations of eight 0s and 1s (when you don’t have to use four 0s and four 1s, but you can have five 0s and three 1s, or two 0s and six 1s, or even eight zeros or eight ones) is 28 (256 or from 0 to 255). This type of assigning IP addresses is called IPv4 and it served us well for more than 45 years and it is still in use.
The problem with IPv4 is limited number of IP addresses. This number is huge (especially when you look at it from 1973 perspective). There are almost 4.3 billion IPv4 addresses and that was more than enough for some time but no one could predict how big internet is going to be. With incredible number of devices and increasing number of people living on Earth (more than 7 billion currently), this amount of available IPv4 addresses won’t be enough in 10 years. That’s why new protocol was introduced. It’s called IPv6 and it’s similar to IPv4 but now we have 128 bits (not 32), and they are arranged in 8 ‘’words’’ (word is a sequence made of 16 bits). This new protocol offers incredible number of 340 undecillion (340*1036) IP addresses which is more than enough for years to come.
IPv4 addresses are still in use (and it will be for some time), and the one we are going to talk about (192.168.1.0) is also an IPv4 address. However, you should know that IPv6 is the future.
The rest of our story relates only to IPv4 addresses.
Since 4.3 billion is really big number, some classification of IP addresses had to be done. All the addresses are classified into 5 groups. Class A IP addresses are reserved for the biggest networks and multinational companies, Class B is reserved for Internet Service Providers and large companies, Class C is reserved for smaller companies, while class D and E are for multicast and experimental purposes respectively. If you want to find out more about blocks of IP addresses that each of these classes includes or you want to know more about the maximum number of networks and hosts within every class, you can read one of our previous articles on 192.168.1.1 IP address. You will find all the details there.
Public and Private Addresses
There is one more classification within this existing classification. This one is pretty much self-explanatory. Each of the first three classes (A, B, C) can be divided into two more groups – public and private IP addresses. The majority of addresses within each class are considered public which means that you can route them on the internet, but there are some blocks that are unrouteable on the internet and they are reserved for private use and for closed intranet networks within companies. The most ‘’popular’’ (or recognizable) block is the one inside Class C (192.168.0.0 to 192.168.255.255) since many home networks are connected to the internet through these IP addresses (192.168.0.1 is one of them). You can read about other blocks in the article we’ve mentioned previously.
Since the number of private addresses is very limited and you need one to access the internet, Internet Service Providers came up with solution – they made bunch of subnetworks (smaller networks within larger one) by using subnet masks. That way, they enabled using one IP address by many users. That wouldn’t be possible if all the users were within the same network because two users with the same IP address within that network would cause something called ‘’IP conflict’’ (their IP addresses have to be unique in order to communicate with each other). By making bunch of smaller networks (or subnetworks) ISPs enabled using one IP address multiple times by multiple users (it practically gets recycled). Many people use one of only a few IP addresses (gateways) to go online and that’s how maximum exploitation of IP addresses is achieved. This is, by the way, the thing that prolonged the life of IPv4.
If you want to read more about subnetting and subnet masks, you have everything explained here.
Router’s Default IP Address – Default Gateway
We have mentioned this previously, but it doesn’t hurt to repeat it once more. In order to hook up to the internet, you need router. Every request or package of data that you send from your computer has to go through router before going online. That’s why we consider router a gateway to the internet. Every router has its own default IP address and it uses it to hook up to the internet. Let’s say you have 3 or 4 or more devices and each of these devices has its own IP address. In order go online, all these devices communicate with your router, and this router masks other IP addresses with its own IP address. That way, the number of different IP addresses within one subnetwork is reduced, IP conflicts are avoided, and maximum utilization of one IP address is achieved. One of these ‘’default gateways’’ or router’s default IP addresses is this specific address from the title – 192.168.0.1.
Which Router Manufacturers use 192.168.0.1 As A Default Gateway for Their Routers?
192.168.0.1 is, along with 192.168.1.1 and a few others, one of the common default IP addresses for routers. Some of the most popular router manufacturers using this IP address as the default gateway are D-Link, Linksys, Motorola, Netgear, Siemens, Sitecom, Tenda, Thomson, TP-Link, Trendnet, ZTE, 2Wire, Card King.
How to Use 192.168.0.1 and How to Set Up Your Router?
This IP address (as well as any default gateway IP address) is used for adjusting different aspects of your internet connection through router setup. In order to enter router setup, you should go to your browser and enter 192.168.0.1 in the address bar. If that’s your router’s IP address, you will be redirected to login page and you will have to enter the correct username and password in order to enter router setup dashboard.
You can use this dashboard to change all kinds of stuff related to your connection – you can set new SSID (which is the name of the network you’ll see on your PC or phone when trying to connect to the internet), you can change firewall settings (add some exceptions to firewall rules), change username or password (but be careful with this – you have to remember new password and username if you want to access the setup dashboard again in the future).
How to Find Your Router’s Default IP Address?
There are many ways to check your router’s IP address on every operating system.
If you are using Windows, you can type in ‘’ipconfig’’ in CMD Prompt and you will get that IP.
If you are using Linux, you can use command ‘’netstat -r’’, type it in Terminal, and that’s it.
If you have Mac OS, you can check router’s IP by entering command ‘’netstat -rn’’ in Terminal.
You can find detailed explanations in that article we’ve mentioned previously.
What to Do If You Don’t Know or If You Forget Router’s Username or Password?
In order to enter router’s setup dashboard, you have to know the right username and password. If you don’t know what are router’s username and password, you can do a couple of things:
- Check user manual and find default username and password
- Look at the back or at the bottom– some routers have labels with IP and MAC addresses written on them along with default username and password
- You can type in some of the most common default usernames and passwords. The most common usernames are: admin, Administrator, Admin, or blank (don’t write blank, just leave the field blank). The most common default password is admin but there are some routers that are not password protected by default and you can just leave the password field empty. By trying some of these combinations you are probably going to enter the setup page.
If you have accessed router’s setup page in the past and you’ve changed the password or username but you can’t remember it now, don’t be afraid. There is always a solution. If you can’t find or remember your username or password, you can always reset router. If you’ve done some extensive adjustments in the past, you won’t be happy with the original settings but that’s the only solution and you can always make these adjustments again.
The reset button is usually at the back, it is labeled and it is inside a pinhole, so you will need a pen, or a needle or some other sharp and thin object to press it. You have to hold it for 10 seconds, and after that, all the settings will reset to the original. After that, you can use default username and password to enter the setup dashboard and you can start configuring your router.
