Each device connected to the Internet has a so-called IP address of the Internet protocol. There are public and private IP addresses. 192.168.0.1 is the private IP address and standard for certain home broadband routers. Mostly different models from manufacturers D-Link and Netgear.
The difference between public and private IP addresses
The user's computer has a public IP address assigned by an Internet Service Provider (ISP), which is unique throughout the Internet.
The user router has a private IP address that is allowed only on private networks. This IP address should not be globally unique, as it is not a direct access address. In other words, no one can access the IP address 192.168.0.1 and enter the management interface outside the private network.
Who determines the IP addresses? Process description
The Internet Assigned Number Center (IANA) is a global organization that manages IP addresses. First, the type of IP address called IP version 4 (IPv4) is determined. This type is a 32-bit number, which is usually expressed as four numbers separated by a decimal point - for example, http 192.168.0.1. Each decimal number must have a value between 0 and 255, which means that an IPv4 system can host about 4 billion unique addresses.
Private IPs have about 17.9 million different addresses, all of which are reserved for private networks. In this regard, the private IP of the router does not have to be unique.
The router then assigns this value to each device in its network, whether it be a small home network or an enterprise level organization.
Each device within the network can connect to another device on the network using this parameter.
Connection process
Private IP addresses cannot access the Internet on their own. They need to connect through an Internet service provider (ISP). All devices actually connect to the Internet indirectly through the network.
The network to which the user connects is a router, which for the Netgear and D-Link models has an IP address of 192.168.0.1. This device, in turn, connects to an Internet service provider that provides access to the network. Schematically, the connection route looks like this:
User - Router - Internet Service Provider - Internet - Recipient Internet Service Provider - Recipient Router - Recipient.
Public IPs and IPv6
Public IP addresses must be globally unique. This poses a problem for the IPv4 standard, as it can accommodate only 4 billion addresses. In this regard, the IANA Internet Assigned Number Center introduced the IPv6 standard, which supports many other combinations. Instead of using a binary system, it uses a hexadecimal system.
Thus, an IPv6 address consists of eight separate groups of hexadecimal numbers, each of which consists of four digits. For example, abcd: 9876: 4fr0: d5eb: 35da: 21e9: b7b4: 65o5. This system is capable of providing an almost infinite growth of IP addresses, up to 340 undecillion (number with 36 zeros).
IP Address Search
There are several ways to find the IP address. If the computer (or any other connected device) operates on a private network that connects to the Internet (for example, in most homes), each device will have both a private IP assigned by the router and a public IP address.
Search Public IP Address
The easiest way to find a public IP address is to go to google.com and enter “my IP” in the search field. Google returns the client’s public IP address. There are also many other ways, in particular sites specifically designed to look up IP addresses, for example, whatsmyip.org or whatIsMyAddress.com.
Search for a private IP address
When searching for this information, you must follow this algorithm:
1. Press Windows-X to open the Users menu, and then the Command Prompt.
2. Enter ipconfig to display a list of all computer connections.
A private IP address (assuming the user is online) is identified as an IPv4 address. One by which you can connect with someone on your own network.
Change router IP address
The IP address of the router is set by the manufacturer at the factory. But it can be changed at any time using the administrative console of the network router. For example, if another device on the network has the same IP address, the user may encounter an address conflict. In this case, make sure that there are no duplicates.
The order is as follows: go to the administrative console of the router and enter your IP address in the address bar of the browser: http 192.168.0.1.
Any router token or any computer on the LAN can be configured to use this address or a comparable private IPv4 address.
Login to Router Admin with 192.168.0.1
Only one device on the network should use 192.168.0.1 to avoid address conflicts. To enter the console of the router, you must enter 192.168.0.1 in the address bar of the browser.
If the numbers are entered correctly, you will be prompted to enter the appropriate user information. This is the username and password for 192.168.0.1.
After gaining access to the router console, you can make changes to many different parameters. Any network computer can use the password to 192.168.0.1, because it is a private IPv4 network address.
Connectivity issues
If the resource does not work when you enter 192.168.0.1, you need to make sure that all the data is entered correctly. Users often make mistakes by typing 192.168.O.1, i.e. replacing 0 with the letter “O”. Therefore, before entering as admin in 192.168.0.1, it is important to check the spelling of the address. If the resource is still not loading, the router may be using a different IP address, such as 192.168.1.1. For a correct login to 192.168.0.1, it is as important as a valid username and password.
Password to 192.168.0.1 by default
Changing your password regularly is an important step towards securing your network. To do this, log into the control panel of the router. On the admin tab of the router console, it will be possible to change the password to 192.168.0.1. It is important to use a combination of letters and numbers for added security.
