192.168.1.1 - 192.168.0.254

192.168.1.1 is a private IP address that belongs to the 192.168.0.0/16 network, which is reserved for private networks on the Internet and cannot be routed on the public Internet without network address translation (NAT).
The router's default IP address is 192.168.1.1, which can be changed by the user through different settings such as DHCP or manual configuration of routing tables and DNS servers in order to connect to a different network (e.g., the Internet).
This section will talk about what an ip address is, what it does, and how you can find your own ip address in order to troubleshoot any problems you may have with your internet connection.

When setting up your home network, it's crucial to know the IP address of your router. In most cases, routers are set to use the IP addresses 192.168.1.1 or 192.168.0.1 as their default gateway. However, some router models may use different IP addresses. To access your router's settings and customize your network, you need to enter its IP address, such as 192.168.1.1, into your web browser's address bar. Once prompted, enter the default login credentials, which are usually 'admin' for both the username and password, to log in to the router's admin panel.

Other common IP are 192.168.1.101, 192.168.1.11, 192.168.1.10, 192.168.l.254 , 192.168.0.254

To be able to connect to the Internet, you need to use devices called Routers. Routers allow a "dialogue" between different networks, in our case between the Internet and our local area network. Routers can be either Wireless (without Ethernet cable) or Wired (with Ethernet cable). Almost all of them use the IP address 192.168.1.1 to connect to the network.
An IP address is a logical number that uniquely identifies a computer on a TCP/IP network.

A router is a layer-3 device of the OSI (open systems interconnection) model that is responsible for routing, or sending, data from one network to another network. The router uses a routing table that resides in its memory to determine the networks that the router knows how to send data to.

How to do this ?, On your computer, you have to set the IP address to 192.168.1.2 (you can choose the last numeric value in a range between 2 and 254) and the Netmask to 255.255.255.0. This way your PC can communicate with the Router since both devices are in the same address class. PC 192.168.1.2 -> 192.168.1.1 Router. To verify that everything is fine, open a DOS window using the CMD command prompt and type PING 192.168.1.1. If you get an answer, it means that everything is ok. Once you have done this, you need to open a browser (such as Chrome, Firefox, Edge, etc.) and type in the address bar the value 192.168.1.1. Subsequentially, you should see the configuration screen of the router; Now you must know the configuration parameters that you have obtained from your Internet provider and set them in the corresponding fields.

Don't forget to change the username and password of your router's control panel. A good rule is to use passwords that are complex enough to be difficult to guess..

These rules ALWAYS apply when creating a Password. Please avoid using the same password for all services, for example, the password for accessing your home banking must not be the same as the password for accessing a forum.

- Create Long Passwords In general, passwords that exceed 8-10 characters are considered strong and typically difficult to crack. Every character you add to your password makes it stronger. However, over the past few years, password cracking technology has advanced significantly. Hence, many WordPress security personnel recommend using passphrases that are 15 characters in length.

Long password: pd$xG56ZhLNrjl4jjNJ4#h (hard to remember)
Long passphrase: Its wolf was white as you know nothing John Snow (easy to remember)
Use a Combination of Uppercase, Lowercase, & Special Characters In brute force attacks, bots are programmed to carry out password cracking procedures. They follow certain instructions, for instance, they'll try to guess the right password by coming up with a combination of different lowercase letters ('˜a', '˜b', '˜c', etc.). Using an easy password like '˜testpass' means they can crack the password after making only a few attempts.

Hence if you use a combination of both lowercase and uppercase characters, it'll take them a long time to figure out the password. However, a really well-programmed bot can try a few million passwords every second. So mixing special characters, numbers, lower and uppercase letters should ideally make the password unpredictable and hard to crack.

Add numeral and symbol - TestPass123$

- Avoid Using Common Words and Publicly Known Details Common words like '˜test', '˜admin', '˜login' are common words that WordPress users tend to use. These are some of the passwords that bots first try out, hence avoid using them. According to an infographic by Splashdata, the top 25 most commonly used passwords are:

Common Sports and Interest like '˜baseball', '˜football', and '˜Star Wars', '˜Princess', '˜Solo' etc. Numbers in Order like '˜87654321', '˜0123456', etc. Letters in Order like '˜abc123', etc. Hackers targeting your website may pick up details from your site and try them out. For instance, if you have a website built around your favorite TV show Game of Thrones, bots will try various combinations of the phrase to break into your sites such as '˜GoThrones123' or '˜gameofthrones123'. To prevent this from happening, design a password that has no mention of anything related to the website.
Securing passwords minimizes the chances of a security breach. But strong passwords are hard to remember unless you have a few tricks up your sleeves.

If you always have wondered what netmask is and what it is supposed to do, I am going to explain it to you in the easiest way possible :) Once you open the control panel of your router, you can read two values, its IP address 192.168.1.1 and Netmask 255.255.255.0. If you notice, these two numeric notations are made up of 4 digits separated by decimal points.

Now before proceeding, we shall rewrite the 4 digits in binary format and obtain 11111111.11111111.11111111.00000000. As you can see, now we have transformed the decimal "255" into binary, resulting in 11111111 while the 0 has become 00000000.

So what is a Netmask? It is merely the number of network devices that can be used :) How do you calculate it? The formula is 2^(elevated to the number of zeros)-2
So 2^8-2=254 here is the number of network devices that can be used. The 2 addresses that cannot be used are 192.168.1.0 (the network identifier) and 192.168.1.255 (the broadcast address), instead, the addresses that can be used range from 192.168.1.1 to 192.168.1.254
The 1s represent the number of networks.

We have understood in the previous paragraph what a netmask is; now we have to see how it is used and when it can be useful. Let's start by saying that usually at home we do not need to use the netmask differently from the usual one (usually you simply leave the default value: 255.255.255.0), but let's consider the following problem. You receive a 192.168.1.0 IP address class, and you are asked to create 6 subnets (perhaps 1 per classroom) each of which must contain 30 PCs.
In this case, the netmask comes into play. This operation is called SUBNETTING.
We have seen that the netmask 255.255.255.0 is equivalent to 11111111.11111111.11111111.00000000, now we have to use the last octet, 00000000, to be able to manage the required 6 sub-networks. To represent 6 subnets, we need 3 bits because 2^3=8, this means that among the 8 bits available we need to use 3 bits, therefore, the last octet shall be converted into 11100000
If we transform 11100000 to decimal places, we get 224. Hence the new netmask 255.255.255.224 allows you to manage the 6 required subnetworks, but for each subnet, how many PCs can we manage? Out of the 8 bits set to 0, now 5 are currently wasted. From here we can deduce that we can manage 2^5-2=30 PCs for each subnet. Keep in mind that when subnetting, not all 254 IP addresses may be used.

Windows PC

• 1. Follow this route
• 2. Beginning > All Programs > Accessories > Command Prompt.
• 3. Currently in the command prompt home window enter following commands one at a time
• 4. ipconfig|findstr/i "Gateway".
• 5. You will certainly see something like this:
• 6. C:\Documents and also Settings\manager> ipconfig|findstr/i "Gateway" Default Gateway .... : 192.168. l.l.
• 7. Thus below your default IP is 192.168.1.1 though it resembles 192.168. l.l.

Unix and Linux

• 1. Open the termina. You can just discover it on the desktop computer or by browsing it in the search bar.
• 2. Click Applications > System Tools > Terminal.
• 3. When terminal opens up, key in following commands.
• 4. ip course|grep default.
• 5. These command will certainly give you result similar to this.
• 6. temo$ ip program|grep default using 192.168. l.l dev eth0 proto static.
• 7. Therefore once more you can see the system offers the default IP address of router 192.168. l.l.

Reset a Password

The first step is to power the router off and then back on. If the problem persists, you can reset your router to factory settings. To do this, find the small pinhole on the back of your router and insert a straightened paperclip into it. After a few seconds, you should see some lights flashing on your router and then it will restart.
There are two common ways to reset a password for a home wireless network:
- Find out what type of security your wireless network uses by looking at the sticker on the bottom or side of your router.
- The first step is to power off your device and then back on again. If this does not work, try resetting it to factory settings by using an old fashioned paper clip in a tiny hole found at the back of most routers (usually next to where you plug in cables).
This should reset all of its settings - including any passwords set up previously.
