What Is a LAN IP Address and How Does It Work?


If you've ever connected to the internet through a router, you're probably familiar with the concept of IP addresses. Every device on a network needs an IP address to communicate with other devices. But did you know there are actually two types of IP addresses? One is your public IP address, which identifies your router on the internet, and the other is a local IP address, which identifies devices within your local network.
A local IP address, also known as a LAN IP address, is a private address that is only visible within your local network. It's used to identify devices such as your computer or smartphone on the network, so they can communicate with each other and access shared resources like printers or storage devices.
One key feature of a LAN IP address is that it's assigned by your router using a protocol called DHCP (Dynamic Host Configuration Protocol). When a device connects to your network, it requests an IP address from the router. The router then assigns an available address from a pool of addresses reserved for the local network.
Typically, LAN IP addresses are assigned from a specific range reserved for private networks. There are three commonly used ranges: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. These ranges are not routable on the internet, which means devices on your local network cannot be accessed directly from the internet using their LAN IP address.
Overall, a LAN IP address is crucial to the functioning of a local network. Without it, devices on the network wouldn't be able to communicate with each other or access shared resources. DHCP makes it easy for routers to manage IP addresses for multiple devices, and the use of private address ranges ensures that local networks remain secure by preventing direct access from the internet.

Router Reset to Factory Settings


Have you ever experienced a slow or unreliable internet connection? Sometimes it can be incredibly frustrating, especially when you have important tasks to complete online. If your router has been acting up lately, you may want to consider resetting it to factory settings.


Resetting your router to factory settings means that you will be wiping out all of your previous settings and configurations, and returning it to its original state. This can be helpful if you have made some changes to the default settings that may have caused the issues you are now experiencing.


Here is how to reset your router:



  • Locate the reset button on your router.

  • With the router powered on, press and hold the reset button for about 10 seconds.

  • You will notice the lights on the router may turn off and come back on again.

  • Release the button once this happens.


After resetting your router, it is important to set it up again. This means you will need to enter your ISP login and password, and set up your Wi-Fi network name and password. You may also want to update your firmware to ensure that your router is up to date with the latest software security patches.


If you are unsure about how to set up your router again, you can check with your ISP for instructions or consult the user manual for your router.


Resetting your router to factory settings can be a quick and easy solution to fix any connection issues you may be experiencing. So go ahead and give it a try! Your internet connection may thank you for it.

WAN to LAN configuration

One of the most important configurations in a network is a WAN to LAN connection. This configuration is essential in connecting an enterprise's wide area network (WAN) to its local area network (LAN). It is also a crucial connection for allowing remote workers and other devices to access an organization's network from outside its geographical location.


Setting up a WAN to LAN Connection


Setting up a WAN to LAN connection requires the following:



  • A WAN connection: Typically, this is an internet connection provided by an Internet Service Provider.

  • A broadband router: This device serves as the interface between the WAN and LAN.

  • A LAN connection: This is a local area network, which allows multiple devices to connect and communicate within the enterprise network.

  • Firewall security: Installing a Firewall between the WAN and LAN is important to secure the network from external threats.


In setting up the WAN to LAN connection, the first step is connecting the router to the WAN modem. Once this is successful, the router will be able to access the internet via the WAN connection. The next step is to configure the router's WAN port and LAN port. This way, the router can send and receive data from both networks.


Furthermore, setting up the firewall is crucial in securing the network. Firewall installation prevents external threats from accessing the enterprise network. A firewall essentially establishes a barrier between a computer or network and the internet. Hence, unauthorized remote access to the enterprise network can be prevented.


In conclusion, setting up WAN to LAN configuration is a critical component in any network infrastructure. It helps establish a secure network, provide remote access to the enterprise network, and allows data transfer between LAN and WAN networks.

Ethernet LAN

It's hard to imagine life without the internet. It's become a necessity for many of us. But have you ever wondered how the internet actually works? One crucial component of the internet is the Ethernet LAN.


Ethernet LAN stands for Local Area Network, and it is a type of computer network that connects devices in a relatively small geographical area, such as a home, office, or campus. The Ethernet LAN is based on the Ethernet standard, which was developed in the 1970s by Robert Metcalfe and his team at Xerox Corporation.


The Ethernet LAN uses a physical cable, such as twisted pair, coaxial or fiber optic, to connect devices to a network switch or hub. The switch or hub then connects the devices to each other and to the internet. The Ethernet LAN is a peer-to-peer network, meaning that each device has equal access to the network and can communicate directly with other devices.


The Ethernet LAN has several advantages over other types of computer networks. It is relatively easy and inexpensive to set up, and it provides fast and reliable data transfer speeds. It is also scalable, meaning that it can be easily expanded as the network grows.


The Ethernet LAN has played a significant role in the development of the internet, as it has allowed computers and devices to communicate with each other and share information. Without the Ethernet LAN, the internet as we know it today would not exist.


In conclusion, the Ethernet LAN is a crucial component of the internet, and it has revolutionized the way we communicate and share information. It has enabled us to connect with each other, regardless of our location, and has opened up a world of possibilities.
