Every device that is connected to the internet has an IP address. This is a unique identifier that allows devices to communicate with each other over the internet. But when it comes to devices that are connected to a local area network (LAN), there are two types of IP addresses: the LAN IP address and the public IP address.


The LAN IP address is used to identify a device on a local network. This means that devices on the same network can communicate with each other using these IP addresses. The LAN IP address is usually assigned to a device by the router, which acts as the gateway to the internet.


The LAN IP address is different from the public IP address, which is used to identify a device on the internet. When a device on a LAN connects to the internet, the router assigns the device a public IP address. This public IP address changes every time the device is connected to the internet, whereas the LAN IP address remains the same.


The LAN IP address is usually a private IP address, which means that it cannot be accessed directly from the internet. This is because private IP addresses are reserved for use on private networks and are not recognized on the internet.



  • 192.168.0.0 – 192.168.255.255 (65,536 IP addresses)

  • 172.16.0.0 – 172.31.255.255 (1,048,576 IP addresses)

  • 10.0.0.0 – 10.255.255.255 (16,777,216 IP addresses)


The LAN IP address is important for setting up devices on a local network, such as printers or servers. It allows devices to communicate with each other and share resources. It’s important to know the LAN IP address of a device if you want to access it from another device on the same network.


In conclusion, the LAN IP address is an important part of any local network. It is used to identify devices on the network and allows them to communicate with each other. Understanding the difference between the LAN IP address and the public IP address is important for setting up devices on a network and for troubleshooting network issues.

A LAN (Local Area Network) subnet is a way to divide a single network into multiple smaller networks. Subnets can be created using a variety of methods, but the most common is by using a subnet mask. This mask determines the range of IP addresses that can be used on a particular subnet, and divides them into groups of nodes or devices.
When setting up a LAN subnet, administrators must first choose the subnet mask they will use. This mask will determine how many IP addresses are available on the subnet, and how many subnets can be created from the overall network. For example, a subnet mask of 255.255.255.0 allows for the creation of 256 individual subnets with up to 254 devices on each subnet.
Once the subnet mask has been selected, the administrator can then assign IP addresses to each device on the network. This is typically done using a DHCP (Dynamic Host Configuration Protocol) server, which automatically assigns IP addresses to devices as they connect to the network. Alternatively, IP addresses can be assigned manually, but this can be time-consuming for larger networks.
By dividing a LAN into multiple subnets, administrators can increase network security and performance. Each individual subnet can be configured with its own firewall settings and access controls, limiting the potential damage that an attack or malware outbreak could cause to the entire network. Additionally, with fewer devices on each individual subnet, network traffic can be reduced, improving performance and decreasing the likelihood of collisions or other issues.
Overall, LAN subnets are an essential tool for network administrators looking to secure and optimize their networks. By dividing a single network into multiple subnets, administrators can better manage network traffic and increase security, improving the overall performance of their LAN.

Wireless transmission power

Wireless Transmission Power - Transmitting Data Without Boundaries


Gone are the days when data transmission was limited by wired connections. With the advent of wireless technology, transmitting data has become much easier and efficient. Wireless transmission power plays a crucial role in this process.
Wireless transmission power refers to the amount of energy that is required to transmit data wirelessly. The higher the power, the greater the distance that the signal can travel. This means that if you have a device with high power, you can transmit data over a longer distance without any loss of signal strength.
But there's a catch. High power doesn't always mean better performance. The transmission power needs to be balanced so that it doesn't interfere with other devices in the vicinity. The Federal Communications Commission (FCC) has set limits on the maximum power output for wireless devices to ensure the radio spectrum is not overloaded with signals.
Wireless transmission power is usually measured in decibels (dBm). A device with 0 dBm of power can transmit data over a very short distance, while a device with 30 dBm of power can transmit data over a distance of up to 1km.
But wireless transmission power isn't the only factor that affects data transmission. The type of antenna used, the frequency of the signal, the location, and the environment all play their part in determining the quality of the signal.
In a nutshell, wireless transmission power is an important factor in transmitting data wirelessly. It helps devices to communicate with each other over varying distances. But just having high power isn't enough; it needs to be balanced in order to avoid interference. As technology advances, we can look forward to even better wireless transmission power that will allow us to transmit data without boundaries.
