How To Reserve IP Addresses For a Device on a WiFi Network

The world is evolving every day on the basis of new technology, getting more and more digitalised, making it easier for people to interact with each other regardless of the distances and share information all around the world. People can communicate with each other on a large geographical scale and be possible due to the emerging field of networking. As networking helps the computer communicate with one another based on a set of common communication protocols (rules) over digital interconnection, one of these protocols to connect computers into a network to share data is WIFI.  Wireless Fidelity or WIFI is now a day one of the basic necessity of life, and without it, the modern generation cannot cope with the world. Wifi acts as a fuel or core ingredient to perform various everyday tasks. We may use WIFI in our everyday life but still doesn’t know how it works or basically what it even is. Wifi belongs to the family of wireless network protocols whose main function is to provide internet access to local area networking allowing nearby devices to trade or exchange data using some addresses. These addresses that facilitate the wifi to locate or identify a device on the internet or local network are called aP addresses. IP stands for Internet Protocol which classifies or states the rules defining the format of data sent via wifi through the network.

As we know that WIFI is now a day’s one of the basic necessity of modern life and is easily available in almost each and every house, but we don’t know how do these devices connect.

HOW DO WE CONNECT DEVICES TO WIFI?

Almost everyone, including small children, knows that to log in or connect to wifi, we need to open the wifi portal and search for the particular or desired wifi to connect or hop over to this site. Once we find the WIFI, click on it and enter the password set by the owner. Once the password authentication is confirmed, it assigns the device a specific IP address which serves as a unique identifier for the device to be connected to the local network. These IP address can be assigned in two ways either statically in which the IP address is assigned once the device came in connection with the internet, or it can be assigned dynamically by using Dynamic Host Configuration Protocol (DHCP).

HOW TO RESERVE IP ADDRESS FO A DEVICE ON WIFI NETWORK?

Know the question that arises is that how a person can reserve I{ addresses for a device on WIFI network, well the answer is quite simple and is mentioned in the most precise way in the list below;

  1.     Disconnect the Device from the WIFI before reserving an IP address
  2.     Click on the wifi
  3.     Go to settings
  4.     Click on advanced networking
  5.     Click on ‘Add IP reservation’ In DHCP IP reservation
  6.     Click on the device which requires a static IP address
  7.     Enter a suitable IP address
  8.     Click on save
  9.     Once reconnect to the WIFI, reservations will be made

WHY IS STATIC IP ADDRESS REQUIRED?

The main reason for an IP address to b static is to set up port forwarding to that device as rebooting; we don’t want the DHCP to assign a different IP address to the device different from what we have assigned. This means that if we assign our device a state IP address, the computer won’t be assigned another IP address to it once it is rebooted, making it possible for us to set or implement port forwarding. As the IP address varies a lot and can vary from router to router, port forwarding allows it to connect with the outside world.

WHY IS PORT FORWARDING DANGEROUS?

Port forwarding can be dangerous and can b a threat for the device’s owner as port forwarding works with opening and closing of port, and opening of a port can provide direct access to hackers to hack one’s device. Another risk is when ports are open, the device can be in danger of malware threats and virus attack. The best practice while port forwarding is to use a VPN or Virtual Private Network to reduce the risk, as mentioned earlier, to one’s devices.

WHY IS IP ADDRESS NECESSARY TO CONNECT DEVICE TO WIFI?

 The concept is very similar to the mailing system as delivery of mails requires addresses to deliver mails; similarly, the internet-connected devices needs an IP address to communicate with one other. When a device sends a message to another device, it must specify the recipient’s IP address and also include its IP address so that the second device can reply. As we know, an IP address locates the device in a local area network, which helps the server locate where the message or data should be shared to perform a successful transaction in which both the sender and receiver s satisfied with the medium.
