This IP address is trying to connect to the internet. It helps users to communicate with other devices on the Internet.

This network protocol enables servers to automatically assign an IP address to your computer or PC for a unique network.

Ethernet vs Wi-Fi: Benefits: 

Nowadays, Wi-Fi is the most common type of network connection. whereas Ethernet has been since the 1970s. Ethernet requires wired connection. However, Wi-Fi does not require any cable to get connected. I have shared some vital benefits of Ethernet over Wi-Fi connections. 

Flexibility and Security: 

You might be dealing with wires, you’ve got the flexibility to transfer data up to 100 meters, that’s 328 feet from your modem or router with Ethernet cables wires. Since most of the routers already feature Ethernet ports, it doesn’t take much to make the switch at home or even to hard-wire your game console or desktop gaming while your phone and tablet are connected to your Wi-Fi network. 

For more business-orientation. The control and security performed by Ethernet are hard to beat. With a physical network, you keep control of who’s connected to your local network at any given time. This frees up data for your users and helps to avoid unwanted (Harmful and costly) security breaches. 

Signal Stability:  

Connecting to a wired LAN is more costly and time-consuming than a Wireless Local Area Network. It has certain perks. First, Wi-Fi signals are transmitted through radio frequencies. Like sometimes you’ve passed through a subway while listening to your car radio because the radio waves are prone to interference and same as Wi-Fi. On the other hand, wired Ethernet networks are not limited to interference. 

Without interference, your Internet is less likely to struggle with any slowdowns or disconnections. However, when you’re transferring massive data media files to other devices. Similarly, your own walls won’t cause issues for Ethernet, and because each device is hardwired, you don’t have to divide your bandwidth between your laptop and PS4.
