Set the correct default gateway

How to fill in the default gateway

Network communication has become an essential part of our daily life, and for any device connected to the network, the default gateway is particularly important. So, what is the default gateway? How should I fill it out? This article will answer these questions for you in detail.

First, we need to understand what a default gateway is. The default gateway, also known as the gateway address, is used within the LAN to connect to the external network. Simply put, it is the last address that the data packet passes through when it is sent to the target host. When we want to access the external network or communicate with other network devices, we must configure the correct default gateway. If the default gateway is not filled in correctly, the device will not be able to communicate with external networks.

So, how to fill in the default gateway? The following are operation methods for some common devices:

1. Windows operating system:
   a. Click the "Start" menu and select "Control Panel".
   b. In the Control Panel, find and click "Network and Internet".

It should be noted that different devices and operating systems may have slight differences, so please find the corresponding setting method to fill in according to the device and operating system you are using.

When filling in the default gateway, be sure to make sure that the entered address is correct. The address of the default gateway is usually provided by the network administrator or Internet service provider. If you don't know the address of the default gateway, you can ask your network administrator or refer to the relevant documentation.

To summarize, filling in the default gateway is an important step to ensure that we can communicate with the external network smoothly. Correctly filling in the default gateway can ensure that our devices can access the Internet normally and enjoy the convenience brought by the network. Hope this article helps you!
