What Will Happen If The Default Gateway Address Is Incorrectly Configured On A Host?

What will happen if the default gateway address is incorrectly configured on a host?

• In LAN the host can’t communicate with each other.
• The packets which are coming from the host cannot be forwarded by the switch.
• For the accurate default gateway, the host needs to use the ARP.
• To another network, the host cannot communicate with the other.
• Ping to 127.0.0.1 from the host is not successful.

Answer: when the message is sent to the other network from the host it can be directly sent with the help of the message but to send the message to the remote network, we need the router for the successful conversation which is also called a default gateway. Because the frames of the remote network can not be used with a direct message and the IP frames are sent to the router in the remote network then the router will further be sent toward the destination port. That’s why if the default gateway address is incorrectly configured on the host it can’t be able to communicate with another host on the remote network but communicate on the same.

Now that you get your answer let’s further study the default gateway, its function, and how to find it on the PC. Read the topic to the end so that your curiosity ends!

What is the default gateway?

A default gateway in the computer network is the node that acts as the forwarding node when the IP frames cannot be able to find their destination port to another network. in simple when the host wants to communicate outside its network then the default gateway is used. the router and multilayer switch is commonly used as the default gateway.

Functions of the default gateway:

The functions are discussed in the following section:

• The main work of the gateway is to forward the packets to their destination when they cannot be able to find them in another network.
• The router or node is responsible for the connection with the host network.
• When the frames are sent then at first they come toward the default gateway and then with the help of they are forwarded toward the destinated route. The default gateway is the correct spot for the frames in the network.

How to find the PC’S default gateway?

You can find the default address of the PC with the help of the few steps in the following:

• On the command prompt type “ipconfig” and then tap on Enter.
• Different information is shown on the window scroll down and checks the default gateway which is written on the right of the IP address of the device.

If the configuration of the default gateway is not happening then the frames will be dropped because they can’t be able to leave the host without configuration.

If the configuration is incorrectly configured then a few problems might be arising:

• Communication with the host of the other network is not possible.
• The packets can not be forwarded by the switch.
• The ARP is used to find the accurate default gateway.
