If The Default Gateway Is Configured Incorrectly On The Host, What Is The Impact On Communications?

Default gateway

A default gateway act as a gate between the devices that want to communicate with each other. When the message is transferred to the destination first the request went toward the default gateway and then it will move toward the Local network (LAN). The default gateway is an intermediate device between the network and the local area network.

In an easy way when the devices want a transmission other than their network, they need a default gateway. The devices which are used as a default gateway are the routers or switches (multiple switches). It is a node in a network that uses the protocol which acts as the host for another network in a case when no route is the same as the destination IP address of the packet.

The main purpose of the default gateway is to allow access to the requested web pages cause the request is sent toward the gateway before the internet. The gateway is the intermediate device and the key other than the original is used for the device’s connection on one subnet. The gateway ensures the packet transmission to its destination even the source and the destination used other protocols.

When the message or packet transfer the request will reach the routing table to find the most suitable and efficient path and the destined router, the gateway also receive the request who has no destined router and ensure the flow of the request as well.

How to find the default gateway?

The process is to find the default gateway in the windows computer while in the MAC book it is different. Now let’s start with the procedure:

• In the window search for the command prompt for that tap on the search bar and type the CMD and double tap on it. If you can’t be able to find the command prompt with this method then press the window key by pressing the R key along with it. The run menu came up with this process than type the CMD and click OK.
• In the black window which is the CMD window type ipconfig and then TAP on the ENTER button and the information related to the network will display.
• Scroll down you can find the default gateway along with the IP address.
• Once the gateway is found then on the web browser paste the IP address on the search bar and click on ENTER.
• A box will display demanding the router username and password.it will also show on the router.

If the default gateway is configured incorrectly on the host, what is the impact on communications?

• The host can’t communicate with the local network.
• Communication is not affected.
• The host can be able to communicate with others on the local network but can’t communicate with others on the remote network.
• The host can transmit with the remote but cannot communicate with the local network with another host.
• A ping of 127.0.0.1 will never succeed.

Answer: the host will be able to transmission with another host on the local network but cannot communicate on the remote network because to communicate outside the network the default gateway is necessary and if it is configured incorrectly the impact or transmission will never happen.
