What Is a Default Gateway in Networking?

You can’t live without the internet

A default gateway allows devices on one network to communicate with devices on another network. For example, when a computer requests a web page, the request goes through the default gateway before leaving the local area network (LAN) to reach the Internet.

Think of the default gateway as an intermediary between your local network and the Internet. The default gateway transmits internal data to the Internet and vice versa.

In most homes and small offices, the default gateway is the router that routes local network traffic to the cable or DSL modem, which then forwards it to the Internet Service Provider (ISP).

How traffic goes through the default gateway

All clients on the network point to a default gateway that redirects their traffic. The default gateway device passes this traffic from the local subnet to devices on other subnets.The default gateway connects the local area network to the Internet, although the internal gateway used for internal communication Local area networks are used for corporate networks.

For example, a default gateway in a home network understands the specific routes to take to move Internet requests from one computer outside the network to the next computer that can understand what needs to be done. From there, the same process happens until the data reaches its destination.

the word Lack In this term, it means that it is the default device to look for when sending information over the network.

For each network that traffic enters, the network’s default gateway sends the information to the Internet and back to the requesting computer.

The default gateway is used to understand the request when the traffic is destined for other internal devices rather than devices outside the local network, but instead of sending the data outside the network, it routes it to the appropriate local device.

This process is understood in terms of the IP address requested by the source device.

Default gateway type

There are generally two types of default internet gateways:

  • In a home or small business network that uses a broadband router to share an Internet connection, the home router acts as the default gateway.
  • In a home or small business network without a router, such as a home with dial-up Internet access, the router at the ISP’s location is used as the default gateway.

You can also use a computer instead of a router to configure the default network gateway. These gateways use two network adapters: one connected to the local subnet and the other connected to the remote network.

A router or gateway computer can be used to connect local subnets, such as those in large companies.

How to Find the IP Address of the Default Gateway

If you have network problems or make changes to your router, you need to know the IP address of the default gateway.

  • In Microsoft Windows, the computer’s default gateway IP address can be accessed from the command prompt using the “ipconfig” command, or the computer’s default gateway IP address can be accessed through the control panel.
  • On macOS and Linux, the “netstat” and “ip route” commands are used to find the default gateway address.

Frequently Asked Questions

  • How do I find the default gateway on a Mac?

    Open Terminal app on Mac Command+Spacebar Find shortcuts to Spotlight.Once a new terminal window opens, type netstat -nr | grep default† You can also find the default gateway at: System Preferencesnetworkadvanced TCP/IProuter

  • How to change the default gateway in Windows 10?

    To change the default gateway IP address for your home network, log into the router from a web browser with administrator credentials. Depending on your model, you will find the default gateway setting in settings or connections. Edit the default gateway IP address as needed and save the changes.

What Is a Default Gateway in Networking?

You can’t get to the internet without one

A default gateway makes it possible for devices in one network to communicate with devices in another network. If a computer, for example, requests a web page, the request goes through the default gateway before exiting the local network (LAN) to reach the internet.

Think of a default gateway as an intermediate device between the local network and the internet. The default gateway transfers internal data to the internet and back again.

In most homes and small offices, the default gateway is a router that directs traffic from the local network to the cable or DSL modem, which sends it to the internet service provider (ISP).

All the clients on a network point to a default gateway that routes their traffic. The default gateway device passes this traffic from the local subnet to devices on other subnets. The default gateway connects a local network to the internet, although internal gateways for communication within a local network are used in corporate networks.

The default gateway in a home network, for example, understands specific routes that must be taken to move internet requests from a computer out of the network and onto the next piece of equipment that can understand what needs to be done. From there, the same process happens until the data reaches its destination.

The word default in this term means that it’s the default device that’s looked for when information needs to be sent through the network.

With each network that the traffic arrives at, that network’s default gateway relays the information to the internet and back to the computer, which requested it.

When traffic is bound for other internal devices and not a device external to the local network, the default gateway is used to understand the request, but instead of sending the data out of the network, it points it to the correct local device.

This process is understood based on the IP address that the originating device requests.

Types of Default Gateways

Internet default gateways are typically one of two types:

In home or small business networks with a broadband router to share the internet connection, the home router serves as the default gateway.
In home or small business networks without a router, such as for residences with dial-up internet access, a router at the internet service provider location serves as the default gateway.

Default network gateways can also be configured using a computer instead of a router. These gateways use two network adapters: one is connected to the local subnet and the other is connected to the outside network.

Either routers or gateway computers can be used to network local subnets such as those in large businesses.

How to Find Your Default Gateway IP Address

You’ll need to know the IP address of the default gateway if there’s a network problem or to make changes to the router.

In Microsoft Windows, the IP address of a computer’s default gateway can be accessed through Command Prompt with the “ipconfig” command, as well as through the Control Panel.
In macOS and Linux, the “netstat” and “ip route” commands are used to find the default gateway address.
FAQ

How do I find the default gateway on a Mac?
Open the Terminal app on a Mac by using the Command+Spacebar shortcut to search Spotlight. Once a new Terminal window opens, enter netstat -nr | grep default. You can also find the default gateway from System Preferences > Network > Advanced > TCP/IP > Router.

How do I change the default gateway in Windows 10?
If you’d like to change the IP address of your home network’s default gateway, log in to your router from a web browser with the admin credentials. Depending on your model, you might find the default gateway settings from the setup or connections areas. Edit the default gateway IP address as you please and save your changes.
