A default gateway allows devices within one network to send information to devices within another network. If you are requesting a certain web page, the traffic is first sent to your default gateway before leaving the local network to reach its intended destination.
Probably the simplest way to understand a default gateway is to think of it as an intermediary or middleman between your local network and the World Wide Web. It is essential for transmitting information from the local subnet to other subnets, and vice-versa.
On most home and business networks, which are usually made up of a single router and multiple connected computers and mobile devices, the private IP address given to your router is the default gateway IP address.
This numerical address will be called “default gateway” on Windows devices, while it is normally referred to as “router” on iOS and Mac devices. When it comes to other platforms, however, it might be named something along the likes of “gateway” or “gateway route”.
Learn the steps to find your gateway IP address on Windows, Mac OS X, Android, iPhone/iPad, Linux, and Chrome OS.
Note: The steps for finding your gateway IP on Android will vary depending on the version you are currently using.
A default gateway helps two or more hosts with different IPs to communicate with each other when connected to the same router. Without a default gateway, devices connected on the same router won’t be able to communicate with each other.
If the default gateway IP address is incorrectly configured then, the devices connected on the local network will be unable to communicate outside their network. However, they can communicate with each other internally.
A broadcast address is what you use when you want all nearby devices to see your request visibly. On the other hand, a default gateway is what you use when you want a remote device to understand your request.
They can’t be the same. Each computer has a unique IP address, and that’s what distinguishes it from the rest of the devices.
