    A Default Gateway is a node (router) in a computer network. A Default Gateway server as an IP A router that a network computer used to send data to a computer in another network or Internet. The Internet wouldn’t be any use to us without a gateway.

    Default gateway often connects your local network to the internet, although internal gateways for communication within a local network also serve a useful purpose in corporate networks.

    Why We Used Default Gateway?

    The source device and destination device are either on the same subnet or they're on different subnets. 

    For Example
    So now our source and destination address and subnet masks are:

    192.168.69.22 255.255.255.0
    192.168.53.17 255.255.255.0

    we are still using /24 subnet masks, we know these two devices are in different subnets since the third octet for each is different.

    Subnets are used to break up broadcasts, using the broadcast mechanism with an ARP table will not work in this situation. For Handle This type of Situations we will use the default Gateway.

    Network Administrators configure the computer routing Capability with an IP range starting address as the default gateway and points all clients to that IP address.

    The default gateway always resides in the same subnet as the end device IP. The gateway can really be any unique address within the subnet itself, but most network administrators designate the first number of the subnet as the gateway.
