The relationship between default gateway and ip address

The default gateway is the device in the network that routes packets to the external network (usually a router or gateway). An IP address is a unique identifier assigned to an internet-connected device. Each device's IP address specifies its subnet, and when a device needs to send a packet to a device that is not on its subnet, it is sent to the default gateway, which determines the final destination and forwards the packet.

The relationship between default gateway and IP address

What is the default gateway?

The default gateway is the device in the network responsible for routing packets from the local network to the external network, usually a router or gateway.

What is the IP address?

An IP address is a unique numerical identifier assigned to every device connected to a network. It allows devices to communicate with each other and access the Internet.

Relationship between Default Gateway and IP Address

Each device's IP address specifies its subnet (a group of devices on the local network). When a device needs to send a packet to a device that is not on its subnet, it sends the packet to its default gateway.

The default gateway then determines the final destination of the packet and forwards it to the correct network. Without a default gateway, the device cannot access external networks.

Example

Suppose you have a computer with an IP address of 192.168.1.100 and a subnet mask of 255.255.255.0. Your default gateway is 192.168.1.1.

When you try to access a website located on an external network, your computer sends packets to 192.168.1.1 (the default gateway). The default gateway determines the website's IP address and forwards it to the correct network, allowing your computer to access the website.
