What is the difference between a default gateway and default route?

In other words, the default route is the destination that a packet is sent to if the router doesn’t have instructions to send it somewhere else.

Do I need a default gateway?

This is why we need a default gateway. The default gateway is used as the destination of all traffic that is not on the same subnet. The gateway is a layer 3 device such as a router or multi-layer switch that is used to route traffic on a hop-by-hop basis.

Is default gateway same as IP address?

Yes, the default gateway IS an IP address, the IP address of your router. When a computer needs to reach another that resides on a network that is different from the one it is on it needs to know where to send or ROUTE the packets. The gateway is also called the Next Hop in routing terms.
