Thus the default gateway will act as an access point to the other networks when one network wants to communicate or send data packets to another network. This also includes the alteration of IP addressing and subnet mask of the system and network topologies.

If the IP packet at some instance of the node doesn’t find the suitable set of rules and route to be followed to deliver the packet to the destination address, then it will choose the default gateway for the further routing process.
