One host can be attached to multiple subnets if they are capable of transmitting data from one subnet to another. Those hosts that can transmit data from one subnet to another are called routers or gateways, and these hosts are the ones that connect the subnets to the internet via an uplink address.
Hosts capable of transmitting data across multiple subnets are designated as routers or gateways. Routers play a crucial role in directing network traffic and connecting subnets to the internet using an uplink address. This address acts as a gateway, facilitating efficient data transfer between local and external networks. Essentially, routers or gateways serve as intermediaries, enhancing overall communication within the network and with external systems.
