Renewable energy flows involve natural phenomena such as sunlight, wind, tides, plant growth, and geothermal heat, as the International Energy Agency explains: Renewable energy is derived from natural processes that are replenished constantly.
Each IP address includes a network ID and a host ID. 1  The network ID (also known as a network address) identifies the systems that are located on the same physical network bounded by IP routers. 2  The host ID (also known as a host address) identifies a workstation, server, router, or other TCP/IP host within a network.
Here's how it works: Every device on the Internet needs a unique IP address. Your ISP provides you with one, allowing one device to access the Internet. A router will access the Internet through that IP address, then provide local IP addresses--not visible on the Internet--for the PCs and other devices connected to it.
