IP Routing is the process of forwarding data packets between different networks using the Internet Protocol (IP). It involves determining the best path for data to travel from the source to the destination. Routers, which are specialized devices, play a crucial role in this process by analyzing the packet's destination address and making decisions on where to send it next. When a data packet is sent over the internet, it may pass through multiple routers before reaching its final destination. Each router uses a routing table, which contains information about various network paths, to efficiently direct the packet. This ensures that data can be transmitted quickly and reliably across interconnected networks.
