What do we need ip address?

An IP is an internet protocol address. Essentially, it is a numeric value assigned to a network device, and it is used for the identification and location of a network device. IP addresses are assigned to every type of network device.

IP addresses are the numbers that enable our computers, servers, telephones, cameras, printers and sensors to communicate with each other. Without IP addresses, we would have to copy data from device to device manually, using CDs, DVDs, hard disks or flash storage, such as a USB drive.

Why do we need an ip address ?* 

IP addresses are essential for identifying and communicating with devices connected to a network, specifically the Internet. Here are a few reasons why we need IP addresses:

1. Device Identification: IP addresses uniquely identify devices on a network. Every device connected to the Internet, such as computers, smartphones, servers, and routers, is assigned an IP address. This allows other devices to locate and communicate with them.

2. Network Routing: IP addresses are used to route data packets across networks. When you send data from one device to another over the Internet, the data is broken into smaller packets and routed based on IP addresses. Routers use IP addresses to determine the destination of the data packets and deliver them to the appropriate devices.

3. Internet Communication: IP addresses enable communication between devices over the Internet. By specifying the source and destination IP addresses, devices can send and receive data across networks, allowing for services like email, web browsing, online gaming, video streaming, and more.

4. Network Management: IP addresses play a crucial role in network management tasks. Network administrators use IP addresses to monitor and manage devices on a network, troubleshoot connectivity issues, configure network settings, and apply security measures.

5. Address Space Allocation: IP addresses are used to allocate and manage the limited pool of available addresses. There are different versions of IP addresses, such as IPv4 and IPv6, which allow for a certain number of unique addresses. IP address allocation ensures that devices on a network have a unique identifier and can access the resources they need.
