IPv4 Description:
IPv4 is a standardized set of rules and conventions that govern how data packets should be formatted, addressed, transmitted, routed, and received over computer networks. It was developed in the 1980s and is the fourth version of the Internet Protocol.

Basic Use:

  1. Addressing: IPv4 uses a 32-bit address format, typically expressed as four decimal numbers separated by periods (e.g., These addresses uniquely identify devices on a network and are crucial for data routing.
  2. Data Packet Format: IPv4 divides data into packets, each with a header containing source and destination IP addresses. This allows data to be transmitted in manageable chunks.
  3. Routing: Routers use IPv4 addresses to determine the best path for data packets to reach their destination across interconnected networks.
  4. Internet Communication: IPv4 is the backbone of the global internet, enabling devices worldwide to communicate with each other. It facilitates services like web browsing, email, streaming, and online gaming.
  5. Local Networks: IPv4 is commonly used within local networks, such as home and office networks, to enable devices to communicate and access shared resources like printers and file servers.
  6. NAT (Network Address Translation): Due to the limited availability of IPv4 addresses, NAT is used to allow multiple devices within a local network to share a single public IPv4 address.
  7. Legacy Protocol: While IPv6 has been introduced to address the IPv4 address exhaustion issue, IPv4 remains widely used and is in transition alongside IPv6.

It’s important to note that the availability of IPv4 addresses has become scarce due to the growing number of internet-connected devices. As a result, the adoption of IPv6 is increasing to accommodate the expanding internet ecosystem.
