IP4, or Internet Protocol version 4, is a protocol used for transmitting data over the internet. It is the fourth version of the Internet Protocol and is currently the most widely used version of the protocol.
How IP4 works
IP4 works by dividing data into smaller units called “packets” and sending these packets to their destination over the internet. Each packet contains both a destination address and a source address, which allows the packets to be routed to the correct destination.
Each device on the internet is assigned a unique IP4 address, which is used to identify the device and determine where the packets should be sent. This address is a numerical label consisting of four octets, or 8-bit numbers, separated by periods. For example, the IP4 address “192.168.1.1” consists of the four octets 192, 168, 1, and 1.
The IP4 protocol also includes a system for fragmenting and reassembling packets, called the Internet Protocol Datagram (IPD). This system allows large packets to be broken down into smaller packets for transmission and then reassembled at the destination.
Benefits of IP4
One of the main benefits of IP4 is its widespread adoption. It is the most widely used version of the Internet Protocol, and nearly all devices on the internet are able to communicate using IP4. This makes it easy for devices to communicate with each other, regardless of their location or type.
Another benefit of IP4 is its simplicity. The protocol is relatively simple and easy to understand, which has contributed to its widespread adoption. It is also relatively efficient, making it well-suited for transmitting data over the internet.
Limitations of IP4
One of the main limitations of IP4 is its limited address space. The protocol uses 32-bit addresses, which allows for a maximum of about 4.3 billion unique addresses. This may seem like a large number, but with the proliferation of devices connected to the internet, the available address space has become increasingly scarce.
To address this issue, a new version of the Internet Protocol, called IP6, was developed. IP6 uses 128-bit addresses, which allows for a much larger address space and addresses the issue of address scarcity. However, IP6 has not yet achieved widespread adoption, and many devices still use IP4.
IP4 is a widely used protocol for transmitting data over the internet. It is simple, efficient, and widely supported, but has a limited address space. While a newer version of the protocol, IP6, has been developed to address this issue, many devices still use IP4.
