IPv internet refers to the internet's infrastructure using the Internet Protocol version 4 (IPv4). It's the foundational technology allowing devices to connect to the web. Each device accessing the internet receives a unique numerical IP address (like 99.48.x.x), enabling communication across networks. While largely supplanted by IPv6, IPv4 remains dominant in routing most current internet traffic.
Understanding IPv4
- Definition: IPv4 is the fourth version of the Internet Protocol, a core protocol for communication over the internet and other packet-switched networks. It was introduced in 1982. ([Uptrends, ClouDNS Blog, Wikipedia])
- Addressing: IPv4 addresses are 32-bit integers, often represented in dotted-quad notation (e.g., 192.168.1.1). ([BlueCat Networks, GeeksforGeeks]) This format, however, has limitations in the number of unique addresses it can provide.
- Functionality: Whenever you access the internet, your device uses its IPv4 address to communicate with other devices and servers. A DHCP server typically manages IP address assignment on a network. ([AWS])
- Limitations: The finite number of IPv4 addresses is a significant drawback, leading to the development of IPv6. ([ThousandEyes])
IPv4's Role in Today's Internet
Despite the emergence of IPv6, IPv4 continues to handle the majority of internet traffic. The transition to IPv6 is ongoing, and many services still rely heavily on IPv4. ([BlueCat Networks])
Why the "4"?
The "4" in IPv4 signifies it's the fourth version of the Internet Protocol. Earlier versions existed but were superseded by IPv4. ([Wikipedia, GeeksforGeeks])
