Name a common IP address version used in networking.

The choice of IPv4 as a common IP address version in networking is indeed accurate due to its widespread use since the early days of the internet. IPv4, or Internet Protocol Version 4, provides a numerical addressing scheme and is the most commonly used protocol for assigning addresses to devices on a network. It is based on a 32-bit address scheme, which allows for approximately 4.3 billion unique addresses. This has historically been sufficient for the growth of the internet, although it has reached its limits, which is why there is a gradual transition to IPv6.

IPv5 and IPv3 are not recognized in the same way as IPv4 and IPv6. IPv5 was an experimental version primarily used for streaming audio and video, and mainly never saw a widespread application within the traditional IP networking. IPv3 was never a finished protocol and did not get adequate adoption or standardization. Therefore, when considering the primary versions of IP in use today, IPv4 stands out as the correct answer.
