Which of the following are the most prominent and widely used IP protocols today?

Correct option is C

The most prominent and widely used IP protocols today are IPv4 & IPv6. IPv4 has been the primary protocol used for internet traffic for decades. However, due to the limited address space of IPv4, IPv6 was introduced, offering a much larger address pool and several technological improvements to handle modern internet demands.
Important Key Points:
1. IPv4 remains widely used, while IPv6 adoption is increasing to accommodate the growing number of devices requiring IP addresses.
2. IPv6 includes improvements in security and routing efficiency over IPv4.
Knowledge Booster:
· IPv2 & IPv3: Early versions of the Internet Protocol, not widely implemented.
· IPv5 & IPv7: IPv5 was an experimental protocol and never fully deployed, while IPv7 is a non-existent protocol.
· IPv1 & IPv7: These versions are not recognized or used in modern networking.
· IPv2 & IPv5: These versions are either early or experimental protocols that were not adopted.
