The class E IPv4 address range, which spans from 240.0.0.0 to 255.255.255.255, is primarily designated for experimental or research purposes. This classification means that the addresses in this range are not intended for general public use but rather for testing new protocols, experimentation, and research by industry and academic institutions.

This reservation allows for innovation and testing of new networking concepts that could potentially be developed further or standardized, without interfering with the regular operation of public or private networks. As a result, anyone engaged in network research can utilize these addresses for their projects, thus fostering advancements in networking technology.
