Reserved for future use · RFC 1112

Class E block reserved by the IETF for future use. Not currently routable on the public internet and not in general operational use.

This range is reserved by IANA — it is not allocated to an organization, ISP, or regional internet registry. Addresses here appear on every private/internal network that follows the standard, so lookups will not identify a specific owner. 254.0.0.0/8 is a sub-block of 240.0.0.0/4, the defining reserved range.
