MAC / OUI vendor directory
40,318 manufacturer prefixes from the IEEE OUI registry. Search by company or OUI.
A MAC prefix is not a permanent vendor identifier. 1,856 of these 40,319 prefixes, 4.6%, resolve to a different organisation today than they did in 2016.
Measured across 116 dated captures of the IEEE registry between 2016-07-29 and 2026-10-09. The IEEE publishes current state only and overwrites the file in place, so this record does not exist anywhere else. Read the report · download the data
