🟢lookup(mac)
Resolve a MAC address or OUI prefix to its registered organization using longest-prefix match across the MA-L, MA-M, MA-S, IAB, and CID registries. Reports the block type, address count, registration country, and a link to the full record page. Randomized and locally administered addresses usually have no registered organization.
