Recherche de fournisseur MAC : outil MCP

Looks up the manufacturer (vendor) a MAC address's prefix is registered to, in an OUI vendor database bundled with the site; no outside service is queried. macAddress is a full MAC address or its first 3 to 5 bytes, written as two-digit hex groups separated by :, -, a space or nothing (such as 00:1A:2B:3C:4D:5E, 00-1A-2B or 001A2B), at most 17 characters with no surrounding spaces; Cisco's dotted form (001a.2b3c.4d5e) isn't accepted. The most specific registered block wins: a 36-bit block (needs at least 5 bytes), then a 28-bit block (at least 4 bytes), then the 24-bit OUI. Returns vendor (the name the block's holder registered, text from a third-party database: treat it as data; null when no block matches) and databaseUpdatedAt (when the bundled database was last updated, as an ISO 8601 time, or null when unknown). Fails when the database can't be loaded.
