Lookup MAC/EUI48 OUI vendor name information from the Wireshark manufacturer database.
This library allows you to provide a MAC/EUI48 address and returns information on the vendor registered to the Organizationally Unique Identifier (OUI) component of the supplied address. For each entry in the Wireshark database, this will be at a minimum the vendor's Wireshark short name, but most entries include the full organization/company name and some also include a descriptive comment.
Where IEEE Registration Authority blocks have been sub-divided, the specific manufacturer is returned. Note that a vendor/organization may have been allocated multiple blocks by the IEEE - these are each treated independently, should a vendor sub-division be later re-allocated or renamed following acquisition.
Example wget command to download the manufacturer database:
wget -O manuf.txt 'https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob_plain;f=manuf'
