Positivo Tecnologia S.A. — 3 prefixes (MA-L)

A MAC address starting with 44:0B:AB, DC:35:F1, or 00:9E:EE belongs to Positivo Tecnologia S.A., a Brazilian electronics manufacturer, and typically identifies desktops, laptops/netbooks, tablets, smartphones, servers, or payment terminals built by the company.

All three prefixes are registered under IEEE's MA-L (24-bit OUI) class to the same organization and the same address — João Bettega, 5200, Curitiba, Paraná, Brazil 81350-000 — with no separate MA-M or MA-S registrations found in the current registry snapshot.

Positivo is a substantive, publicly traded company (B3 ticker POSI3), founded in 1989 and headquartered in Curitiba, matching the OUI registrant address. It reported roughly R$5.89 billion in 2022 revenue and around 8,600 employees, and is a market leader in Latin American educational-technology hardware and sub-BRL 2,000 laptops.

No registration date can be attributed to any of the three prefixes — IEEE's public OUI data (the IEEE MA-L registry) does not publish assignment dates, and any "date registered" shown by third-party MAC-lookup sites is a database artifact of that site, not an IEEE fact. No CVEs or vulnerability advisories specific to Positivo hardware surfaced in this research pass; that reflects the search performed, not a confirmed absence of issues.

Analyst note

three separate MA-L OUI assignments at the same registrant/address, combined with a large publicly-traded manufacturer with diverse device lines, establish this as a substantive multi-OUI vendor rather than a bare single-OUI shell.
