Gilbarco Veeder-Root — 3 OUI assignments (2× MA-L, 1× MA-S)

A MAC address beginning with 00:50:83, 00:21:0E, or the sub-allocated block 70:B3:D5:26:9 belongs to Gilbarco Veeder-Root, typically seen on retail fuel-station forecourt equipment: fuel dispensers, forecourt point-of-sale terminals, and automatic tank gauges.

Gilbarco Veeder-Root is a real, currently operating manufacturer headquartered in Greensboro, NC, and a subsidiary of Vontier Corporation (formerly under Danaher/Fortive). The company holds two legacy MA-L /24 blocks registered under earlier corporate-name spellings — "GILBARCO, INC." and "Gilbarco Inc." — both at the same Greensboro address, consistent with one long-lived company rather than two unrelated firms.

A third assignment, 70:B3:D5:26:9, is an MA-S /36 sub-allocation registered to "Gilbarco Veeder-Root" at an Auburn, NSW, Australia address. This block sits inside the shared IEEE MA-L base 70:B3:D5, which the IEEE Registration Authority itself holds and sub-assigns in MA-S slices to roughly 4,092 unrelated registrants. Only the specific slice 70:B3:D5:26:9/36 is Gilbarco's; the bare base 70:B3:D5 belongs to no single vendor.

Devices in this OUI family include Encore-series fuel dispensers with the Ethernet-capable PCN5 controller, Passport POS forecourt payment terminals, and Veeder-Root TLS-350/TLS4B automatic tank gauges used for fuel inventory and leak monitoring. Two dated, sourced security findings apply to the Veeder-Root ATG product line specifically: a 2015 Shodan/HD Moore survey found thousands of TLS-350/TLS-250 units exposed to unauthenticated telnet commands, and CISA advisory ICSA-25-296-03 (October 2025) documents CVE-2025-58428 and CVE-2025-55067 in the TLS4B system, both fixed in firmware 11.A. No CVE or malware/trojan association naming the Gilbarco OUI blocks themselves was found as of an August 2026 search.

Analyst note

only the sub-allocated slice 70:B3:D5:26:9/36 identifies Gilbarco Veeder-Root hardware; the shared base 70:B3:D5 must never be described as this vendor's (or any single vendor's). Security findings cited apply to the Veeder-Root ATG line specifically, not confirmed against the dispenser/POS device population under these OUIs. [Confirmed]
