Riverbed Technology, Inc. — 3 prefixes (MA-L)

A MAC address beginning with 00:0E:B6, 00:25:50, or 6C:98:EB belongs to Riverbed Technology, Inc., typically seen on SteelHead WAN-optimization and network-acceleration appliances rather than end-user devices.

Riverbed was founded in May 2002 as "NBT Technology," rebranded Riverbed Technology in 2003, shipped its first SteelHead product in April 2004, and IPO'd on NASDAQ in September 2006. Ownership changed hands through several private-equity deals: Thoma Bravo (2015, $3.6B), a recapitalization by Apollo Global Management (December 2021), and acquisition by Vector Capital (July 2023).

The IEEE registry lists three separate MA-L (24-bit OUI) assignments for the company, all sharing the same San Francisco registry address. Three independent blocks spread over roughly a decade is the typical signature of an active hardware vendor scaling production, not a one-off shell registration, and it lines up with Riverbed's documented, long-running SteelHead product line.

Third-party MAC-vendor databases display "registration dates" for these three OUIs, but IEEE's own public OUI data does not publish assignment or registration dates at all — those third-party dates are database artifacts, not IEEE-sourced facts, and are not recorded here as such.

Registration dates

Unknown per IEEE — IEEE's public OUI data does not publish assignment/registration dates. Third-party sites show dates (maclookup.app: 00:0E:B6=2004-02-12, 00:25:50=2009-02-28, 6C:98:EB=2013-09-12) that are database artifacts, not IEEE facts

Analyst note

Three separate OUI assignments spanning roughly 2004–2013 (per third-party dating) plus a well-documented hardware product line and verifiable corporate history indicate a substantive, identifiable vendor — not a bare single-OUI shell registration
