Absolute Analysis — 24:BB:C1 (MA-L)

The 24:BB:C1 prefix is a single MA-L block registered to Absolute Analysis, a test-and-measurement instrument company headquartered at 2393 Teller Road, Suite 109, Newbury Park, California. Founded in 1991 and operating with roughly 11–50 employees, Absolute Analysis built professional protocol analyzers, traffic generators, bit-error-rate testers, and RF-over-CPRI spectrum instruments — its Investigator analyzer platform and Integris 3000/2000 RF testers served telecom radio-access-network, datacom, storage, and aerospace/defense labs (supporting CPRI/OBSAI, Ethernet/FCoE, Fibre Channel, SAS/SATA, Serial RapidIO, and AFDX). A 24:BB:C1 address therefore most plausibly belongs to a professional lab/enterprise test appliance, not consumer networking gear; no switches, access points, or routers are corroborated on this prefix. The company no longer operates independently: EXFO (a Quebec test-and-measurement firm) acquired the majority of its optical and RF-over-CPRI assets on October 31, 2016 for approximately US$8.25 million, and absoluteanalysis.com now 301-redirects to EXFO's acquisitions landing page. Two data traps apply. First, the "October 7, 2011" date shown on third-party MAC-lookup sites is a database artifact — IEEE publishes no OUI assignment date, so allocated_date stays null. Second, the CVEs listed under "Absolute" on CVEDetails belong to Absolute Software, a separate endpoint-security company, and are not attributable to this vendor.

Analyst note

a 24:BB:C1 address most plausibly identifies a professional test/measurement appliance built by Absolute Analysis for telecom/datacom lab use — not a consumer router, AP, or switch. Do not record any "October 2011" date as an IEEE registration date (third-party artifact). The Absolute CVEs on CVEDetails are Absolute Software's, not this vendor's.
