Memotec, Inc. — 2 prefixes (MA-L)

A MAC address beginning with 00:20:87 or 00:40:0E belongs to Memotec, Inc., a Montreal-based data communications and telecom networking equipment maker whose IEEE MA-L registrations trace to two dedicated /24 blocks, both registered at the same Quebec address.

Memotec Communications Inc. was acquired by Kontron Embedded Computers AG of Munich in a deal completed July 1, 2001, worth up to CAD $67.6 million, and folded into a Kontron subsidiary called Kontron Communications. In 2004, Comtech Telecommunications Corp. agreed to acquire certain Memotec assets and liabilities from Kontron AG for roughly $2.6 million, and the Memotec product line now operates under Comtech EF Data, a Comtech Telecommunications Corp. subsidiary (NASDAQ: CMTL).

Hardware carrying these prefixes is WAN optimization and compression equipment: Stampede and FX Series appliances such as the FX-1010 and FX-5020C, plus access devices, edge switches, and voice-compression or cellular-backhaul gear aimed at satellite (SATCOM), ISP, and telecom-carrier links, per current Comtech EF Data documentation and reseller listings.

A confirmed vulnerability sits on the current descendant product line: CVE-2020-5179 documents an OS command-injection flaw (CWE-78, CVSSv3.1 7.2 High) in Comtech Stampede FX-1010 firmware 7.4.3, exploitable by a remote authenticated administrator through the Diagnostics Ping page's Target IP field. No CVE is recorded against the "Memotec" name itself as of an August 2026 search, and no malware or trojan association was found for the vendor or product line in that same search.

Both 00:20:87 and 00:40:0E are dedicated MA-L assignments naming MEMOTEC, INC. individually — neither sits inside a shared IEEE-administered base — so either prefix reliably identifies Memotec-lineage hardware. IEEE's MA-L registry publishes no registration date for either block, and no third-party lookup tool (Wireshark manufacturer database, maclookup.app) lists a Memotec entry to check for a database-artifact date.

Analyst note

Both blocks are dedicated MA-L assignments naming MEMOTEC, INC. individually (not a slice of a shared IEEE base), so a device presenting a MAC in either 00:20:87:xx:xx:xx or 00:40:0E:xx:xx:xx can be attributed to Memotec-lineage hardware, now sold and supported as Comtech EF Data Stampede/FX Series equipment; given CVE-2020-5179 on the current product family, any such device found in production should have firmware checked against vendor advisories and the Diagnostics Ping interface access-restricted
