MAC address vendor

Accedian Networks — 2 prefixes (MA-L)

Primary prefix
0015AD
Block
MA-L
Status
Acquired

Summary

// what this is
Accedian Networks / Accedian Networks is registered to MAC prefix 0015AD and 1 more in the IEEE OUI database. When a device's MAC address begins with 0015AD, that block was registered by Accedian Networks / Accedian Networks — the OUI identifies the maker of the network hardware, which is not always the brand on the device. Accedian Networks / Accedian Networks was acquired; the registration remains on record with IEEE.
// analyst note
Substantive multi-OUI vendor with an identifiable product line and corporate history — clears the OUI abstain-on-shells bar. No CVEs specific to the product line were found in a light pass; treat as Unknown/not-found, not as a clean bill of health.

About this vendor.

Updated  ·  Confidence: High

A MAC address beginning 00:15:AD or 00:24:FD belongs to Accedian Networks, a Montreal-area telecom equipment maker, and typically identifies carrier-grade Ethernet demarcation hardware rather than a consumer device. Both prefixes are IEEE MA-L (24-bit OUI) blocks, each covering roughly 16.7 million addresses.

Accedian was founded in 2004 in Montreal by Patrick Ostiguy and four partners, building network interface devices that link cell towers to central offices. The company holds two OUI registrations under slightly different legal-name variants: 00:15:AD to "Accedian Networks" (4878 Levy, suite 202, St-Laurent, Quebec) and a later block, 00:24:FD, to "Accedian Networks Inc" (2351 Alfred Nobel Blvd, Saint-Laurent, QC) — consistent with a company that grew and re-registered over time.

These prefixes map to Accedian's own-brand product line: EtherNID and MetroNID (including MetroNID TE) demarcation devices used for Ethernet service delivery, SLA measurement, and timing at telecom backhaul and enterprise WAN edges, plus Accedian's Skylight software for network and application performance assurance. These are carrier/enterprise network-edge instruments, not IoT or home-network gear.

Accedian took $100M in funding from Bridge Growth Partners in 2017, acquired Performance Vision (Paris) in 2018, and was itself acquired by Cisco Systems (announced June 2023, closed September 2023); its technology now lives inside Cisco Provider Connectivity Assurance / ThousandEyes. IEEE's OUI registry publishes no assignment dates — third-party "registered" dates seen on lookup tools (2005, 2009) are database artifacts, not IEEE facts.

Security note
No CVEs specific to EtherNID/MetroNID/Skylight found in a light NVD/vendor-doc search pass; vendor docs confirm devices force a mandatory default-password change on first login

Date caveat
IEEE the IEEE MA-L registry publishes no assignment/registration date field; maclookup.app's "initial registration" dates (26 Aug 2005 for 00:15:AD; 19 Jan 2009 for 00:24:FD) are third-party database artifacts, not IEEE facts, and must not be attributed to IEEE
[Confirmed] — https://maclookup.app/macaddress/0015ad, https://maclookup.app/macaddress/0024fd
Analyst note
Two MA-L blocks under variant legal names, both in the Montreal area, a well-documented carrier-hardware product line, and a Cisco acquisition together clear the abstain-on-shells bar for verifiable company substance beyond the bare IEEE registration.
