MAC address vendor

Symantec Corporation — 3 prefixes (MA-L)

Primary prefix
00:0D:D4
Block
MA-L

Summary

// what this is
Symantec is registered to MAC prefix 00:0D:D4 and 2 more in the IEEE OUI database. When a device's MAC address begins with 00:0D:D4, that block was registered by Symantec — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A MAC on 00:0D:D4, 00:A0:65, or B4:A9:84 identifies genuine Symantec-registered hardware, most plausibly one of the ProxySG / Advanced Secure Gateway appliance lines now owned by Broadcom — not the Norton consumer software brand, which is now under Gen Digital and unrelated to these OUIs. The similarly-named 00:22:A1 is a separate registrant and must not be attributed to Symantec Corporation.

About this vendor.

A MAC address starting with 00:0D:D4, 00:A0:65, or B4:A9:84 belongs to Symantec Corporation, and on a live network most plausibly identifies one of the company's own security appliances — a ProxySG web proxy, an Advanced Secure Gateway, or a Symantec Management Center box — rather than an ordinary computer that merely runs Norton or Symantec software.

These three blocks are the only IEEE MA-L (24-bit) assignments registered directly to "Symantec Corporation"; a registry cross-check turned up no MA-M or MA-S block under that exact name. Each carries a different registered address — Waltham, MA; Cupertino, CA; and Mountain View, CA — reflecting different eras of the company rather than one fixed headquarters.

Symantec Corporation was founded in 1982 and traded on NASDAQ as SYMC. In November 2019 it sold its enterprise security business — including the appliance lines these OUIs most plausibly tag — to Broadcom Inc. for $10.7 billion. The same day, the remaining consumer entity renamed itself NortonLifeLock, which later merged with Avast and became Gen Digital Inc. in 2022.

A fourth, similarly-named prefix, 00:22:A1, belongs to a different registrant — "Huawei Symantec Technologies Co.,Ltd." — a 2008-2012 joint venture that Huawei fully bought out in 2012. It is not part of this vendor's prefix set and should not be attributed to Symantec Corporation.

Named, dated CVEs exist against the ProxySG and Advanced Secure Gateway product lines these OUIs likely tag, including an unrestricted file-upload flaw (CVE-2016-10258) and a management-console reflected XSS patched before version 6.5.10.6/6.7.2.1. Most date to 2016-2018 and have since been patched; none indicate the appliances or brand are associated with malware distribution.

Special note
IEEE's MA-L registry schema carries no date field for any of the 4 prefixes discussed (the 3 Symantec blocks plus the separate Huawei Symantec block); maclookup.app shows vendor-level "First Seen"/"Last Mod" scrape timestamps, which are third-party database artifacts, not IEEE facts, and must not be read as a registration date
