AT&T
MAC address prefix 08:00:6A is registered to AT&T in the IEEE OUI registry. Any device whose MAC address begins with 08:00:6A has a network interface built by AT&T. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from 08:00:6A:00:00:00 to 08:00:6A:FF:FF:FF.

FAQ
- Which company owns MAC address prefix 08:00:6A?
- MAC address prefix 08:00:6A is registered to AT&T in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:00:6A has a network interface built by AT&T.
- What is the OUI 08:00:6A?
- 08:00:6A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AT&T. It covers every address from 08:00:6A:00:00:00 to 08:00:6A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-00-6A.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 08:00:6A:00:00:00 that is 08:00:6A — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.
- Where is AT&T located?
- AT&T is listed at 3300 E Renner Road Richardson TX US 75082 in the IEEE OUI registry entry for 08:00:6A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does AT&T own?
- AT&T holds 5 OUI prefixes in the IEEE registry, of which 08:00:6A is one. A device made by AT&T could carry a MAC address from any of them.
