Which company owns MAC address prefix 74:93:A4?

MAC address prefix 74:93:A4 is registered to Zebra Technologies Corp. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 74:93:A4 has a network interface built by Zebra Technologies Corp..

What is the OUI 74:93:A4?

74:93:A4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Zebra Technologies Corp.. It covers every address from 74:93:A4:00:00:00 to 74:93:A4:FF:FF:FF, or 16,777,216 addresses in total. It is also written 74-93-A4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:93:A4:00:00:00 that is 74:93:A4 — 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 Zebra Technologies Corp. located?

Zebra Technologies Corp. is listed at 20314 Seneca Meadows Parkway Germantown Maryland US 21771 in the IEEE OUI registry entry for 74:93:A4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
