Which company owns MAC address prefix 38:0A:4F?

MAC address prefix 38:0A:4F is registered to PRACHI ENTERPRISES in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 38:0A:4F has a network interface built by PRACHI ENTERPRISES.

What is the OUI 38:0A:4F?

38:0A:4F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PRACHI ENTERPRISES. It covers every address from 38:0A:4F:00:00:00 to 38:0A:4F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 38-0A-4F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 38:0A:4F:00:00:00 that is 38:0A:4F — 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 PRACHI ENTERPRISES located?

PRACHI ENTERPRISES is listed at B-141, 2nd FLOOR SECTOR-6 NOIDA NOIDA UTTARPRADESH IN 201301 in the IEEE OUI registry entry for 38:0A:4F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
