What is the OUI D0:C9:01?

D0:C9:01 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to GLA ELECTRONICS PVT LTD. It covers every address from D0:C9:01:00:00:00 to D0:C9:01:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-C9-01.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:C9:01:00:00:00 that is D0:C9:01 — 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 GLA ELECTRONICS PVT LTD located?

GLA ELECTRONICS PVT LTD is listed at B 14/2 JHILMIL INDUSTRIAL AREA DELHI DELHI DELHI IN 110095 in the IEEE OUI registry entry for D0:C9:01. This is the address the organization registered with the IEEE, which may differ from its current operating address.
