Which company owns MAC address prefix BC:07:1D?

MAC address prefix BC:07:1D is registered to TP-Link Systems Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:07:1D has a network interface built by TP-Link Systems Inc..

What is the OUI BC:07:1D?

BC:07:1D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TP-Link Systems Inc.. It covers every address from BC:07:1D:00:00:00 to BC:07:1D:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-07-1D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:07:1D:00:00:00 that is BC:07:1D — 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 TP-Link Systems Inc. located?

TP-Link Systems Inc. is listed at 10 Mauchly Irvine CA US 92618 in the IEEE OUI registry entry for BC:07:1D. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does TP-Link Systems Inc. own?

TP-Link Systems Inc. holds 43 OUI prefixes in the IEEE registry, of which BC:07:1D is one. A device made by TP-Link Systems Inc. could carry a MAC address from any of them.
