Which company owns MAC address prefix 00:12:AE?

MAC address prefix 00:12:AE is registered to HLS HARD-LINE Solutions Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:12:AE has a network interface built by HLS HARD-LINE Solutions Inc..

What is the OUI 00:12:AE?

00:12:AE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to HLS HARD-LINE Solutions Inc.. It covers every address from 00:12:AE:00:00:00 to 00:12:AE:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-12-AE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:12:AE:00:00:00 that is 00:12:AE — 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 HLS HARD-LINE Solutions Inc. located?

HLS HARD-LINE Solutions Inc. is listed at 53 Main Street Dowling Ontario CA P0M 1R0 in the IEEE OUI registry entry for 00:12:AE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
