What is the OUI 58:76:C5?

58:76:C5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to DIGI I'S LTD. It covers every address from 58:76:C5:00:00:00 to 58:76:C5:FF:FF:FF, or 16,777,216 addresses in total. It is also written 58-76-C5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:76:C5:00:00:00 that is 58:76:C5 — 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 DIGI I'S LTD located?

DIGI I'S LTD is listed at 31, Takahata, Maesawa Oshu Iwate JP 029-4204 in the IEEE OUI registry entry for 58:76:C5. This is the address the organization registered with the IEEE, which may differ from its current operating address.
