What is the OUI D4:53:47?

D4:53:47 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Merytronic 2012, S.L.. It covers every address from D4:53:47:00:00:00 to D4:53:47:FF:FF:FF, or 16,777,216 addresses in total. It is also written D4-53-47.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D4:53:47:00:00:00 that is D4:53:47 — 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 Merytronic 2012, S.L. located?

Merytronic 2012, S.L. is listed at Parque empresarial Boroa Parcela 2C-1 Amorebieta Bizkaia ES 48340 in the IEEE OUI registry entry for D4:53:47. This is the address the organization registered with the IEEE, which may differ from its current operating address.
