Which company owns MAC address prefix 5C:A3:EB?

MAC address prefix 5C:A3:EB is registered to SKODA DIGITAL s.r.o. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 5C:A3:EB has a network interface built by SKODA DIGITAL s.r.o..

What is the OUI 5C:A3:EB?

5C:A3:EB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SKODA DIGITAL s.r.o.. It covers every address from 5C:A3:EB:00:00:00 to 5C:A3:EB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 5C-A3-EB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 5C:A3:EB:00:00:00 that is 5C:A3:EB — 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 SKODA DIGITAL s.r.o. located?

SKODA DIGITAL s.r.o. is listed at Na Rovince 874 Ostrava Hrabova CZ 720 00 in the IEEE OUI registry entry for 5C:A3:EB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
