Which company owns MAC address prefix 24:62:78?

MAC address prefix 24:62:78 is registered to sysmocom - s.f.m.c. GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:62:78 has a network interface built by sysmocom - s.f.m.c. GmbH.

What is the OUI 24:62:78?

24:62:78 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to sysmocom - s.f.m.c. GmbH. It covers every address from 24:62:78:00:00:00 to 24:62:78:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-62-78.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:62:78:00:00:00 that is 24:62:78 — 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 sysmocom - s.f.m.c. GmbH located?

sysmocom - s.f.m.c. GmbH is listed at Siemensstr. 26a Berlin DE 10551 in the IEEE OUI registry entry for 24:62:78. This is the address the organization registered with the IEEE, which may differ from its current operating address.
