Which company owns MAC address prefix 08:00:48?

MAC address prefix 08:00:48 is registered to EUROTHERM GAUGING SYSTEMS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:00:48 has a network interface built by EUROTHERM GAUGING SYSTEMS.

What is the OUI 08:00:48?

08:00:48 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to EUROTHERM GAUGING SYSTEMS. It covers every address from 08:00:48:00:00:00 to 08:00:48:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-00-48.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:00:48:00:00:00 that is 08:00:48 — 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 EUROTHERM GAUGING SYSTEMS located?

EUROTHERM GAUGING SYSTEMS is listed at 900 MIDDLESEX TURNPIKE, BDG. 6 BILLERICA MA US 01821 in the IEEE OUI registry entry for 08:00:48. This is the address the organization registered with the IEEE, which may differ from its current operating address.
