Which company owns MAC address prefix 00:02:63?

MAC address prefix 00:02:63 is registered to RPS S.p.A. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:02:63 has a network interface built by RPS S.p.A..

What is the OUI 00:02:63?

00:02:63 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to RPS S.p.A.. It covers every address from 00:02:63:00:00:00 to 00:02:63:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-02-63.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:02:63:00:00:00 that is 00:02:63 — 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 RPS S.p.A. located?

RPS S.p.A. is listed at Viale Europa 7 Legnago IT 37045 in the IEEE OUI registry entry for 00:02:63. This is the address the organization registered with the IEEE, which may differ from its current operating address.

RPS S.p.A.

MAC address prefix 00:02:63 is registered to RPS S.p.A. in the IEEE OUI registry. Any device whose MAC address begins with 00:02:63 has a network interface built by RPS S.p.A.. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from 00:02:63:00:00:00 to 00:02:63:FF:FF:FF.
