Which company owns MAC address prefix 00:0E:CE?

MAC address prefix 00:0E:CE is registered to S.I.T.T.I. S.p.A. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:0E:CE has a network interface built by S.I.T.T.I. S.p.A..

What is the OUI 00:0E:CE?

00:0E:CE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to S.I.T.T.I. S.p.A.. It covers every address from 00:0E:CE:00:00:00 to 00:0E:CE:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-0E-CE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:0E:CE:00:00:00 that is 00:0E:CE — 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 S.I.T.T.I. S.p.A. located?

S.I.T.T.I. S.p.A. is listed at Via Cadorna 69 Vimodrone Milan IT I-20090 in the IEEE OUI registry entry for 00:0E:CE. This is the address the organization registered with the IEEE, which may differ from its current operating address.

S.I.T.T.I. S.p.A.

MAC address prefix 00:0E:CE is registered to S.I.T.T.I. S.p.A. in the IEEE OUI registry. Any device whose MAC address begins with 00:0E:CE has a network interface built by S.I.T.T.I. 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 00:0E:CE:00:00:00 to 00:0E:CE:FF:FF:FF.
