Which company owns MAC address prefix CC:E7:98?

MAC address prefix CC:E7:98 is registered to My Social Stuff in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:E7:98 has a network interface built by My Social Stuff.

What is the OUI CC:E7:98?

CC:E7:98 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to My Social Stuff. It covers every address from CC:E7:98:00:00:00 to CC:E7:98:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-E7-98.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:E7:98:00:00:00 that is CC:E7:98 — 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 My Social Stuff located?

My Social Stuff is listed at Sint-Hubertussyraat 65 Berchem BE 2600 in the IEEE OUI registry entry for CC:E7:98. This is the address the organization registered with the IEEE, which may differ from its current operating address.
