FAQ
- Which company owns MAC address prefix FC:E3:3D?
- MAC address prefix FC:E3:3D is registered to CLOUD NETWORK TECHNOLOGY SINGAPORE PTE. LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with FC:E3:3D has a network interface built by CLOUD NETWORK TECHNOLOGY SINGAPORE PTE. LTD..
- What is the OUI FC:E3:3D?
- FC:E3:3D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to CLOUD NETWORK TECHNOLOGY SINGAPORE PTE. LTD.. It covers every address from FC:E3:3D:00:00:00 to FC:E3:3D:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-E3-3D.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in FC:E3:3D:00:00:00 that is FC:E3:3D — 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.
