FAQ
- Which company owns MAC address prefix 30:0A:C5?
- MAC address prefix 30:0A:C5 is registered to Ruio telecommunication technologies Co., Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:0A:C5 has a network interface built by Ruio telecommunication technologies Co., Limited.
- What is the OUI 30:0A:C5?
- 30:0A:C5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ruio telecommunication technologies Co., Limited. It covers every address from 30:0A:C5:00:00:00 to 30:0A:C5:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-0A-C5.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 30:0A:C5:00:00:00 that is 30:0A:C5 — 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 Ruio telecommunication technologies Co., Limited located?
- Ruio telecommunication technologies Co., Limited is listed at Room 2501, Broadegate Software Building, No,1003 Keyuan Road, Shenzhen guangdong CN 518000 in the IEEE OUI registry entry for 30:0A:C5. This is the address the organization registered with the IEEE, which may differ from its current operating address.
