FAQ
- Which company owns MAC address prefix F0:2B:18?
- MAC address prefix F0:2B:18 is registered to Nanjing Jiahao Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:2B:18 has a network interface built by Nanjing Jiahao Technology Co., Ltd..
- What is the OUI F0:2B:18?
- F0:2B:18 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Nanjing Jiahao Technology Co., Ltd.. It covers every address from F0:2B:18:00:00:00 to F0:2B:18:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-2B-18.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in F0:2B:18:00:00:00 that is F0:2B:18 — 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 Nanjing Jiahao Technology Co., Ltd. located?
- Nanjing Jiahao Technology Co., Ltd. is listed at Moling Industrial Park, Development Zone, Jiangning, Nanjing Nanjing Jiangsu CN 211111 in the IEEE OUI registry entry for F0:2B:18. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does Nanjing Jiahao Technology Co., Ltd. own?
- Nanjing Jiahao Technology Co., Ltd. holds 7 OUI prefixes in the IEEE registry, of which F0:2B:18 is one. A device made by Nanjing Jiahao Technology Co., Ltd. could carry a MAC address from any of them.
