FAQ
- Which company owns MAC address prefix 1C:A0:B8?
- MAC address prefix 1C:A0:B8 is registered to Hon Hai Precision Industry Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 1C:A0:B8 has a network interface built by Hon Hai Precision Industry Co., Ltd..
- What is the OUI 1C:A0:B8?
- 1C:A0:B8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hon Hai Precision Industry Co., Ltd.. It covers every address from 1C:A0:B8:00:00:00 to 1C:A0:B8:FF:FF:FF, or 16,777,216 addresses in total. It is also written 1C-A0-B8.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 1C:A0:B8:00:00:00 that is 1C:A0:B8 — 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 Hon Hai Precision Industry Co., Ltd. located?
- Hon Hai Precision Industry Co., Ltd. is listed at GuangDongShenZhen ShenZhen GuangDong CN 518109 in the IEEE OUI registry entry for 1C:A0:B8. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does Hon Hai Precision Industry Co., Ltd. own?
- Hon Hai Precision Industry Co., Ltd. holds 10 OUI prefixes in the IEEE registry, of which 1C:A0:B8 is one. A device made by Hon Hai Precision Industry Co., Ltd. could carry a MAC address from any of them.
