FAQ
- Which company owns MAC address prefix 1C:DA:27?
- MAC address prefix 1C:DA:27 is registered to vivo Mobile Communication Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 1C:DA:27 has a network interface built by vivo Mobile Communication Co., Ltd..
- What is the OUI 1C:DA:27?
- 1C:DA:27 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to vivo Mobile Communication Co., Ltd.. It covers every address from 1C:DA:27:00:00:00 to 1C:DA:27:FF:FF:FF, or 16,777,216 addresses in total. It is also written 1C-DA-27.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 1C:DA:27:00:00:00 that is 1C:DA:27 — 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.
