FAQ
- Which company owns MAC address prefix 00:26:BD?
- MAC address prefix 00:26:BD is registered to JTEC Card & Communication Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:26:BD has a network interface built by JTEC Card & Communication Co., Ltd.
- What is the OUI 00:26:BD?
- 00:26:BD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to JTEC Card & Communication Co., Ltd. It covers every address from 00:26:BD:00:00:00 to 00:26:BD:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-26-BD.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 00:26:BD:00:00:00 that is 00:26:BD — 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 JTEC Card & Communication Co., Ltd located?
- JTEC Card & Communication Co., Ltd is listed at Dabo Bldg, 4F, 61-1, Gyesu-dong, Sosa-gu Bucheon Gyunggi-do KR 422-070 in the IEEE OUI registry entry for 00:26:BD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
