Which company owns MAC address prefix 58:04:54?

MAC address prefix 58:04:54 is registered to ICOMM HK LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 58:04:54 has a network interface built by ICOMM HK LIMITED.

What is the OUI 58:04:54?

58:04:54 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ICOMM HK LIMITED. It covers every address from 58:04:54:00:00:00 to 58:04:54:FF:FF:FF, or 16,777,216 addresses in total. It is also written 58-04-54.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:04:54:00:00:00 that is 58:04:54 — 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 ICOMM HK LIMITED located?

ICOMM HK LIMITED is listed at SUITES 2302-6, 23/F GREAT EAGLE CTR 23 HARBOUR RD WANCHAI HK NA in the IEEE OUI registry entry for 58:04:54. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does ICOMM HK LIMITED own?

ICOMM HK LIMITED holds 2 OUI prefixes in the IEEE registry, of which 58:04:54 is one. A device made by ICOMM HK LIMITED could carry a MAC address from any of them.
