Which company owns MAC address prefix 48:23:35?

MAC address prefix 48:23:35 is registered to Dialog Semiconductor Hellas SA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 48:23:35 has a network interface built by Dialog Semiconductor Hellas SA.

What is the OUI 48:23:35?

48:23:35 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Dialog Semiconductor Hellas SA. It covers every address from 48:23:35:00:00:00 to 48:23:35:FF:FF:FF, or 16,777,216 addresses in total. It is also written 48-23-35.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 48:23:35:00:00:00 that is 48:23:35 — 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 Dialog Semiconductor Hellas SA located?

Dialog Semiconductor Hellas SA is listed at Achileos 8 & Katsoni Str Kalithea, Athens GR 17674 in the IEEE OUI registry entry for 48:23:35. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Dialog Semiconductor Hellas SA own?

Dialog Semiconductor Hellas SA holds 2 OUI prefixes in the IEEE registry, of which 48:23:35 is one. A device made by Dialog Semiconductor Hellas SA could carry a MAC address from any of them.
