Which company owns MAC address prefix 74:90:1F?

MAC address prefix 74:90:1F is registered to Ragile Networks Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 74:90:1F has a network interface built by Ragile Networks Inc..

What is the OUI 74:90:1F?

74:90:1F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ragile Networks Inc.. It covers every address from 74:90:1F:00:00:00 to 74:90:1F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 74-90-1F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:90:1F:00:00:00 that is 74:90:1F — 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 Ragile Networks Inc. located?

Ragile Networks Inc. is listed at 35649 Embassy common Fremont ca 94536 Fremont CA US 94536 in the IEEE OUI registry entry for 74:90:1F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
