Which company owns MAC address prefix 34:BD:FA?

MAC address prefix 34:BD:FA is registered to Cisco SPVTG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 34:BD:FA has a network interface built by Cisco SPVTG.

What is the OUI 34:BD:FA?

34:BD:FA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Cisco SPVTG. It covers every address from 34:BD:FA:00:00:00 to 34:BD:FA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 34-BD-FA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 34:BD:FA:00:00:00 that is 34:BD:FA — 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 Cisco SPVTG located?

Cisco SPVTG is listed at 5030 Sugarloaf Parkway Lawrenceville GA US 30044 in the IEEE OUI registry entry for 34:BD:FA. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Cisco SPVTG own?

Cisco SPVTG holds 41 OUI prefixes in the IEEE registry, of which 34:BD:FA is one. A device made by Cisco SPVTG could carry a MAC address from any of them.
