Which company owns MAC address prefix 98:8E:DD?

MAC address prefix 98:8E:DD is registered to TE Connectivity Limerick in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 98:8E:DD has a network interface built by TE Connectivity Limerick.

What is the OUI 98:8E:DD?

98:8E:DD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TE Connectivity Limerick. It covers every address from 98:8E:DD:00:00:00 to 98:8E:DD:FF:FF:FF, or 16,777,216 addresses in total. It is also written 98-8E-DD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 98:8E:DD:00:00:00 that is 98:8E:DD — 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 TE Connectivity Limerick located?

TE Connectivity Limerick is listed at International Science Centre, Block 1 Castletroy Co. Limerick IE in the IEEE OUI registry entry for 98:8E:DD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
