What is the OUI 98:4A:47?

98:4A:47 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to CHG Hospital Beds. It covers every address from 98:4A:47:00:00:00 to 98:4A:47:FF:FF:FF, or 16,777,216 addresses in total. It is also written 98-4A-47.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 98:4A:47:00:00:00 that is 98:4A:47 — 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 CHG Hospital Beds located?

CHG Hospital Beds is listed at 1020 Adelaide St S London ON CA N6E 1R6 in the IEEE OUI registry entry for 98:4A:47. This is the address the organization registered with the IEEE, which may differ from its current operating address.
