What is the OUI B8:E5:89?

B8:E5:89 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Payter BV. It covers every address from B8:E5:89:00:00:00 to B8:E5:89:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-E5-89.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:E5:89:00:00:00 that is B8:E5:89 — 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 Payter BV located?

Payter BV is listed at Rozenlaan 115 Rotterdam Zuid-Holland NL 3051 LP in the IEEE OUI registry entry for B8:E5:89. This is the address the organization registered with the IEEE, which may differ from its current operating address.
