What is the OUI 80:75:1F?

80:75:1F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SKY UK LIMITED. It covers every address from 80:75:1F:00:00:00 to 80:75:1F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 80-75-1F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 80:75:1F:00:00:00 that is 80:75:1F — 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.
