{"openapi":"3.1.0","info":{"title":"MAC Vendor API","version":"1.0.0","description":"Identify the manufacturer behind any MAC address. Look up a MAC or OUI to get the assigned vendor, its short name and the exact assignment block (/24, /28 or /36) using the official IEEE registry, search the registry by vendor name to find all of a company’s OUIs, or generate random valid test MAC addresses for a given vendor. MAC addresses are accepted in every common format — colon, hyphen, dot or bare hex — and bare OUIs work too. Built on the open IEEE OUI dataset (~57,000 assignments) and served entirely in-memory, so responses are instant and the service is always available. Ideal for network scanning and monitoring, IoT and device identification, security and asset inventory, NAC and devops tooling.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/macvendor-api","description":"oanor
