   summary

   Before: "This is a free web tool and API for looking up MAC addresses or OUIs to find their registered vendor, IEEE assignment, block range, country, and address type. It provides detailed explanations beyond just vendor names, including randomization confidence and IPv6 derivations, with no account required for web lookups and a free API tier."

   After: "This is a free web tool and API for looking up MAC addresses or OUIs to find their registered vendor, IEEE assignment, block range, country, and address type. It provides detailed explanations for each lookup, including randomization indicators and IPv6 derivations, with no account required for the web tool and a free tier for the API."

   useCases

   Before: ["Network access control and IoT fleet management requiring accurate MAC vendor data."]

   After: ["Integrate MAC address lookups into production environments via hosted or self-hosted API for network access control and IoT fleet management."]

   walkthrough

   Before: ["Lookup a MAC address via the free web tool or API to receive vendor and address type details with explanations.","Sign up for a free API key to access 1,000 free lookups per month with full response data."]

   After: ["Enter any MAC address or OUI in any format to get detailed vendor and address information including block range and randomization confidence.","Use the hosted API with an API key for production volume lookups, with rate limits and monthly quotas depending on plan.","Optionally install the self-hosted API and sync engine on your own infrastructure to keep lookups local and avoid third-party API calls and billing."]
