Before You Generate
- Write the goal in one sentence before you open the tool.
- Gather your real material first: facts, numbers, names and constraints.
- Decide what done looks like - length, format, tone and audience.
- Set aside five uninterrupted minutes; context switching costs more than the task.

Mistakes to Avoid
- Assuming the vendor is the device owner
- Expecting a result for locally administered addresses
- Looking up a truncated address incorrectly
- Treating the vendor as proof of a model
A 10-Minute Practice Routine
- Two minutes: write the brief for a real task on your list.
- Three minutes: generate and read the result end to end.
- Four minutes: edit - real details in, generic lines out, opening rewritten.
- One minute: save the prompt and note one thing to change next time.
How to Know You Are Improving
Track edit time per result for two weeks. When it drops, your briefs are getting better. When it spikes, the cause is almost always a vague input - go back to the tip about writing the goal in one sentence.
Frequently Asked Questions
Does a MAC address work on the internet?
No - addresses are used on the local network segment, so this lookup matters for devices you can see locally.
Why does the vendor look unfamiliar?
Registrations record the company holding the prefix, which may be a parent firm rather than the brand on the device.
Can a MAC address be changed?
Yes - addresses can be spoofed, so treat the vendor as a hint rather than proof of identity.
Are my lookups stored?
No - lookups run on demand with nothing retained.
