Frequently asked questions

Is there an API?

Some lookups expose a JSON endpoint; the full list is on the Network Tools → API reference page.

Could the tables be out of date?

Specifications evolve. These pages list the common entries and note the last update — report anything wrong.

Why not everything?

We keep the high-frequency entries to hold page weight and load time down.
