IANA Root Zone Database

Why do we need it?

We use it to check if an extension is valid/exists.

How does it work?


Want to read the parser code ? It’s here IANA()!

The root zone database is saved into the iana-domains-db.json file. It is formatted like below and is automatically merged for the end-user before each test run.

    "extension": "whois_server"

In-app, while testing for domain(s), we check if the extension is listed there before doing some extra verifications. If not, domain(s) will be flagged as INVALID.

How to generate it manually?

You can’t and should not as we are automatically generating it every 24 hours. But using the --iana argument will do the job on purpose.
