About Root Zone Database
Browse all top-level domains (TLDs) — gTLDs, ccTLDs and their registry operators.
Root Zone Database is a browsable index of the top level domains published in the DNS root zone, including generic domains, country codes and the newer sponsored extensions. Each entry shows the domain, what it stands for, its status in the root, the sponsoring organisation and the registry operator responsible for running it. Search by name or filter by category to find who administers an extension, whether a domain is active or retired, and which operator to contact about policies. The data comes from the public root zone, is refreshed regularly and is free for anyone researching domain names.
How to Use Root Zone Database
- Enter the host, IP address, URL or port you want to inspect.
- Choose any options the tool offers (protocol, count, depth).
- Run the check — results appear as the browser completes the request.
- Copy the report or note down the details you need.
Key Features
- No terminal or admin tools needed — everything happens in the page.
- Clear, readable results instead of raw command output.
- Checks run from your browser, reflecting what a real visitor experiences.
Frequently Asked Questions
Where does the Root Zone Database get its list of domains?
The entries are taken from the public DNS root zone, which is the authoritative list of every top level domain currently delegated. Each row carries the registry operator, sponsoring organisation and current status, so you can see who runs an extension without hunting through separate registrar sites. Country codes, generic domains and sponsored extensions all appear in the same list, and the data is refreshed as the root changes.
Is Root Zone Database free to use?
Yes. Root Zone Database is completely free with unlimited use — no account, download or payment required.
Is my data uploaded to a server?
No. Root Zone Database runs entirely in your browser. Your inputs are never sent to our servers or stored anywhere.
Does Root Zone Database work on mobile?
Yes. The interface is fully responsive and works in any modern browser on Android, iPhone, tablets and desktops.
