The IANA root zone record
IANA (Internet Assigned Numbers Authority) is the function, operated by ICANN through Public Technical Identifiers (PTI), that keeps the authoritative list of every top-level domain. If a TLD exists in the DNS root, it has exactly one IANA root zone record.
What the record tells you
- Sponsoring organisation
- The registry operator legally responsible for the TLD — the ground truth for "who runs this".
- Administrative & technical contacts
- Who ICANN talks to about the delegation.
- Name servers & DS records
- The authoritative servers for the TLD and its DNSSEC anchors.
- Registration & last-updated dates
- When the TLD was delegated and when its record last changed.
How dom4in uses it
Registry names, TLD types, and delegation status on our TLD pages are checked against IANA records — it's the source we trust over any marketing page.
Look up any TLD's record in the IANA Root Zone Database (external).
