Why "no DNS records" does not mean a domain is available

A name can be registered and still show no DNS records. Here is the check Namelizer uses instead.

A common shortcut for checking a domain is to look it up in DNS and call it free if nothing comes back. That is wrong. A registered domain with no nameservers set, or one that is parked without records, returns nothing in DNS and is still owned by someone.

Registration data lives at the registry, not in DNS. Registries publish it through RDAP, a standard, machine-readable lookup for registration data. If the registry says it has no record for the name, the name is likely available. If the registry confirms a record, it is registered.

Namelizer's availability check follows that order. An RDAP record means Registered. A clear "no record" answer means Likely available. If RDAP cannot answer, the result is Unknown, and missing DNS never upgrades it to available.

Likely available is still not a purchase guarantee. A name can be reserved, held back by the registry, or priced as a premium. Always confirm the price and availability at the registrar before you plan around a name.
