How it works

Three steps, a few seconds.

01

We find the right registry

The IANA RDAP directory tells us which registry runs the domain's extension (.com, .ca, .org and so on).

02

We ask the registry

The registry returns the official record. For many extensions we also ask the registrar for extra detail.

03

We flag the risks

Expiry within 60 days, missing transfer locks and no DNSSEC are called out so you can act.

FAQ

Questions, answered.

Why is the owner's name hidden?

Most registries and registrars redact personal contact details for privacy. Registrar, dates and nameservers are still public.

What is RDAP?

The Registration Data Access Protocol. ICANN retired the old WHOIS requirement for generic domains in January 2025, and RDAP is now the official source.

What does clientTransferProhibited mean?

It is a registrar lock that stops the domain from being transferred away without your approval. You want it on.
