DNS Lookup/WHOIS

Every registered domain has a public registration record showing when it was created, when it expires, which registrar manages it and which name servers answer for it. That record answers a surprising number of practical questions, from "is this domain actually about to expire" to "does this supplier website predate the invoice they sent us".

Administrators use WHOIS during migrations to confirm which registrar holds a domain and where its name servers point. Buyers use it to see whether a domain they want is registered and when it might lapse. Security and fraud teams use creation dates as a signal, because a domain registered three days ago and sending invoices deserves scrutiny that a fifteen-year-old one does not.

Privacy rules have changed what you see. Since GDPR, personal contact details for many domains are redacted behind a privacy service, so expect organisational and technical fields rather than an individual's name and address. The structural information, dates, registrar and name servers remains available and is usually what matters.

How to use the DNS Lookup/WHOIS

1. Enter the domain name, without the protocol prefix.
2. Run the lookup to retrieve the public registration record.
3. Check the creation and expiry dates.
4. Note the registrar and the name servers currently authoritative for the domain.
5. Copy the record if you need it for a migration plan or an investigation note.

Examples

• An administrator confirms which registrar holds a domain before starting a transfer.
• A finance team checks the creation date of a supplier domain that appeared on a suspicious invoice.
• A business owner discovers their domain expires in three weeks and renews it in time.

Frequently asked questions

Why are the contact details hidden?

Privacy regulations and registrar privacy services redact personal information for many domains. Structural details such as dates and name servers remain public.

What do the name servers tell me?

They show which DNS provider is authoritative for the domain, which is where records must be changed for the change to take effect.

Does a lookup mean the site is trustworthy?

No, but a very recent creation date on a domain making commercial claims is a meaningful warning sign worth investigating.

Why did my lookup return nothing?

The domain may be unregistered, use an extension with restricted WHOIS access, or be temporarily rate limited by the registry.
