Common Questions
Whois Lookup FAQ

A Whois lookup queries the domain registration database to retrieve publicly available information about a domain — who registered it, when, which registrar manages it, when it expires, and which nameservers it uses. Our tool uses RDAP (Registration Data Access Protocol), the modern structured replacement for the old raw WHOIS protocol.

Since GDPR came into effect in 2018, most domain registrars redact personal information (name, email, address, phone) from public Whois records to protect domain owner privacy. Many registrars also offer "privacy protection" services that replace owner details with the registrar's own contact information. This is completely normal and does not indicate anything suspicious about the domain.

"clientTransferProhibited" means the domain is locked at the registrar level, preventing it from being transferred to another registrar without first being explicitly unlocked by the owner. This is a standard security measure that prevents unauthorised domain transfers. Most registered domains will show this status — it is a good thing. Other common statuses include "serverTransferProhibited" (registry-level lock) and "active" (the domain is functioning normally).

DNSSEC (DNS Security Extensions) adds a cryptographic signature layer to your DNS records, protecting against DNS hijacking and cache poisoning attacks. If your domain shows "Unsigned", it means DNSSEC is not enabled. For most small to medium businesses it is optional, but for domains handling financial transactions, healthcare data, or sensitive communications, enabling DNSSEC adds a meaningful layer of protection. Contact your domain registrar to enable it.

Domain age matters for several reasons. From an SEO perspective, older domains often carry more link equity and tend to rank more easily than brand-new domains. From a trust and email deliverability perspective, email sent from newly registered domains is treated with more suspicion by spam filters — domains registered recently have no sender reputation history. From a business due-diligence perspective, checking domain age helps verify whether a company is as established as it claims.

This can happen for a few reasons: (1) The domain may not be registered yet. (2) The TLD (extension) may not be supported by our RDAP lookup — we currently cover .com, .net, .org, .in, .io, .co, .uk, .de, .au, .ca, .fr, .eu, .us, .app, .dev, .ai, .me, .tech, and others. Very new or country-specific TLDs may not have an RDAP service yet. (3) The domain may be in a redemption or pending delete period. Try entering just the domain and extension without www or https.
