WHOIS Lookup
Check public domain
registration details.
Use the APN Cloud WHOIS lookup to check public domain registration details, including the current registrar, registration and expiration dates, nameservers and registry status. Availability of individual records depends on the domain registry and its privacy policies.

Domain WHOIS explained
What is a WHOIS lookup?
WHOIS is a system used to retrieve publicly available registration information about a domain name. A domain WHOIS lookup can help you identify the registrar managing a domain, review important registration dates, inspect nameservers and understand registry status codes.
Domain registration information is maintained through registrars and registries. The exact information returned can vary by domain extension, registry policy and the type of registration data that is publicly available.
Personal registrant information may not appear in a public lookup. Privacy services, data-protection requirements and registry policies can hide names, email addresses, phone numbers and postal addresses. Modern registration lookups may also use RDAP to retrieve structured domain data.

How to read a domain WHOIS record
Registrar
The registrar is the company responsible for managing the domain registration. Knowing the current registrar is useful when renewing a domain, changing account settings or preparing to transfer the domain to another registrar.
Registration date
The creation or registration date shows when the domain was originally registered, when that information is published by the registry. It can provide useful context about how long the domain has existed.
Expiration date
The expiration date shows when the current registration period is scheduled to end. Domain owners should normally renew before this date to reduce the risk of expiration or service interruption.
Nameservers
Nameservers identify the DNS infrastructure currently serving the domain. They are important when moving a website, changing DNS providers or preparing a domain transfer.
Registry status
Registry status codes can show whether a domain is active, locked, on hold, pending transfer or subject to another restriction. These codes are especially useful when diagnosing transfer problems.
Registrant information
Some registration records may include registrant information. However, many registries and registrars hide personal contact details because of privacy rules or domain privacy services.
WHOIS privacy
Why some domain registration details are hidden
Privacy by default
Many registries and registrars restrict public access to personal registration data because of privacy and data-protection requirements.
WHOIS privacy services
Domain privacy services can replace a registrant's personal name, email address, phone number or postal address with proxy information.
Different registry policies
Every domain extension can follow different publication rules, so a .com domain may expose different information from a country-code domain.
Limited data is normal
Missing personal information does not automatically indicate a problem. A legitimate domain can have very little public registrant information.
Common WHOIS uses
When a domain lookup can help
Check a domain before buying
Review the registrar, registration dates, nameservers and status of an existing domain before discussing a purchase or ownership transfer.
Prepare for a domain transfer
Check whether the domain appears active and review transfer-related status codes before starting a registrar transfer.
Investigate DNS configuration
Nameserver information can help you identify where DNS is currently managed before moving a website or changing DNS providers.
Review registration history
Creation and update dates can provide basic context about how long a domain has existed and when its registration record was last changed.
Domain status codes
Common registry statuses you may see
clientTransferProhibited
The registrar has placed a transfer lock on the domain. The lock normally needs to be removed before a transfer to another registrar can proceed.
serverTransferProhibited
The registry is preventing the domain from being transferred. This status may require assistance from the registrar or registry.
clientHold
The registrar has placed the domain on hold. A domain with this status may stop resolving through DNS until the underlying issue is resolved.
serverHold
The registry has placed the domain on hold. DNS resolution may be affected until the registry-level restriction is removed.
pendingTransfer
A registrar transfer has already been requested and is currently being processed or waiting for completion.
redemptionPeriod
The domain may have expired and entered a recovery stage. Restoring it can require additional action and may involve a redemption fee.
WHOIS and RDAP
Two ways domain registration data may be provided
WHOIS
WHOIS is the traditional system used to retrieve public domain registration information. The format and amount of information can vary significantly between registries and domain extensions.
RDAP
RDAP, or Registration Data Access Protocol, provides registration information in a structured format. It can include registrar data, dates, nameservers, registry status values and other registration details.
APN Cloud focuses on presenting available registration information in a readable format. The information you see depends on what the relevant registrar, registry or registration-data service makes available for the domain.
Domain transfer checks
Review your domain before starting a registrar transfer
Before you transfer
WHOIS data can help identify transfer problems early
Before transferring a domain to another registrar, review the available registration record for signs that could affect the transfer. An expired domain, transfer lock, registry hold or pending transfer status can require additional action before the process can continue.
Nameservers also deserve attention before a transfer. A registrar transfer and a DNS change are separate operations. Recording your current nameservers and DNS configuration can help you avoid unnecessary disruption to websites, email and other services.
If the transfer requires email approval or another form of confirmation, make sure the appropriate account or contact method is accessible before submitting the request. Requirements can vary by registrar, registry and domain extension.
WHOIS FAQ
Frequently asked questions about domain lookups
What is a WHOIS lookup?
A WHOIS lookup retrieves publicly available registration information about a domain name. Depending on the registry, the result may include the registrar, registration dates, expiration date, nameservers, registry status and limited contact information.
Can I find the owner of a domain with WHOIS?
Sometimes, but not always. Many domain registrations use privacy protection, proxy contact information or registry privacy policies that prevent personal registrant details from being displayed publicly.
How can I check when a domain expires?
Enter the domain name in the lookup tool above. If the registry publishes an expiration date, APN Cloud will display it with the other available registration details.
What does clientTransferProhibited mean?
It generally means the registrar has locked the domain against transfer. The lock normally needs to be removed before the domain can be transferred to another registrar.
Why does a WHOIS lookup show limited information?
The registry may restrict public data, the registrant may use a privacy service, or the domain extension may publish only a limited registration record.
Does changing registrars change my website?
A registrar transfer does not normally change the website itself. However, you should verify nameservers and DNS settings before transferring so that website and email services continue using the intended configuration.
Can I transfer an expired domain?
Transfer eligibility depends on the domain extension, current registrar and lifecycle status. If a domain is expired, on hold or in redemption, you may need to resolve that condition before a transfer can proceed.
Are WHOIS and DNS the same thing?
No. WHOIS and RDAP provide domain registration information, while DNS determines how the domain connects to websites, email servers and other internet services.
Why are nameservers shown in a WHOIS lookup?
Nameservers indicate which DNS servers are authoritative for the domain. They can help you understand where DNS is currently managed before making hosting or domain changes.
Is WHOIS information always accurate?
WHOIS and RDAP results reflect information supplied through registrars and registries. Some fields may be hidden, delayed, unavailable or formatted differently depending on the domain extension and registry.
Need a new domain instead?
Search for your preferred domain name on APN Cloud, compare available extensions or start a transfer for a domain you already own.
