Frequently Asked Questions
Common questions and answers about Whois queries
What is Whois query?
Whois query is a protocol and service used to query domain registration information. Through Whois query, you can obtain detailed information such as domain registrar, registration date, expiration date, domain holder contact information, DNS servers, etc. This is very useful for domain management, network security investigation, trademark protection, etc. Our Whois query tool can quickly and accurately provide you with this important information.
How to query domain expiration date?
Using our Whois query tool, simply enter the domain name you want to query (e.g., example.com) in the search box and click the query button. In the returned results, you will see the "Expiration Date" field, which is the expiration date of the domain. It is very important to know the domain expiration date in time to avoid domain expiration, and it is recommended to query regularly and set reminders.
Why can't some domains query detailed information?
Reasons why some domains may not be able to query detailed information include: 1) The domain has enabled privacy protection service, hiding the real information of the holder; 2) Some top-level domains (such as .edu, .gov) have special query restrictions; 3) Domain registrars have implemented access restrictions or rate limits; 4) The domain may not have completed the registration process. Even if you cannot obtain complete information, you can still view basic registration status and DNS information.
Is domain holder information accurate?
Domain holder information in the Whois database is usually accurate, because ICANN (Internet Corporation for Assigned Names and Numbers) requires domain registrars to verify the authenticity of registrant information. However, with the popularity of privacy protection services, many domain holders choose to use proxy services to protect personal privacy. In this case, the information displayed may be the agent's information rather than the real holder's information. For commercial domain queries, it is recommended to verify with multiple data sources.
Which domain suffixes are supported?
Our Whois query tool supports almost all mainstream top-level domain suffixes, including but not limited to: generic top-level domains (.com, .net, .org, .info, .biz), country code top-level domains (.cn, .us, .uk, .de, .jp), new generic top-level domains (.tech, .app, .dev, .io, .ai), etc. A total of more than 1000 different domain suffixes are supported. If you encounter a special suffix that is not supported, please contact us and we will add support as soon as possible.
How to determine if a domain is available for registration?
You can quickly determine the registration status of a domain through Whois query. If the query result shows "No matching record" or "Domain not registered", it usually means the domain can be registered. If detailed registration information is displayed, it means the domain has been registered. It should be noted that some domains may be in reserved status, redemption period or deletion period. Although these domains cannot query conventional information, they still cannot be registered normally. It is recommended to confirm at the domain registrar.
What is the role of DNS server information?
DNS server information is very important in Whois query results. It tells you which DNS servers the domain uses to resolve the domain name to an IP address. Through DNS server information, you can understand: 1) Whether the domain is in use (active DNS indicates the domain is in use); 2) Which service provider the website may be hosted on (different DNS service providers have different naming rules); 3) The technical management of the domain. This is very helpful for website migration, troubleshooting and competitive analysis.
How to protect my domain privacy?
If you are concerned about your personal information being publicly available in Whois queries, you can consider the following privacy protection methods: 1) Use domain privacy protection services, which are provided by most domain registrars; 2) Use corporate information to register domains instead of personal information; 3) Choose domain suffixes that support privacy protection; 4) Regularly check your domain Whois information to ensure privacy settings are correct. It should be noted that some domain suffixes (such as .us) may not support complete privacy protection. Please understand the relevant policies before registration.
