FAQ: Whois domain lookup

  • What is Whois?

    With the Whois Lookup service, you will receive publicly available information about any registered domain name. The Whois Information is retrieved from a standardized informational source, the so called Whois database. This service may help you in order to look up who owns a given domain respectively, whether it is still available or not.
  • What kind of data do I receive using the Whois Lookup?

    With the 1&1 Whois Service, you will get information about the current registrant of a particular domain. We offer two versions of the Whois Lookup, which differ in terms of the level of detail provided by the service. With the basic version, included on this page, you get the following Whois information:
    • Domain Name
    • Admin Organization
    • Admin Address (Street, City, State)

    Furthermore, we are offering you the option to request the complete Whois data for a specific domain under http://registrar.1and1.info/domains_raa/whois. In addition to the information above, you will find the following data:
    • Registry Domain ID
    • Registrar
    • Registrar URL
    • Creation Date
    • Registrar Registration Expiration Date
    • Registrar Abuse Contact Information (Email, Phone Number)
    • Domain Status
    • Registrant Name
    • Registrant Organization
    • Tech Contact Data (Name, Address, Phone Number, Email)
    • And many more
  • Why is the Whois Lookup useful?

    The Whois Lookup may help you in order to find out who owns or manages a domain. The Whois Service gives you direct access to available contact information of the respective domain owner. This can be useful in order to get in touch with the domain owner, if there are technical issues with the domain or if any legal rights have been violated. In addition to that, the Whois Lookup can be helpful if you intend to buy a domain name that has already been registered and you plan to submit an offer to the current domain owner.
  • Why is there no detailed Whois Information for some domain names?

    Depending on the registry that is responsible for the domain name you are interested in, you may receive different kinds of information using the Whois Lookup. The registry defines which records will be kept in the Whois database. Thus, it may happen that for some domain names no data or only a limited amount of information can be displayed. Furthermore, some domain owners use private domain registration where the personal data is kept confidential, hence these information cannot be accessed using the Whois Lookup.
  • What is the difference between the Whois Lookup and a Domaincheck?

    Meanwhile, the Domaincheck helps to identify whether or not a particular domain name is available, the Whois Lookup gives you access to further publicly available information regarding a registered domain. Should your requested domain name still be available, you can use both the Whois Service, as well as the Domaincheck in order to easily register your desired domain name with 1&1. Furthermore, we recommend suitable domain alternatives in case a particular domain name is registered already. Regardless of whether you use our Whois Lookup or Domaincheck, our main goal is to offer you the best support possible on your way to your desired domain name.
  • Can everyone see my information?

    The short answer is, yes. Generally, whenever you register a domain name, it is required to transmit specific personal data to the respective registry. These requirements may vary slightly from registry to registry. However, it is necessary that these personal data are publicly available for two reasons. Firstly, it offers the possibility to find out who is in charge of a specific domain from a technical perspective in case of technical issues. Secondly, it helps to identify a contact person in the event of infringement of third-party rights. Regardless of the requirements stated above, data protection is the top priority at 1&1 and we assure you that your data is safe with us.
  • How can I protect my personal data?

    In order to protect your personal data, we offer you free private domain registration which means that your name, address and phone number remains confidential. Instead of displaying your personal information in the Whois database, we will replace it with our data. Public domain registration information can often include details which are dangerous to your personal security. From names and phone numbers to addresses, don't allow your registration information to fall into the wrong hands. Stop spammers, data miners, telemarketers and others who may seek to misuse your information with private domain registration. However, please keep in mind that the 1&1 private domain registration can only be offered for some eligible top level domains like .com, .net, .org and .biz. 1&1 private domain registration gives you the peace of mind that your personal information is secure.

  • Does the WHOIS Lookup support .com domains?

    Yes, there is .com domain WHOIS support. Just like with other domain extensions, you can look up who owns a .com domain with WHOIS or whether certain .com domains are available. However, it should be noted that the information available during this .com domain lookup will depend on where the domain is registered; the WHOIS database is not an independent venture, but deals with multiple registrars that contribute information.

    These registrars manage different domain extension categories. For example, domain extensions are broken down into several categories: generic top-level domains (gTLD), new top-level domains (nTLD), and country code top-level domains (ccTLD). The domain extension .com (which stands for commercial) is a gTLD domain and is the most common gTLD, others include .org and .net. gTLDs are international domains and the information on these domains is handled by the Internet Corporation for Assigned Names and Numbers (ICANN). All of the available .com domain info in the database is made available publically. However, if the .com domain owner has opted for private domain registration, then only a limited amount of information will be made available in the .com domain WHOIS lookup search results.
