Domain transfer, owner change and IDN: The big domain glossary part 5

How can a domain be moved to another provider? How does a domain transfer to a new owner? And what does IDN stand for? Answers to these and other questions can be found in the fifth part of the 1&1 Domain Glossary.

Domain Name Transfer

Domain transfer is the process of moving a registered web address to a new provider like 1&1. In 2014, ICANN instituted binding rules of the transfer procedure for all registrants:

  1. Initially, the domain owner verifies himself to the future registrar.
  2. After that, he files a domain transfer application to the previous registrar and requests a corresponding authorization code, which is also called AuthInfo.
  3. The future registrar forwards the request to the superordinate registry.
  4. The registry then contacts the current registrar and requests approval (if no reply is received within five days, it’s rated as approval).
  5. The current registrar sends an e-mail to the domain owner or admin-C.
  6. The administrative contact now confirms the transfer (if the status remains unchanged, this is considered a rejection).
  7. The current registrar forwards the confirmation or rejection to the superordinate registry.
  8. As a last step, the registry completes the transfer to the new domain-provider in its database.

The duration of the domain transfer depends on the selected domain transmission. As a rule, the actual domain relocation is completed within 14 days. For full instructions, find out how to move your domain at 1&1 in just 3 steps.

Domain Ownership Transfer

When a change of ownership occurs, the current domain owner assigns his rights to his domain to a new owner. The existing contract is terminated by the current domain owner and a new contract between the future owner and the registry or registrar is closed. Here you can find out how you can make the change step by step at 1&1 and what should be observed.

Multi-Year Renewal

If you have found the ideal web address for your project, you might want to keep it forever. But the domain name registries limit how many years you can register your domain name in advance. The registration period varies from one year to a maximum of ten years. At 1&1 you have the possibility to secure your perfect domain directly for up to five years.

Private domain registration

For many domain registrations, the domain name registries and registrars are obliged to announce the registration data via WHOIS databases. The “Private Domain Registration” service shields the confidential data of a domain owner and publishes the contact details of the trustee instead. This service protects the personal data from misuse by criminal third parties. The domain owner holds of course, all rights to his domain, even if the data of a trustee are published. In detail, our domain expert Thomas Keller explains in this article why the “Private domain registration” is a useful service.


IDN stands for international domain names (internationalized domain names). They are also referred to as special characters domains. Correspondingly, these are domain names that contain ligatures, diacritics, or letters from other alphabets than the Latin alphabet. Originally, special characters were not provided in the domain name system (DNS); they were first introduced by the Internet standard “Internationalizing Domain Names in Applications” (IDNA). In principle, almost all Unicode characters in IDNs are allowed. However, each domain name registry or NIC regulates which characters it allows for the registration of their domains.


Trademark Clearinghouse, or TMCH, gives companies and brand owners the opportunity to have their trademark data entered into a centralized database. With the introduction of the new top level domains (nTLDs), the domain name system has been significantly expanded and brands and companies have accordingly a larger selection of web addresses available. On the other hand, the threat to the intellectual property of domain owners increases with the extension of the TLD spectrum. It offers more opportunities for cybersquatting and other activities that potentially violate copyright law. As an organization that monitors the domain name assignment on the Internet, ICANN has developed TMCH mechanisms with which domain owners can protect their trademark rights during DNS expansion.


This abbreviation stands for “Whois Data Reminder Policy”. This is an ICANN guideline for registrations, which will stop them from keeping the Whois database up-to-date. Each registrar sends out a mailing to all domain owners once a year, where they are asked to check their current Whois data. The reason for this is that incorrect Whois data can be a reason for deleting a domain. Therefore, the sending of this mail is mandatory for all registrars once a year per domain.

E-mail Verification

A validation of the e-mail address registered for the domain owner is prescribed by the ICANN. In the case of registration, domain transfer or subsequent modification of the e-mail contact addresses of the domain owner, the domain owner can be requested to provide additional confirmation of the details. This e-mail verification is necessary if the registered contact address of the domain owner is not listed in the system; It is also the case, for example, for new customers. For the verification, an e-mail with a verification link will be sent to the domain owner’s address.
