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

In the fifth part of our 1&1 Domain Glossary we seek to address three key questions: How can a domain be moved to another provider? How does a domain transfer to a new owner? What does IDN stand for?

Domain Name Transfer

A Domain transfer is the process when domain owners move a registered web address from their current provider to a new provider, like 1&1. It was only in 2004 that the Internet Corporation for Assigned Names and Numbers (ICANN) laid down binding rules for the transfer procedure of all registrants:

  1. Initially the domain owner legitimates himself to the future registrar.
  2. After that, he applies to the previous registrar for the move to the domain and requests a corresponding authorization code, which is called AuthInfo.
  3. The future registrar forwards the request to the superordinate registry.
  4. This registry then contacts the current registrar and requests it to approve or reject (if no reply is received within five days, the transfer is rated as approved).
  5. The current registrar sends an e-mail to the domain owner or admin-C.
  6. The administrative contact person now confirms the transfer (if the confirmation remains, 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 changes 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. Read here, 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 the 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 the registrar is completed. 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 secure it for a longer period of time. However, the domain name registries limit the number of years you can register your domain name in advance. For example, 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 for up to five years.

Private domain registration

For many domain registrations the domain name registries and registrars are obligated to announce the registration data via the WHOIS database. However, a “Private Domain Registration” service shields the data of a domain owner and publishes only the contact details of the trustee instead. The advantage is that this service protects personal data from misuse by criminal third parties. Nevertheless, the domain owner maintains all rights to his domain, even if the data of a trustee is published. For further information, 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) and 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.


The Trademark Clearinghouse, or TMCH, offers companies and brand owners the opportunity to have their trademark data entered into a centralised database. With the introduction of the new top level domains (nTLDs), the domain name system (DNS) has been significantly expanded and brands and companies have been offered a larger selection of available web addresses. However, the extension of the TLD spectrum does increase the threat to the intellectual property of domain owners. This threat is increased because the extension 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 where each registrar sends out a mandatory email 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.

E-mail Verification

A validation of the e-mail address registered for the domain owner is a mandatory measure prescribed by ICANN. In the case of registration, domain transfer or subsequent modification of the e-mail contact addresses of the domain owner, the domain owner will be requested to provide additional confirmation of details. This e-mail verification is necessary for new customers or if the registered contact address of the domain owner is not listed in the system. For final verification, an e-mail with a verification link will be sent to the domain owner’s address. You want to know more about the structure of domains, their technical background and the institutions of the Domain sector? You’ll find a lot of information in the other parts of the domain glossary:

The last part will be about premium domains, domain parking and threats like domain grabbing and cybersquatting.
