All the information you need to know about the RDAP protocol.

The Registry Data Access Protocol (RDAP) is an updated version of the popular Whois service. It was created in 2015 with the goal of solving some of the shortcomings that Whois presented and to improve its consultation service.

We tell you about it here with more details.

Like Whois, its fundamental function is to provide information related to domain registration data: owner, registration and expiration date, associated DNS servers, etc. As users, we may be interested in accessing this information if we want to contact the domain administrator to negotiate your purchase with him, to inform him of possible technical problems that we have detected, or because we want to report any type of irregular behaviour related to your domain.

In addition, the RDAP protocol also provides information about IP addresses or Autonomous Systems (ASN).

To consult the registration data of a domain, you just have to enter the domain you want in the search engine that we provide and click on See RDAP.

Keep in mind that the search engine will only offer you information about the domains that are registered in dinahosting.

In most extensions, such as .COM or .NET, you will be able to update your information in a moment from the Domains section of your dinahosting Control Panel. Other domains, such as .ES, have some requirements. Call us or write to us and we will indicate the steps to follow.

Here's more information on domain contact changes.

RDAP is the improved version of the Whois tool. Its objective is to present the information of each query in a more structured and secure way, and of course complying with the new General Data Protection Regulation (GRPD). Whereas Whois returns the information in plain text and without encoding format, RDAP does so in JSON format and presents it as a table. In addition, the queries made through the RDAP protocol are made through a secure connection or HTTPS.

Here are the main differences between Whois and RDAP.

Yes. Both protocols will coexist until ICANN, as the ultimate responsible for managing domains worldwide, determines otherwise.
