1. What is a domain name?

It is a set of alphanumeric characters used to identify a particular computer on the Internet.

Each computer on the Internet has a unique numerical address called Internet Protocol Address (IP), as these addresses are difficult to remember the DNS allows a name to be used instead of the IP address and the DNS translates the Domain Name in IP addresses so that communication between the different computers connected to the Internet is possible.

In other words, a domain name is a simple form of Internet address designed to allow users to easily locate sites on the Internet.

2. What is the structure of a domain name?

A domain name consists of two or more tags separated by the “.”



  • The first field (mydomain) corresponds to the name, acronym or abbreviation chosen by the person or organization to which the domain name is delegated.
  • The second field (com) corresponds to the classification or subdomain under which the name is registered, depending on the use to be made of it or the preference of the end user.
  • The third field (do) corresponds to the top level domain under which the register is made.

In our case, .do are the letters assigned to the Top Level Domain for the namespace corresponding to the Dominican Republic, in the Internet Domain Name System (DNS). These letters are taken from the country code table according to ISO 3166-1 alpha 2 (standard established by the International Organization for Standardization, which defines codes for the representation of countries and their divisions).

3. What does registering a domain name mean? Why do I need it?

The Domain Name System (DNS) consists of a hierarchically organized directory of all domain names and their corresponding computers registered to a particular person or company using the Internet. When registering a domain name, it is associated with the computer on the Internet that is designated and from that computer can be implemented services on the Internet for that domain name, ie a domain name allows you to have presence on the Internet, for example, create a website, email, etc.

4. Can I register a domain name directly under .DO?

Yes, as of December 2009 NIC .DO has started registering second level domains (directly under .do).

5. Can I choose any name for my domain?

Yes, however, you must ensure that you do not violate the rights of third parties.

Regarding the domain name itself, the following should be observed:

  • The total length of the domain name must not exceed 63 characters.
  • Valid characters are numbers (0-9), English alphabet letters and hyphen (-).
  • Domain names should not begin or end with the dash (-) or carry two dashes (-) in a row.
6. What is a Registrar?

9. What is the difference between domains registered under .DO and .COM, .NET, etc.?

When registering a domain in .do, we are identifying with the Dominican Republic, technically there is no difference between registering a domain .com or .do since the Internet is global and both can be accessed from anywhere on the Internet.

11. Who owns the domain?

When you apply for registration of a domain name, this domain is delegated to the registrant for a period of time that can be extended by renewal. Domains are not sold therefore should not be considered as a property of the applicant. However, during the time of delegation of the name, the person or organization to which the name is delegated shall be considered as the holder or registrant.

12. What is the importance of registering the data of the Domain Holder?

The owner or Registrant of a domain name is the one who is granted the rights and responsibilities for the use of the domain, by registering the actual data of the owner, we adhere to the best practices and facilitate the management of the domain.

13. How do I know that I am the owner a domain name?

Your name or your company name must appear in the information related to the Domain Name Holder or Registrant in the NIC .DO database. If this is not the case, you should contact us immediately and document the way in which you can update this information.

You can check the NIC .DO’s Whois.

If your domain name has expired you should contact your Registrar or reseller for the renewal. If you do not know who your registrar is, you can search the WHOIS database, the results will show the registrar responsible for registering your domain name so that you can contact him.

When a Domain Name is not renewed at the expiration date, before being eliminated it goes through the following stages / status:

  • Renewal grace period, status “Suspended”, are 30 days after the expiration date of a Domain Name, during this time the emails and other applications will stop working.
  • Redemption Grace Period, “Pending Deletion” Status, if a domain name is not Renewed within the Renewal Grace Period, it is queued for deletion for a period of 15 days. During this time the domain can be restored at an additional cost to the renewal fee.

At the end of this 45-day period, the domain is released and can be registered by anyone.

19. Why are some domain names not available for registration?

NIC .DO maintains a list of names that can not be registered as domain names because they are related or refer to:

  • The structure of IANA
  • The structure of ICANN
  • Internet Terms
  • Existing, proposed or pending gTLD names by the competent authority.
  • Terms reserved for the operation of NIC .DO

There is no application process for these names.

20. What is Whois?

The WHOIS service is a public access tool that allows you to consult technical and contact information of registered domain name holders. Anyone wishing to know who is behind the domain name of a website can request that information through a WHOIS query. Registrars and Registries are responsible for collecting and making such data available to the public in accordance with the terms of the agreements they have concluded with ICANN.

WHOIS is used to perform specific functions relating to the operation of domain names. For example, the WHOIS system is used to support the transfer or removal of a domain name, or to facilitate administrative procedures relating to trademark dispute resolution, to identify persons or entities responsible for the operation of a Network on the Internet.
