DO is the Country Code Top Level Domain for the Dominican Republic, a nation on the island of Hispaniola and also the 2nd biggest Caribbean nation with around 10 million people.
Having your name registered in a .DO is significant if you are planning to reach and communicate with the audience in the Dominican Republic. It can also be a strategic move as the word “DO” means different things in different languages. In English “DO” is the most used action verb, with plenty of meanings attached to it and possible usages. In Spanish, “DO” is the end of all verbs in past participle.
Besides, a domain name in .DO has much more impact than a domain ending with the second level domain .COM.DO, more centered around commercial organizations.
