Answers about Dominican registration options, naming rules, required data, transfers, expiry stages, local use, and reseller management.
.DO is the country-code top-level domain for the Dominican Republic and is administered by NIC.DO of the Pontificia Universidad Católica Madre y Maestra. You can check .DO domain availability before starting registration.
NIC.DO states that direct .DO names can be used by any sector or person. Registrants must provide accurate contact information and comply with registry policies and third-party rights before completing a domain registration request.
NIC.DO also offers .COM.DO, .ORG.DO, .NET.DO, .EDU.DO, .WEB.DO, .ART.DO, and .SLD.DO. Government and military classifications have additional eligibility requirements. Customers should confirm the exact suffix before registering or transferring a domain.
Second-level .DO labels must be at least two characters and no more than 63 characters. Letters, numbers, and hyphens are allowed, but a hyphen cannot begin or end the label. Before ordering, review the available name through the .DO search and registration area.
The registry requires accurate registrant and contact details. DNS information, including primary and secondary nameservers, may also be required as part of the registration setup. Keep your domain information updated through your NiceNIC account after registration.
The registrant provides the new registrar with the domain and authorization code obtained from the current registrar. Before starting a domain transfer request, confirm that the domain is eligible and that the required transfer information is available.
NIC.DO describes a renewal grace period in suspended status, followed by a pending-deletion or redemption period before the domain is released. Renew domains on time through your account to avoid service interruption.
