.dds is a generic top-level domain listed by IANA. Its IANA-designated manager is Registry Services, LLC.
Search a specific .dds name to check availability and use the technical page for documented eligibility rules. A seller’s standard price does not decide whether an applicant or a particular name qualifies.
Compare registration, renewal and transfer separately when seller observations are available. A standard tariff does not include a premium-domain quote or confirm that a specific name is available.
The registry policy records a minimum registration term of 1 year. Seller checkout terms can be longer, so use the displayed coverage beside each price.
The registry policy records individual-domain DNSSEC support for .dds. Your registrar must still provide the needed DS-record or signing workflow.
