Frequently asked questions

What is the difference between a gTLD and a ccTLD?
gTLDs are generic top-level domains, while ccTLDs are assigned to countries or territories. Eligibility rules differ per TLD.
What does DNSSEC support mean?
The TLD supports DNSSEC signatures, but DNSSEC must also be enabled for each individual domain.
Is this information up to date?
TLD and registry information is sourced from public data such as IANA. Eligibility rules can change, so please also check each registry's official information for the latest details.
