IONOS says its Private Registration/WHOIS Privacy addon is discontinued. Personal data protection differs for individuals and organizations; absence of the addon does not mean all personal data is public. Check current registrant-type requirements.

WHOIS ID Protection is a separately purchased addon under the standard Hostwinds domain policy. Gated WHOIS is distinct from this addon. TLD eligibility still applies.
