WHOIS Privacy

A service that masks a registrant's personal contact details in public WHOIS or RDAP records.

WHOIS privacy (or privacy protection) is a service offered by most registrars that substitutes a proxy contact — typically the registrar's own address and a forwarding email — for the registrant's real name, address, phone, and email in public WHOIS and RDAP records. Without it, those details are openly queryable, making owners targets for spam, social-engineering attempts, and targeted phishing designed to compromise registrar credentials. GDPR enforcement since 2018 has pushed many registries to redact personal data by default in gTLD WHOIS, but protection varies by TLD and registrar, so explicitly enabling a privacy service remains good practice. It is important to understand what privacy protection does not do: it hides contact details but does not prevent a technically skilled attacker from using DNS enumeration or certificate transparency logs to map a domain's infrastructure.

Author

Fenwei Bian is a software developer in her thirties who spends her working hours in pull requests and her weekends with her hands in soil or sawdust. Years of open source on GitHub taught her that names are interfaces: a good one is clear, honest about what it does, and kind to whoever has to use it next.

She gardens because it rewards patience and punishes wishful thinking, and she does woodwork because a joint either fits or it doesn't. Both habits show up in how she writes about naming — measure twice, check the source, and don't sand over a rough spot and hope no one notices.

For Namefi she writes about how domain markets actually move, the practical trade-offs of tokenizing and flipping names, and picking a domain you'll still be glad you own in twenty years.

Victor Zhou is a technology founder and standards editor focused on digital identity and trust. He founded Namefi, edits Ethereum Improvement Proposals, and previously led smart-contract architecture work at Google Labs.

His work sits at the intersection of naming, ownership, and the systems people use to establish identity online. That perspective makes him especially interested in the way names move between personal meaning, public recognition, and digital infrastructure.

For Namefi, Victor edits and writes about domains as durable digital identity: how names become ownable onchain assets, how tokenization changes custody and trust, and what naming can learn from the systems people use to establish identity online.
