Frequently asked questions

What is WHOIS?

WHOIS is a public directory that answers "who is responsible for this?" for domains, IP ranges and ASNs. It lists registration dates, the registrar, nameservers and contacts.

What is RDAP, and how does it differ?

RDAP is the modern replacement for WHOIS. It returns the same records in a structured, consistent format. We query RDAP first and fall back to classic WHOIS text when a registry has not adopted it yet.

What is the difference between a registrar and a registrant?

The registrar is the company you register and manage a domain through, such as xTom or GoDaddy. The registrant is the person or organization that actually holds the domain.

What are nameservers?

Nameservers answer DNS questions for a domain and decide which IP addresses the name resolves to. They also show which DNS provider the domain uses.

What is DNSSEC?

DNSSEC adds cryptographic signatures to DNS answers so they cannot be quietly altered in transit. "Signed" means the domain has it enabled, "unsigned" means it does not.

Why is the contact information redacted?

Privacy laws such as GDPR require registrars to hide most personal details in public records. The abuse contact is usually still shown, so a domain or network can be reported when something goes wrong.
