How to use the whois lookup
- Enter a domain such as example.com, or paste a full URL; only the hostname is used.
- Read the banner for the registrar and the days until expiry, then the status list for any locks or holds.
- Compare the registry's name servers with the live NS records; they should match once a change has propagated.
- Copy the report to keep a record before a renewal, transfer or dispute.

- Clear message when a domain is not registered or its registry does not offer RDAP
RDAP versus WHOIS
WHOIS is a 1980s text protocol: every registry formats its answer differently, so results had to be scraped and often broke. RDAP returns the same registration data as JSON over HTTPS in one standard structure, and every generic top-level domain registry is required to offer it. VoltKit uses IANA's bootstrap list to find the right RDAP server for each domain ending, then reads the record straight from the registry. Some country-code registries (for example certain .de or .uk services) still offer only their own WHOIS, and the tool says so when that happens.
Why you will not see the owner's name
Since 2018 registries and registrars redact personal registrant data (name, address, e-mail, phone) from public records, and many now publish only the registrar and a contact form. That is a privacy requirement, not a limitation of this tool. What remains public is still useful: the registrar tells you where to go for a transfer or complaint, the dates tell you how established the domain is and when it might lapse, and the status codes tell you whether it is locked or in trouble.
Reading the expiry date
A domain does not vanish the day it expires. It typically enters an auto-renew grace period, then a redemption period in which the owner can still restore it for a fee, then pending delete, after which it is released. The status codes make each stage visible. If you rely on a domain, renew well before the date and turn on auto-renew at the registrar.
