Check Domain WHOIS Information Free
Before buying a domain or troubleshooting DNS, WHOIS/RDAP tells you who registered it, when it expires, and which nameservers point where.
What you'll see
- Registrar and registration dates
- Expiry date (renew before this!)
- Nameserver hostnames
- DNS records (A, MX, TXT) when available
- SSL certificate status
Privacy protection
Many domains use WHOIS privacy — registrant details show a proxy service instead of the owner. Expiry and nameservers are still visible.
