What WHOIS tells you
Every domain name is registered through a registrar, and the registry for its ending keeps a public record: when it was registered, when it expires, which company manages it and which name servers answer for it. That record is what people call WHOIS. Today most registries publish it through RDAP, a newer, structured version, which this tool reads first.
Common uses
- Domain age: an older domain can signal an established business; a days-old domain sending you “urgent” emails is a warning sign.
- Expiry date: make sure your own domains renew in time — an expired domain takes your website and email down with it.
- Registrar: find out where a domain is managed when you need to move it or change its DNS.
- Status codes: “transfer lock” is normal protection; “on hold” or “redemption period” mean the domain is not working.
How to look up a domain
- Type the domain, with or without www — the registered part is found automatically, so shop.example.com.bd looks up example.com.bd.
- Read the summary, and open “Full record” for every detail the registry publishes.
Good to know
- Since GDPR, owner names, emails and addresses are hidden for most domains. To contact an owner, registrars offer a contact form or a relay address.
- Some country endings, such as .bd, have no public WHOIS service. For those, the tool still shows whether the domain exists and its name servers.
Frequently asked questions
How can I find out how old a domain is?
Enter it above. “Registered on” shows the creation date and the domain’s age.
Can I see who owns a domain?
Often not by name, because privacy protection is standard. You can see the registrar and contact the owner through it.
What happens when a domain expires?
It usually stops working within days. Most endings then have a grace and redemption period of about 30–75 days when the owner can still renew it, before it is released for anyone to register.
