Domains on the internet have a life cycle, where the domain is initially available to the public, owned by someone or may even be available again because the owner does not renew the domain.
the following is a table of how the domain cycles:

status description
Available Domains In this status the domain is still available to the public, it can still be registered by anyone who wants to register a domain, who can get the domain first.
Registered The domain is already owned by someone, according to the purchase period. as long as the Domain is extended, it will still belong to that party, but if the domain is not renewed, it will automatically go to the next stage.
Expired
40 Days
Domain Expired Status is the domain has been suspended, this is because it was not renewed by the domain owner. Expired domains can still be renewed at normal prices, if the owner renews the domain, it will automatically become active again.
