All domains have a life cycle. Depending on their extension it can happen that the Redemption period is longer (or shorter) than other extensions.
In this article you can see the different periods that a domain has and you will find a list of the periods for the most common extensions.
Available: As its name says, the domain is still available for registration.
Registered: At the time a free domain is requested, it is assigned to the person who requested it. If everything is correct, the domain is active. The domain will be active during the years for which the registration has been requested. During this period you can extend the number of years to prevent the domain from expiring when it reaches the expiration date. The api call for renewal is renewDomainRequest and you can also renew the domain via your Reseller Control Panel.
Grace period: The domain has expired and stops working. It must be reactivated immediately if the owner of the domain wishes to maintain the domain. For the most common extensions (gTLDs) there is no restore fee, you just pay for the renewal of the domain but for many ccTLDs if the domain is in grace period you have to pay for the restore. The api call for the reactivation is restoreDomainRequest and you can also restore a domain through our Reseller Control Panel.
Redemption Period: The domain has been removed, but can be reactivated and renewed at a higher price than the usual price for a renewal. The api call for the reactivation is restoreDomainRequest.
Pending Delete: The domain will be deleted by the registry and can no longer be reactivated. It will become free for registration.
