What is the domain grace period?
The Grace Period is the status that most TLDs enter following expiry.
The Grace Period typically lasts between 0 and 45 days, and often does not have any additional costs associated with it allowing a domain name to still be renewed at the regular rate.
What is the domain redemption grace period?
Redemption is the status that most TLDs enter if they are not renewed during the grace period.
Redemption is a status employed by the registries following the grace period and coincides with a domain being put up for auction. Typically the redemption period will last for 30 days.
Domains can still be renewed while in the redemption status (providing it hasn't been auctioned off) by paying a redemption fee plus the regular renewal cost for the domain.
If the domain is not recovered from redemption, it enters a Pending Delete stage at the Registry for 1-5 days. On the 6th day, the domain is typically released to the public for re-registration.
