These are the 8 domain name status codes used for COM and NET domains :

ACTIVE

This is the normal state for a domain name. The domain is functional and can be renewed. Domains that are active can be used for Web sites, for email, or to register name servers. The domain will be included in the zone if the domain has been delegated to at least one name server.
REGISTRAR-HOLD

The domain has been placed on hold by the registrar and cannot be used. The domain can not be modified or deleted. The domain has been expired but can be renewed without a penalty fee. The domain will not be included in the zone.
REGISTRY-HOLD

The domain has been placed on hold by the registry and cannot be used. The domain will not be included in the zone until it’s renewed. REGISTRY HOLD status lasts for a period of 40 calendar days after the day the domain has expired.
REGISTRAR-LOCK

The registrar, often at the request of the domain registrant, has locked down the domain so that its settings cannot be modified. The domain can be renewed. The domain will be included in the zone.
REGISTRY-LOCK

The registry has locked down the domain so that its settings cannot be modified or deleted by the registrar. The domain can be renewed.
RedemptionPeriod

The domain has expired and the registry is waiting for 30 days as a precautionary measure before releasing it. The domain can not be modified or purged; it can only be restored which would require the domain owner to pay a redemption/penalty fee as well as the renewal fee to renew the domain. Any other registrar requests to modify or otherwise update the domain will be rejected.
PendingRestore

The registry sets this status after a registrar requests restoration of a domain that is in REDEMPTIONPERIOD status. The domain will be included in the zone. Registrar requests to modify or update the domain will be rejected.

The domain will be held in this status while the registry waits for the registrar to provide required restoration documentation. The domain status will be set to ACTIVE only if the registrar provides documentation to the registry within 7 calendar days to confirm the restoration request.
PendingDelete

The domain expired 75 days ago and the registry is about to erase it. The registry sets this status after a domain has been set in REDEMPTIONPERIOD status and the domain has not been restored by the registrar. A domain remains in this status for five days before it is deleted. The domain will not be included in the zone.

Once in this status all registrar requests to modify or otherwise update the domain will be rejected. Once purged, the domain will be available to the public for registration.
