这个是什么意思啊？是什么状态？能不能详细解释一下？
还有就是会有“ok”这样的状态，这是什么意思？是什么状态？和active状态有什么区别？能不能详细解释一下？

Answer 1

Domain Status: clientTransferProhibited 域名禁止转让
Domain Status: clientDeleteProhibited 域名禁止删除
Domain Status: clientUpdateProhibited 域名禁止更新

ACTIVE: The registry sets this status. The domain can be modified by the registrar. The domain can be renewed. The domain will be included in the zone if the domain has been delegated to at least one name server.
（激活状态）

REGISTRY-LOCK: The registry sets this status. The domain can not be modified or deleted by the registrar. The registry must remove the REGISTRY-LOCK status for the registrar to modify the domain. The domain can be renewed. The domain will be included in the zone if the domain has been delegated to at least one name server.

REGISTRAR-LOCK: The sponsoring registrar sets this status. The domain can not be modified or deleted. The registrar must remove REGISTRAR-LOCK status to modify the domain. The domain can be renewed. The domain will be included in the zone.
（注册商锁定）

REGISTRY-HOLD: The registry sets this status. The domain can not be modified or deleted by the registrar. The registry must remove the REGISTRY-HOLD status for the registrar to modify the domain. The domain can be renewed. The domain will not be included in the zone.

REGISTRAR-HOLD: The sponsoring registrar sets this status. The domain can not be modified or deleted. The registrar must remove REGISTRAR-HOLD status to modify the domain. The domain can be renewed. The domain will not be included in the zone.
（注册商保留）

REDEMPTIONPERIOD: The registry sets this status when a registrar requests that the domain name be deleted from the registry and the domain has been registered for more than 5 calendar days (if the delete request is received within 5 days of initial domain registration it will instead be deleted immediately). The domain will not be included in the zone. The domain can not be modified or purged; it can only be restored. Any other registrar requests to modify or otherwise update the domain will be rejected. The domain will be held in this status for a maximum of 30 calendar days.

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 otherwise 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. If the registrar fails to provide documentation to the registry within 7 calendar days to confirm the restoration request, the domain will revert to REDEMPTIONPERIOD status. 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 registry sets this status after a domain has been set in REDEMPTIONPERIOD status and the domain has not been restored by the registrar. 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. The domain will be purged from the registry database after being in this status for 5 calendar days.

Answer 2

whois（读作“Who is”，非缩写）是用来查询域名的IP以及所有者等信息的传输协议。简单说，whois就是一个用来查询域名是否已经被注册，以及注册域名的详细信息的数据库（如域名所有人、域名注册商）。通过whois来实现对域名信息的查询。早期的whois查询多以命令列接口存在，但是现在出现了一些网页接口简化的线上查询工具，可以一次向不同的数据库查询。网页接口的查询工具仍然依赖whois协议向服务器发送查询请求，命令列接口的工具仍然被系统管理员广泛使用。whois通常使用TCP协议43端口。每个域名/IP的whois信息由对应的管理机构保存。
域名注册成功后，一般分为以下几种状态：（“Status”后面所连接的文字）
ACTIVE：表示域名状态正常，在域名注册商的whois中可域名的详细信息，可以续费。
REGISTRAR-LOCK：表示域名被注册商锁定，此时域名不能进行转移，可以续费。
REGISTRAR-HOLD：表示域名被注册商保留，此时域名已到期，不能进行转移，可以续费。
REDEMPTIONPERIOD：表示域名处在赎回期（为期30天），不能续费，只能高价赎回。
PENDINGDELETE：表示域名处在删除期（为期5天左右），不能赎回。
