hostid	String	Domain name ID
hostname	String	Domain name added to cloud WAF.
policyid	String	Policy ID
access_code	String	CNAME prefix
protect_status	Integer	WAF status of the protected domain name. -1: The WAF protection is bypassed. Requests of the domain name are directly sent to the backend server and do not pass through WAF. 0: The WAF protection is suspended. WAF only forwards requests destined for the domain name and does not detect attacks. 1: The WAF protection is enabled. WAF detects attacks based on the policy you configure.
access_status	Integer	Domain name access status. The value can be 0 or 1. 0: The website traffic has not been routed to WAF. 1: The website traffic has been routed to WAF.
proxy	Boolean	Whether a proxy is used for the protected domain name. false: No proxies are used. true: A proxy is used.
timestamp	Long	Time the domain name was added to WAF.
paid_type	String	Package billing mode. The value can be prePaid or postPaid. prePaid is for yearly/monthly billing. postPaid is for pay-per-use billing. Default value: prePaid.
flag	Flag object	Special identifier, which is used on the console.
waf_type	String	Mode of WAF that is used to protection the domain name. The value can be cloud or premium. cloud: The cloud WAF is used to protect the domain. premium: A dedicated WAF instance is used to protect the domain name.
web_tag	String	Website name, which is the same as the website name in the domain name details on the WAF console.
access_progress	Array of Access_progress objects	Access progress, which is used only for the new WAF console.
premium_waf_instances	Array of Premium_waf_instances objects	List of dedicated WAF instances
description	String	Domain name description
exclusive_ip	Boolean	Whether to use a dedicated IP address. This parameter is reserved and can be ignored. true: Use a dedicated IP address. false: Do not use a dedicated IP address.
region	String	Region ID. This parameter is included when the domain name was added to WAF through the console. This parameter is left blank when the domain name was added to WAF by calling an API. You can query the region ID on the Regions and Endpoints page on the Huawei Cloud website.
server	Array of WafServer objects	Origin server settings of the protected domain name. The value of vpc_id is returned only for domain names protected with dedicated instances.

**Table 5** Flag
Parameter	Type	Description
pci_3ds	String	Whether the website passes the PCI 3DS certification check. true: The website passed the PCI 3DS certification check. false: The website failed the PCI 3DS certification check.
pci_dss	String	Whether the website passed the PCI DSS certification check. true: The website passed the PCI DSS certification check. false: The website failed the PCI DSS certification check.
cname	String	The CNAME record being used. old: The old CNAME record is used. new: The new CNAME record is used.
is_dual_az	String	Whether WAF support Multi-AZ DR true: WAF supports multi-AZ DR. false: WAF does not support multi-AZ DR.
ipv6	String	Whether IPv6 protection is supported. true: IPv6 protection is supported. false: IPv6 protection is not supported.

**Table 6** Access_progress
Parameter	Type	Description
step	Integer	Procedure 1: Whitelisting the WAF IP addresses. 2: Testing connectivity. 3: Modifying DNS records.
status	Integer	Status. The value can be 0 or 1. 0: The step has not been finished. 1: The step has finished.

**Table 7** Premium_waf_instances
Parameter	Type	Description
id	String	ID of the dedicated WAF instance.
name	String	Name of the dedicated WAF instance.
accessed	Boolean	Whether the domain name is added to the dedicated WAF instance. The options are true and false. true: The domain name has been added to WAF. false: The domain name has not been added to WAF.

**Table 8** WafServer
Parameter	Type	Description
front_protocol	String	Protocol used by the client to access the origin server of the protected domain name.
back_protocol	String	Protocol used by WAF to forward client requests to the origin server of the protected domain name.
weight	Integer	Weight of the origin server. The load balancing algorithm allocates requests to the origin server based on the weight. The default value is 1. This parameter is not required for WAF cloud mode.
address	String	IP address of origin server accessed by the client
port	Integer	Port used by WAF to forward client requests to the origin server
type	String	Type of the origin server address: IPv4 or IPv6
vpc_id	String	VPC ID. To obtain the VPC ID, perform the following steps: Use either of the following methods to obtain the VPC ID. Log in to the WAF console and choose Instance Management > Dedicated Engine > VPC\Subnet. The VPC ID is in the VPC\Subnet column. Log in to the VPC console and click the VPC name. On the page displayed, copy the ID in the VPC Information area.
