**Table 2** Parameters in the request
Parameter	Mandatory	Type	Description
name	Yes	String	Fully qualified domain name (FQDN) suffixed with a zone name, which is a complete host name ended with a dot A domain name is case insensitive. Uppercase letters will also be converted into lowercase letters.
description	No	String	(Optional) Description of the domain name, which cannot exceed 255 characters The value is left blank by default.
type	Yes	String	Record set type The value can be A, AAAA, MX, CNAME, TXT, NS, SRV, or CAA. For details, see Record Set Type.
status	No	String	Status of the record set The value can be: ENABLE: The record set will be enabled. DISABLE: The record set will be disabled. If the value is left empty, the status of the record set depends on the status of the domain name: The status of the record set will be set to Enable if the status of the zone is ACTIVE. The status of the record set will be set to Disabled if the status of the zone is Disabled.
ttl	No	Integer	Record set cache duration (in seconds) on a local DNS server. The longer the duration is, the slower the update takes effect. If your service address is frequently changed, set TTL to a smaller value. Value range: Public zone: 1–2147483647 Private zone: 300–2147483647 The default value is 300.
records	No	Array of strings	Value of the record set. The value format varies depending on record set types. For example, the value of an AAAA record set is the IPv6 address list mapped to the domain name. When an alias record is used, this parameter is not required.
line	No	String	Resolution line ID. The default value is the default line.
tags	No	Array of object	Resource tag. For details, see Table 3. The value is left blank by default.
weight	No	Integer	Weight of the record set If this value is left blank, the default value 1 takes effect. If weight is set to 0, the record set is a secondary one. If weight is larger than 0, the record set is a primary one. The value ranges from 0 to 1000. You can create a maximum of 20 record sets with the same name, type, and resolution line but different weight values.
alias_target	No	Object	Domain name alias. For details, see Table 4. The value is left blank by default.

The first and last characters cannot be spaces.
