Parameter	Description	Value
host-text	Specifies a domain name rule.	The value is a string of 4 to 255 characters and cannot contain slashes (/), backslashes (\), number signs (#), double quotation marks ("), or question marks (?). The asterisk () can appear at the beginning, middle, or end of a domain name rule: When it appears at the beginning, it is a wildcard character that indicates suffix matching, such as abc. When it appears in the middle, it is a common character, such as *abc*. When it appears at the end, it is a wildcard character that indicates prefix matching, such as abc. When it appears at both the beginning and the end, it is a wildcard character and indicates keyword matching, such as *abc. If a domain name rule contains a wildcard character, it must contain at least three consecutive characters except the wildcard character, such as abc, *abc, ab, and ab. If a domain name rule does not contain any wildcard character, the domain name is matched in exact matching mode. In this case, the domain name rule must contain at least four consecutive characters, such as abcd*.
all	Indicates all domain name rules.	-
