msys.cidr.query — Look up address against the named CIDR
name: string address: string, optional
This function looks up addresses against the named CIDR. When using the
rbldnsd types, the return value will always be a string, and will either be the value of the
value_column or the
txt entry. If an entry is not found, this function returns the default_value associated with the CIDR, which is typically
false. If the address is unspecified, the IP address of the connected peer is assumed.
