Entry function
The Scriptable DNS pipeline executes through a statically defined function handleQuery.
To return a response to the query, you can return one of the DNS response objects as documented in the Query Response Object Types.
export default function handleQuery(query) {
return new ARecord("111.111.111.111", 30);
}
console.log is intended for use within the Script Editor only. Please remove
all logging statements before saving or publishing, as they may cause your
script to fail at runtime.
