[bert hubert]

These are all acl drops. Ponder using setting an acl with setACL()!

A different query type and target can be specified by passing, respectively, the 'checkType' and 'checkName' parameters tonewServer. The default behavior is to consider any valid response with a RCODE different from ServFail as valid. If the 'mustResolve' parameter of newServer is set to true, a response will only be considered valid if its RCODE differs from NXDomain, ServFail and Refused."
