| Ausführliche Beschreibung | Net::DNS::Async is a fire-and-forget asynchronous DNS helper.
That is, the user application adds DNS questions to the helper, and
the callback will be called at some point in the future without
further intervention from the user application. The application need
not handle selects, timeouts, waiting for a response or any other
such issues.
.
If the same query is added to the queue more than once, the module
may combine the queries; that is, it will perform the query only
once, and will call each callback registered for that query in turn,
passing the same Net::DNS::Response object to each query. For this
reason, you should not modify the Net::DNS::Response object in any
way lest you break things horribly for a subsequent callback.
.
This module is similar in principle to POE::Component::Client::DNS, but
does not require POE.
