Abstract
Asynchronous techniques are provided for resolving domain names and for automated classification of domain type. An exemplary method comprises asynchronously resolving at least two known domains in parallel to obtain a current domain-to-IP address resolution for the at least two known domains, wherein a schedule of the asynchronous resolution is based on a Time-To-Live attribute of a latest domain-to-IP address resolution of the at least two known domains; determining if the current domain-to-IP address resolution matches the latest domain-to-IP address for the at least two known domains; and updating the domain-to-IP address table with the current domain-to-IP address resolution and corresponding resolution time if the current domain-to-IP address resolution does not match the latest domain-to-IP address for a given known domain. In one or more embodiments, a Time-To-Live attribute of the current domain-to-IP address resolution for the given known domain is updated in the domain table. A plurality of worker processes optionally perform the asynchronous resolution.
