Stub Resolver

Dnspython’s resolver module implements a “stub resolver”, which does DNS recursion with the aid of a remote “full resolver” provided by an ISP or other service provider. By default, dnspython will use the full resolver specified by its host system, but another resolver can easily be used simply by setting the nameservers attribute.
