"There are many architectural assumptions regarding DNS behavior
that are not specified in the IETF standards documents describing
DNS, but which are deeply embedded in the behavior of Internet
protocols and applications. These assumptions are inherent parts of
the network architecture of which the DNS is one component.
It has long been known that it is possible to use DNS wildcards in
ways that violate these assumptions.
Recent deployments of DNS wildcards with A records at high levels in
the DNS tree have shown by experience that the cost of violating
these assumptions is significant.
