Since there is no one-to-one relationship between symbolic names
and numerical addresses, both forms will be needed. One name can
resolve to multiple addresses, and one address can have multiple
names.

In addition, access controls based on third-party information from
the DNS will always be less secure than access control based on
numerical addresses only. So, for some purposes the numerical
address form is preferred.
