			The mappings are obviously an [[attack surface]] for someone wishing to do harm.

The key for the top level is widely publicized by 'out of band' means.

The '''Domain Name System''' (usually abbreviated to '''DNS''') is a [[distributed database]] which is used on the [[Internet]] to hold [[mapping]]s from human-readable names (such as '.COM') to [[binary]] [[address]]es.

The DNS is organized as a [[hierarchy]]; like [[file]] names in a hierarchical [[file system]], a complete DNS name consists of a number of parts, each one of which selects one of the possibile [[namespace]]s (sub-directories) at the next level down. The leaves of the tree usually name individual [[host]]s.

Although the DNS has the capability to hold addresses for a number of different [[protocol suite]]s, in general it now only hold addresses for the [[Internet Protocol]].
