Editing IPv4 (section)

===Address resolution===
{{Main|Domain Name System}}
Hosts on the [[Internet]] are usually known by names, e.g., www.example.com, not primarily by their IP address, which is used for routing and network interface identification. The use of domain names requires translating, called ''resolving'', them to addresses and vice versa. This is analogous to looking up a phone number in a phone book using the recipient's name.

The translation between addresses and domain names is performed by the [[Domain Name System]] (DNS), a hierarchical, distributed naming system that allows for the subdelegation of [[namespace]]s to other DNS servers.
