Translates domain names to IP addresses. DNS stands for Domain Name System.

From Wikipedia:

The Domain Name System (DNS) is a hierarchical naming system built on a distributed database for computers, services, or any resource connected to the Internet or a private network. It translates domain names meaningful to humans into the numerical identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide.

In addition, since there is no currently no way to authenticate that the reply is really from the DNS server that was queried, there is a proposal (DNSSEC) that will add support for cryptographic signing to all DNS requests (for validation purposes, the data itself would not be encrypted).

In Mac OS X, how do I check what DNS server I'm currently using (preferably a command line solution)? System Preferences > Network shows 192.168.1.1, which is my router's address and not the real DNS server.

In /etc/resolv.conf, what exactly does the "search" configuration option do?

If I have the option set as the domain name of the server itself, does that mean the server itself is used first to lookup domain names before querying the external internet? i.e. /etc/hosts will be queried? For example: search example.com
