What is Domain Name Resolution
Introduction
When using the Internet most people connect to web sites, ftp
servers or other Internet servers by connecting to a domain name, as in www.bleepingcomputer.com.
Internet applications, though, do not communicate via domain names, but rather
using IP addresses, such as 192.168.1.1. Therefore when you type a domain
name in your program that you wish to connect to, your application must first
convert it to an IP address that it will use to connect to.
The way these hostnames are resolved to their mapped IP address
is called Domain Name Resolution. On almost all operating systems whether
they be Apple, Linux, Unix, Netware, or Windows the majority of resolutions
from domain names to IP addresses are done through a procedure called DNS.
