Introduction
DNS is a
crucial element of both Internet and Active Directory communications. All TCP / IP communication is based on IP
addresses. Each computer on a network has at least one network interface, which
is called a host in TCP/IP parlance, and each host has an IP address that is
unique on that network. Every datagram transmitted by a TCP/IP system contains
the IP address of the sending computer and the IP address of the intended
recipient. However, when users access a shared folder on the network or a
website on the Internet, they do so by specifying or selecting a host name, not
an IP address. This is because names are far easier to remember and use than IP
addresses.
