					Review DNS

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. Most importantly,
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.

An often-used analogy to explain the Domain Name System is that it serves as the "phone book" for the
Internet by translating human-friendly computer hostnames into IP addresses. For example, the domain
name www.example.com translates to the addresses 192.0.32.10 (IPv4) and 2620:0:2d0:200::10 (IPv6).

The Domain Name System makes it possible to assign domain names to groups of Internet resources
and users in a meaningful way, independent of each entity's physical location. Because of this, World
Wide Web (WWW) hyperlinks and Internet contact information can remain consistent and constant
even if the current Internet routing arrangements change or the participant uses a mobile device.
Internet domain names are easier to remember than IP addresses such as 208.77.188.166 (IPv4) or
2001:db8:1f70::999:de8:7648:6e8 (IPv6). Users take advantage of this when they recite meaningful
Uniform Resource Locators (URLs) and e-mail addresses without having to know how the computer
actually locates them.

The Domain Name System distributes the responsibility of assigning domain names and mapping those
names to IP addresses by designating authoritative name servers for each domain. Authoritative name
servers are assigned to be responsible for their particular domains, and in turn can assign other
authoritative name servers for their sub-domains. This mechanism has made the DNS distributed and
fault tolerant and has helped avoid the need for a single central register to be continually consulted and
updated.

In general, the Domain Name System also stores other types of information, such as the list of mail
servers that accept email for a given Internet domain. By providing a worldwide, distributed keyword-
based redirection service, the Domain Name System is an essential component of the functionality of
the Internet.

Other identifiers such as RFID tags, UPCs, International characters in email addresses and host names,
and a variety of other identifiers could all potentially use DNS.

The Domain Name System also specifies the technical functionality of this database service. It defines
the DNS protocol, a detailed definition of the data structures and communication exchanges used in
DNS, as part of the Internet Protocol Suite.

Ok let’s begin to create…………….

    1.   Put one of server, hub, and pc client
    2.   For connections use straight cable from server to hub and same for client use straight too
    3.   Now set up server dhcp same as existing posts
    4.   Now how to set up DNS server
