Sometimes it is useful to be able to access a server (or any host) by using a name other than its DNS host name. For example, you have an Application Server whose DNS confi…guration is as follows:. Host Name Domain Name. --------- -------------. myserver mydomain.com. You have also setup your server as a WWW server so Internet or Intranet browsers can access Web pages from it. You want people to access your Web server by specifying www.mydomain.com as its name instead of myserver.mydomain.com. To accomplish this, an alias (or canonical name) record needs to be added to your DNS server. The DNS server should already have the following record under the mydomain.com zone (IPAddress should be the IP address of your server):. Myserver A . The following record should be added to the mydomain.com zone:. www CNAME myserver.mydomain.com. When a DNS server looks up a name and finds a "CNAME" record, it replaces the name with the canonical name, and looks up the new name, in this case, www.mydomain.com.
used by the server to resolve names
The clear advantage of DNS is that it makes it easy for us to remember the names of websites by converting or displaying the IP addresses(that are in numbers) in understandabl…e names.

DNS translates a domain name into an access IP. Every website is hosted on an IP, the DNS servers tell your computer where a particular domain is hosted.
SOA Resource Records Every zone contains a Start of Authority (SOA) resource record at the beginning of the zone. SOA resource records include the following fields: * … The Owner , TTL , Class , and Type fields, as described in "Resource Record Format" earlier in this chapter. * The authoritative server field shows the primary DNS server authoritative for the zone. * The responsible person field shows the e-mail address of the administrator responsible for the zone. It uses a period (.) instead of an at symbol (@). * The serial number field shows how many times the zone has been updated. When a zone's secondary server contacts the master server for that zone to determine whether it needs to initiate a zone transfer, the zone's secondary server compares its own serial number with that of the master. If the serial number of the master is higher, the secondary server initiates a zone transfer. * The refresh field shows how often the secondary server for the zone checks to see whether the zone has been changed. * The retry field shows how long after sending a zone transfer request the secondary server for the zone waits for a response from the master server before retrying. * The expire field shows how long after the previous zone transfer the secondary server for the zone continues to respond to queries for the zone before discarding its own zone as invalid. * The minimum TTL field applies to all the resource records in the zone whenever a time to live value is not specified in a resource record. Whenever a resolver queries the server, the server sends back resource records along with the minimum time to live. Negative responses are cached for the minimum TTL of the SOA resource record of the authoritative zone.
