I m newbie in web hosting. can anyone tell me what is DNS ?
DNS can be considered something similar to a phone book. When you move from one location to another, your name stays the same, but your phone number may change. In order to point your name to the new phone number, you must contact the telephone service provider so they assign you the new phone number and update all directory information to reflect you as pointing to this new phone number.
In this way, the IP number can be compared to a phone number: When someone calls http://www.cpwebhosting.net, your ISP looks at the DNS server, and asks “how do I contact example.com?” The DNS server responds: “It can be found at 184.108.40.206”. As the Internet understands it, this can be considered the phone number for the server, which houses the http://www.cpwebhosting.net web site.
The DNS records for your domain are kept on your hosting server in the place called DNS zone. When you register a domain by means of the control panel, all DNS records are automatically created for you, but in some rare cases you may need to add custom records to your DNS zone. An example would be when you want all email to be processed by an external mail server rather than by the built-in mail system. However, such user intervention requires knowledge of DNS configuration and clear understanding of what is to be done.
How Do I Create Custom DNS records?
To create a custom record to your DNS zone, do the following:
1. Select Domain info in the Domain Settings menu.
2. On the page that appears, click the Edit icon in the DNS Configuration field
3. This link will take you to the DNS Configuration page
On this page you can see several blocks of DNS records. Some are built-in and non-removable; others are user-defined and can be deleted. Built-in MX records require special consideration: they can be removed by disabling mailservices for this domain., but all e-mail resources, including mailboxes, forwarders, and autoresponders will also be deleted. The removal of H-Sphere 2.x email services was made possible to enable the use of e-mail services provided by other mail servers.
You can add any type of DNS records by clicking an appropriate link. You will be asked to enter corresponding DNS data.
U can also add Custom A Records
Normally, A records are used to map domain names and web server IP’s.
If you have selected A record, the page appears, which has:
* Name: enter the string to map to the web server.
* TTL: set how many seconds will elapse before the record is refreshed in the DNS cache.
* Data: enter the IP of the web server.
