A DNS record is the smallest instance containing the exact information that indicates which domain name “belongs” to which destination address. For Hostpoint, for example, the DNS must include the information that ‘hostpoint.ch’ must resolve to the IP address ‘220.127.116.11’.
You can think of this as a simple text record in a file or database.
However, the record includes additional information:
|Host name||TTL (Time to Live)||Class Internet)||Type||Destination|
There are, of course, other types of DNS records. Here is a list of the most common ones:
|SOA||Start of Authority||ns.hostpoint.ch. hostmaster.hostpoint.ch. 20130614 86400 7200 3628800 12096000|
|NS||Authoritative Nameserver of the domain||ns.hostpoint.ch|
|A||IPv4 address of the domain||18.104.22.168|
|CNAME||Canonical name of the domain||Host|
|MX||Mail-Exchange, the mail server used for your domain||mx1.mail.hostpoint.ch |
