When an authoriative DNS server for the recipient's domain receives the query from the sender's DNS server it sends back the IP addresses from the MX dns server in linux it has in that domain's zone file.

It's a way to have the same physical server respond to two different hostnames. Suppose you name your Web server 'debian' instead of 'www'. There can multiples of all of the above record types.

Several important points to note about the records in a zone file: Records dns server in linux specify servers in other domains. This is most commonly used with MX and NS records when backup servers are located in a different domain but receive mail or resolve queries for your domain.

The lines are spaced apart only to aid in the readability of this example. You don't want any blank lines in a zone file.

The first two records in the group of four use A records to specify the servers, and then the second two records are dns server in linux which specify what those servers are used for. The first record in the subgroup of two is a shorthand way of entering the information without the FQDN.


The second record is the longhand way. The ' ' is a shorthand way of specifying "this zone" this domain.
