DNS Record

[Merna]

DNS records are stored in zone files and are used for translating domain names to IP addresses. They also contain other data, including the domain names name server and mail server information. If there are domain name aliases, such as the commonly used www preceding the domain name, these will also be listed in the DNS record.
A typical DNS record may look something like this:
;   Nameservers ;      IN   NS   ns1.4servers.com.   ; 123.456.789.01      IN   NS   ns2.4servers.com.   ; 123.456.789.02 ; ;   Domain Mail Handlers ; yourdomain.com.     IN   MX   0   mail yourdomain.com.     IN   MX  10   mail ; ; ;   hosts in order ; yourdomain.    IN   A   Your.IP.XXX www            IN   A   Your.IP.XXX smtp           IN   CNAME   www pop            IN   CNAME   www ftp            IN   CNAME   www mail           IN   A   Your.IP.XXX ; ; end
Since DNS records are made up entirely of text, they are easy to modify when needed. However, one small typo could redirect a domain name to the wrong Web server or prevent it from showing up at all. This is why it is important to enter DNS information accurately and double-check your changes entry before saving the zone file.
