Zone Files
A zone file is a computer file in ASCII text format that contains all resource records for a given domain. Below is a copy of a standard Internet domain for InetDaemon.com:
inetdaemon.com. IN SOA ns1.hostsave.com. contact.hostsave.com. ( 2001121123 ; serial 102000 ; refres 108000 ; retry 102000 ; expiry 3600 ); minimum inetdaemon.com. IN NS 1.hostsave.com. inetdaemon.com. IN NS 2.hostsave.com. inetdaemon.com. IN NS 3.hostsave.com. inetdaemon.com. IN A 207.150.192.12 inetdaemon.com. IN MX 20 mail.hostsave.com. inetdaemon.com. IN MX 1 mail-incoming.hostsave.com. inetdaemon.com. IN MX 10 mail-incoming2.hostsave.com.
Note that for the domain InetDaemon.Com, the Primary Authoritative Nameserver is named in the SOA record as ns1.hostsave.com. Then below are the settings for how often the secondary server should pull the file and wait between checks, as well as how long information should be cached on any recursive servers that cached an answer they looked up on ns1.hostsave.com.
Note that the 'A' records for the MX and NS records in this domain are located in the 'hostsave.com' zone file, and should NOT be configured in the inetdaemon.com zone file.
