DNS server Configuration

Guide

DNS (domain name server, nameservers) is the server that is transforming the domain name and the corresponding IP address. DNS holds a domain name and the corresponding IP address (IP addresses) table to resolve the domain name of the message. Let me give you a brief look at the configuration of the DNS server.

Master File Configuration

Define the DNS master file/etc/named.rfc1912.zones, and add the following lines later:

Zone "supsun.com" in{    type master;    File "Supsun.com.zone";    Allow-update{none;};}; Zone "6.1.10.in-addr.arpa" in{    type master;    File "Supsun.com.local";    allow-update{none};};
