Domain Name Service(DNS) is an Internet naming system which resolves host names to IP addresses and IP addresses to host names. We will be creating DNS server, to do so we need to configure ‘named’ and ‘zone’ files.

Things to do
[/symple_box]
- Check for BIND files or install it.
- Create and configure /etc/named.conf.
- Create /var/named and download root server files.
- Configure zone files.
- enable DNS services.
Note: server IP is 192.168.16.128 and DNS server name is data.serv
Steps to configure BIND DNS in Oracle Solaris 10.

Step 2
vi /etc/named.conf #create named.conf file

};
zone “.” {
type hint;
file “db.cache”;
};
#Reverse Zones###
zone “0.0.127.in-addr.arpa” {
type master;
file “db.127.0.0”;
};
zone “16.168.192.in-addr.arpa” {

file “db.192.168.16”;
};
###Forward Zone###
zone “data.serv” {
type master;

Errors may come, you can check errors in /var/adm/messages by default. You can also check for syntax errors using either of these commands:
