BIND Installation On CentOSWhat is bind?BIND is alternative software for translating domain names into IPaddresses. Because domain names are alphabetic, they are easier toremember. So if wewill browse the Internet we don(TM)t need toremember IP addresses. For example, the domain name www.yourdomain.com mighttranslate to 192.168.0.1

.

1. You Can Check BIND Packet

[root@server named]# rpm -qa

bind*

bind-libs-9.2.4-2

bind-utils-9.2.4-2

bind-9.2.4-2

2. Setting Computer NS1 With IP 192.168.0.1 As Nameserver And Domain Name yourdomain.com

[root@server ~]# cat /etc/resolv.conf

nameserver192.168.0.1

3. Setting File /etc/named.conf

[root@server ~]# nano /etc/named.conf
