hi,
I am setting my own internet DNS server in CentOS 7 currently in non production environment for test purpose.
My Local DNS server IP is 10.1.83.10 and this server is connected with the ISP DNS .
For test point of view I only check it on my one client machine whoes IP address is 10.1.83.250. In the client side I give IP address of my local DNS server in "Local Area Connection" which is 10.1.83.10 and it fetch the webpages as well.
My windows xp computer which is running
Code:
IP Address:10.1.83.250
255.255.255.0
Gateway 10.1.83.1
DNS 10.1.83.10
When I use nklookup command it show me server "Unknown"
Athe server side I also use
Code:
Edit /etc/sysconfig/named and set:
OPTIONS="-4"
When I run the command
Code:
# systemctl status named
I can also see IPV6 showing there.In my cause I am using only IPV4.
I am attaching the snaps here with.
Note: The file named1 and named2 are actually one file. Becuase it was not possible to take the screen short of the complete file that is why i take two screen shorts of it.
My dig command
Code:
[root@masterdns named]# dig -x 10.1.83.250
; <<>> DiG 9.9.4-RedHat-9.9.4-29.el7_2.1 <<>> -x 10.1.83.250
