Hi,

it displays (www.google.co.in <http://www.google.co.in>) URL link IP. Instead of this I want to filter only DNS. 192.168.16.67 <http://192.168.16.67/> and 192.168.16.106 <http://192.168.16.106/>. client IP) (DNS server IP)
I had attached the sample excel file for your reference.

for this what kind of filters should I use in my command.

With a filter of just "dns" Wireshark will show you all the DNS queries it sees.

If you want only DNS to/from the specific IP addresses listed, you could do:

dns && ip.addr == 192.168.16.67 && ip.addr == 192.168.16.106

for example.

If you want only DNS from a specific IP to a specific IP you could do:

dns && ip.src == 192.168.16.67 && ip.dest == 192.168.16.106
