VIP Response on port UDP 53

Hi,

 

 

we have a virtual server configured that is load balancing traffic on DNZ, udp port 53.

 

 

There 4 DIPs behind this Virtual server.

 

 

I want to check if DIPs are responding when traffic hits the VIP. I can see as below:

 

 

208.94.224.112:mediaspace 7.4.1.59:domain 10.21.200.24:domain udp 1/1 208.94.224.121:15052 7.4.1.59:domain 10.21.200.24:domain udp 1/1 208.94.224.124:19948 7.4.1.59:domain 10.21.200.24:domain udp 1/1

 

 

 

How i can check responses from the DIPs with or without using tcpdump command.
