DNS Query - reply from unexpected source

I'm not sure why you think that.

 

 

22:45:39.033309 IP 100.100.100.40.39945 > 8.8.4.4.53: 8917+ A? google.com. (27)

 

22:45:39.033315 IP 100.100.100.40.39945 > 8.8.4.4.53: 8917+ A? google.com. (27)

 

22:45:39.123868 IP 8.8.4.4.53 > 100.100.100.40.39945: 8917 1/0/0 A 173.194.41.69 (43)

 

22:45:39.123884 IP 8.8.4.4.25965 > 100.100.100.40.39945: UDP, length 43

 

 

1. (V) Packet exit server source port 39945 and dst 53

 

2. (V) Packet exit F5 with same attribute

 

3. (V) Packet return to F5 with source port 53 and dst port 39945

 

4. (X) Packet return to server with source port 25965 and dst port 39945

 

 

I'm trying to run TCPDUMP again but now i see only the exit (while still same error on the server)

 

 

$ host -t A godaddy.com 8.8.8.8

 

;; reply from unexpected source: 8.8.8.830517, expected 8.8.8.853

btw, I really appreciate your help here.

 

I got this device for testing LB/DNS Cache/DNS Express and i'm way far from it, still stuck on basics. :)
