I used a capture filter with tcpdump with only the hosts rather than “port 53” or the like to omit this reported filter issue in which IP fragments were not captured.) And since “host” queries A/AAAA/MX records for each FQDN, there are even more queries in the final trace. I end up with 71 queries for each Internet Protocol, that is, 142 queries in total.I did not specify whether UDP or TCP shall be used.How can I look at the DNS queries all sent in the capture time So for any given website, I need to find the. For some reason, I had problems querying Quad9 for “RRSIG” resource records.ĭig rrsig let to SERVFAIL responses in some situations, while others worked. And go to a website for about 20 seconds.I was using the recursive DNS servers from Quad9, for IPv6 (2620:fe::fe) as well as for legacy IP (9.9.9.9).This should give a wide range of different DNS packets in the trace file. This filter removes all packets that neither originate nor are. Since I am generally more interested in IPv6 rather than legacy IP, I issued all queries via IPv6 and IPv4. addr yourIPaddress into the filter, where you obtain yourIPaddress with ipconfig. ![]() Anyway, I let those falsified connections in the trace as well. Now, let’s create some filters Move the conversations screen to the side, and have the main Wireshark screen on another side. So probably due to the 6in4 tunnel broker?) Wireshark shows some “malformed DNS” packets. Probably due to my intermediate firewall (Palo Alto Networks) or the used IPv6 Tunnel Broker?!? (I have looked up the counters on Palo Alto, but no drops. Host 2620:fe::fe was not working error message “ connection timed out no servers could be reached”.
