            NO you did not.. Download the capture and attach the pcap... All you can see there is the dest and source IPs... You can not SEE what was asked and what was returned.. I want the actual pcap so I can load it into wireshark and view what is going on. Also make sure you bump up the 100 packet limit since seems you have other dns queries going on there.

            Also what does the cache show you for unbound... See my other command I posted.

            47.338473 IP f.gtld-servers.net.domain > 88.247.225.172.static.ttnet.com.tr.51526: UDP, length 1048

            Here one of the gtld servers answered you - what did he say? If had the pcap could load into wireshark and SEE exactly what was returned.

                Ok WTF look at this... your asking averyone and their browser for this - and no response!!!

                0_1536956060033_query.png

                Why are you sending queries to ALL these IPs Notse are not the IPs for NS for that domain..

                But you do get a response looking up synology something.

                    So your asking Roots - and NOT getting any answers... I looked up the first 2 there those are root servers... So where are you answers??

                    Ask roots for that A record you should get back the NS for .net

                    Your just asking and asking and asking and not getting back anything... Why? That will explain why you can not resolve for sure.

                            So same thing dude your asking

                            0_1537015197873_noresponse.png

                            But you get NO response?? Something upstream of you filtering dns? There should be no reason that I can think of why if you ask a root server your not getting a response. You can see other queries there where you ask root and get answers..

                            This is what should look like - you ask, and get answer of all the NS for .net

                                198.41.0.4 is root - I just edit in wireshark what my public IP resolves too ;) Not a fan of posting my public IP on forums - especially when I have ticked off a few people here that might do something with that info - hehehe

                                You can install dig on your windows machine.. Just download bind from iSC and say install tools only... I run dig on windows all the time..

                                  I should have known this one human life before. Nuking nslookup from orbit right now.

                                    hehhe - nslookup is a joke of a tool compared to dig..

                                    edit: BTW - newer versions you might have to set resolv.conf pointing to your nameserver in the etc folder it creates if don't want to have to use @ namserver in the cmdline all the time... Unless they fixed that? I think starting with 9.12 it was failing to pull NS from the OS..

                                    let me check

                                    yeah - if you don't have a resolv.conf file in the etc folder dig 9.12.2-p1 atleast does not pull NS its suppose to use..

                                    So create a resolv.conf and put in
                                    namserver ipaddress

                                    That you want to use with dig so you don't have to always call it out.

                                        Run the install - pick tools only..

                                        0_1537017104819_install.png

                                        The only issues is if you don't want to have to tell dig which NS to use every time you run it - then you need to create a resolv.conf file in the etc folder it creates when you install it..

                                        0_1537017266020_resolvfile.png

                                        Put in nameserver you want it to use.. then when you run dig it will default to using that ns..

                                          @johnpoz hehe. Damn TTNET they are modifying our dnses.
                                          Yeah the first dig command with TTNET nameserver(Office ISP)
                                          Second one is taken with KABLONET nameservers(Home ISP)

                                          And both of tested from home In KABLONET I cannot resolve hostname with TTNET dnses. But I can resolve it with default KABLONET dnses.

                                          I dont know how to capture packets without pfsense. If you know tell me pls. I can send capture from house network too. Maybe it can help.
