I have Netgear as router, NetGear itself has 18.104.22.168 set as prim dns. Windows is connected to NetGear and Ubuntu is, while I can
nslookup cf16.eu 22.214.171.124
(it goes on UDP/DNS) I get no response when do
dig @126.96.36.199 cf16.eu from Ubuntu. When +tcp flag is added and it goes on TCP/DNS there is a response.
What can be the problem here? I checked that I have always AD Bit flag set in Ubuntu queries, while this is not set on windows, and I cannot see any other differences in packet frames, ANY!. Does dnsmasq which is running on 127.0.1.1 (and it serves well direct requests on UDP) has something to do here?
