I just did tcpdump -i tun0 'udp and port domain'
notebook2# tcpdump -i tun0 'udp and port domain'
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on tun0, link-type NULL (BSD loopback), capture size 96 bytes

I see that the domain names are A and AAAA ? I have seen this
before, when I am at the WiFi cafe. How could this be?
