comment Force forwarder DNS requests to TCP mode
Actaully host uses the standard resolver library, and on my workstation it supports EDNS0. To test if the requests specifies EDNS0, run 'tcpdump -x port 53' and the hex dump should contain (towards the end, in the additional section) the sequence 0029 1000 0000 8000 0000, which is the binary representation of the OPT RR.
