Just be warned that this won't work with some DNS servers, since the DNS
protocol requires that you try UDP first and only fall back to TCP if the
server returns a truncated response. Some DNS servers that already know
that their entire response database fits into UDP packets will therefore
choose not to listen or respond to TCP connections at all (since DNS over
TCP is a widely used attack target for bugs in BIND).
Might be worth a note in the manual about that.
