strip-dns64 is a DNS forwarder which removes synthesized AAAA answers from
upstream DNS64 servers, implemented initially in Python and then Go for improved
performance

podman build -t strip-dns64 .

podman run -d \
    --name strip-dns64 \
    --network host \
    -e UPSTREAM_DNS="[2001:4860:4860::8888]:53" \
    -e LISTEN_ADDRS="127.0.0.1:53,[::]:53" \
    strip-dns64

podman run -d \
    --name strip-dns64 \
    --cap-add=NET_BIND_SERVICE \
