IPv6 only binding in dual stack

[acbekoac]

sudo /opt/dohd/src/dohd -c ${CERT_FILE} -k ${KEY_FILE} -p 443 -d ${IPV4_ADDR} -F -u ${USER}

ss -ltn | fgrep ":443"
LISTEN 0 10 [::]:443 [::]:*

seems IPv6 is preferred (that's ok/great) but as we still need to support IPv4 it would be nice to have the typical "-4" and "-6" switch

seems local problem, using Rocky Linux 8.5 (another VM) I get a

LISTEN 0 10 *:8053 *:*

using
${HOME}/dohd/src/dohd -c ./test.crt -k ./test.key -p 8053 -d 8.8.8.8 -u linux -F
