  $ export srch="192.168.1.0"; echo "as of $(date '+%s';):"; for dns in 1.1.1.1 8.8.8.8 76.76.2.0 9.9.9.9 208.67.222.222 185.228.168.9 76.76.19.19 94.140.14.14; do dig @${dns} microsoft.com +short | grep "${srch}" > /dev/null; if [  $? == 0  ]; then echo "${dns} still has ${srch} for microsoft.com"; else echo "${dns} no longer has ${srch} for microsoft.com"; fi; done
