Add the below to update every other hour

# m h  dom mon dow   command

#update bi-hourly the DNS (use the FULL path to executables, and leave "ip=" empty so it's auto detected)
18 */2 * * * /usr/bin/curl "https://www.duckdns.org/update?domains=YOURDOMAIN&token=064not40-my4c-real-8to5-2ken452b0c1&ip=" > /tmp/latest_IP_update_result.log 2>&1
