►If you need to set www.netc.tw, please enter www in "Hostname/cname"

►If you need to set netc.tw, please do not enter any word in "Hostname/cname"

►If you need to set both www.netc.tw and netc.tw, please set two A records.

►For example :
mail.netc.tw
dns.netc.tw

• If you need to set sub domain without IP address, please refer "Cname record"
