How do your Machine actually access the server for the WEB and e-mail that you casually use?

For example, You will try to access the homepage https://www.MyDNS.JP/. Your machine makes a request to DNS. "Please tell me the IP address of www.mydns.jp."

DNS looks up the upper DNS from the domain. Eventually, you will find the primary name server for that domain... DNS replied. "That is 210.197.74.200."

Dynamic DNS can change this IP address at any time and immediately! But, Please be regularly notifie!
