That is how a network works. Mail servers and so on are just different types of houses. If you want mail you connect the the telephone number of the ‘mail’ house and so one.

Everything on the internet has to have a Public IP address that is published allowing computers to see it and connect to it. Private are the ones you use in the house. Statis IP’s never change and Dynamic may change everytime you turn on your computer or connect to the internet.
