Network DNS server Establishment complete Introduction

Whether on the LAN or the Internet, people also face another confusion: the computer on the network can only identify such as "61.186.250.41" such as digital address, then why when we open the browser, in the address bar input such as "www.popunet.com" After the domain name, you can see the page we need?
