Chapter 13: Domains, DNS, and Network Access
Introduction
Xiaoming's app was finally deployed successfully.
He eagerly shared the default link assigned by EdgeOne Pages in the group chat: "Come check out the website I built!"
Three minutes later, a friend replied with a screenshot: 403 Forbidden.
Xiaoming panicked — "But my deployment succeeded!" He kept refreshing the page on his own end, and everything looked fine. But his friend still couldn't open it.
The veteran took one look at the screenshot and smiled: "Don't panic. A 403 means 'the door is closed, and you don't have the key.' Default links on domestic platforms often have access restrictions, so only you can view them. If you want other people to access it too, you need to bind a domain name of your own."
"A domain name? You mean that .com thing?"
"Exactly. A domain name is like the internet's contact list — when you search for 'Mom' in your contacts, your phone dials the number for you. When a browser looks up myapp.com, DNS helps it find the server. Right now you're using the platform's temporary number, so other people can't look you up. You need to register a proper number and put it in the contact list."
Xiaoming remembered seeing free subdomains online — the kind like yourname.someone-else-domain.com, hanging under someone else's domain. The veteran stopped him seriously: "That's like borrowing someone else's street address — the landlord can kick you out at any time. If you're building a real product, your domain is part of your storefront. Spending a few dozen yuan on a proper .com is absolutely worth it."
In this chapter, Xiaoming is going to give his website a real, official name.
