You Own a Website — These 3 Things Keep It Working
If you've ever bought a domain, pointed it to a server, or wondered what that padlock icon in the browser means — this article is for you.
We're going to explain domains, DNS, and SSL in plain language. No networking degree required.
Domains — Your Website's Address
A domain is just a name that points to a server on the internet.
When someone types fiznex.com in their browser:
That name is translated into an IP address
The browser connects to the correct server
You don't permanently own a domain — you rent it, usually for 1 year at a time.
Common places to buy domains:
Namecheap
GoDaddy
Google Domains
AWS Route 53
Tips for Choosing a Domain
Keep it short and easy to spell
.com is still the most trusted extension
Avoid hyphens and numbers if possible
Make sure it’s not trademarked
DNS — The Internet's Phone Book
DNS (Domain Name System) connects your domain name to your server's IP address.
Think of it like a phone book:
You search a name
It gives you a number
When you buy a domain, you set up DNS records that tell the internet where your website lives.
Common DNS Records
A Record — Points domain to an IP address
CNAME — Points one domain to another
MX Record — Handles email routing
TXT Record — Verification and security (SPF, DKIM)
When you update DNS, it takes time to spread across the internet. This is called propagation.
Usually takes 15 minutes to 48 hours
If the site doesn’t work immediately, wait
SSL — The Padlock in Your Browser
SSL (technically TLS) encrypts the connection between your visitor’s browser and your server.
When you see:
https://
A padlock icon
That means SSL is active.
Why SSL Matters
Security — Protects passwords and payment details
Trust — Browsers show warnings without it
SEO — HTTPS is a ranking factor
Payments — Required by payment processors
How to Get SSL
Two common options:
Let's Encrypt — Free, automatic, widely used
AWS ACM — Free when using AWS services
There’s no reason to pay for SSL anymore.
Free options are just as secure.
How They All Work Together
Here’s what happens when someone visits your website:
User types fiznex.com
Browser asks DNS for the IP address
DNS returns your server’s IP
Browser connects to the server
SSL encrypts the connection
Server sends the website
User sees your site with a padlock
All of this happens in milliseconds.
Common Issues and How to Fix Them
“This site can’t be reached” — Check your A record
“Not Secure” warning — SSL isn’t set up or expired
Works on www but not without it — Missing A record or CNAME
Email not working after DNS change — Check MX records
What You Should Remember
As a business owner, you don’t need to manage DNS daily.
But you should know the basics:
Know where your domain is registered
Make sure SSL is installed
Keep your domain renewed
These three things prevent 90% of website emergencies.
