Domain basics
What is a domain name?
A domain name is the readable name people use to reach an Internet service, such as example.com. DNS connects that name to the technical records used by websites, email and other services.

The core concept
A domain is a name inside a hierarchy
Dots separate levels. Read from right to left to move from the broad namespace toward the specific host.

comTop-level domain
Most people use “domain name” to mean the registrable combination example.com, while shop.example.com is a host beneath it.
The essentials
Registered, not purchased forever
A registration gives the holder renewable rights under the registry and registrar terms.
renew each registration term
Useful beyond websites
The same domain can identify web pages, email addresses and other Internet services.
www · mail · api
Connected by DNS
DNS records tell software which systems handle the services attached to the name.
A · AAAA · MX · TXT
From an idea to a working domain
Registration reserves the name. DNS configuration makes it useful.
Choose the complete name
Select both the label and extension, then check availability and conflicts.
Register through a registrar
The registrar submits the registration to the registry responsible for the TLD.
Set authoritative DNS
Nameserver delegation identifies where the domain's DNS records are managed.
Connect services
Add records for the website, mail provider, verification and any subdomains.
Domain name, website and hosting are separate
They are often bought together, but each can be changed independently.
| Thing | What it is | Example |
|---|---|---|
| Domain name | The readable name registered in DNS | example.com |
| Website | The pages, media and application people use | Home, products, checkout |
| Web hosting | The infrastructure serving those files or responses | A server or cloud platform |
| URL | A complete address for one resource | https://example.com/about |
Before you register a domain
- Say the complete name aloud and ask someone else to spell it.
- Check the renewal price, transfer rules and any eligibility restrictions.
- Search for trademark, company-name and close competitor conflicts.
- Confirm the matching email address will be clear and professional.
- Keep registrar login, recovery and renewal details under your control.
- Use auto-renew and a payment method that will remain current.
Common questions
Do I own a domain name forever?
No. You hold renewable registration rights for a term. If the registration expires and passes through its recovery stages, somebody else may eventually register it.
Can one domain point to several services?
Yes. Different DNS records and subdomains can connect web, email, verification, APIs and other services under one domain.
Is a domain name the same as an IP address?
No. The domain is a readable name. DNS can associate it with one or more IP addresses, and those addresses may change while the name stays the same.
Can I move a domain to another provider?
Usually. A registrar transfer moves registration management; changing nameservers or DNS records moves service routing. They are related but separate operations.
