- Introduction
Domain & Hosting Connection is the process of linking a registered domain name (example.com) to a web hosting server so that users can access your website, emails, and related services online. This connection is achieved through DNS (Domain Name System) configuration.
- Key Components Involved
- Domain Registrar: Where the domain is purchased (e.g., GoDaddy, Namecheap)
- Web Hosting Provider: Where website files are stored (Shared, VPS, Cloud, Dedicated)
- DNS Records: Instructions that tell the internet where your domain should point
- Nameservers: Special servers that manage DNS records for the domain
- Methods to Connect Domain to Hosting
Using Nameservers (Recommended)
- Hosting provider gives nameservers (e.g., ns1.host.com, ns2.host.com)
- Update nameservers in the domain registrar panel
- DNS management is fully handled by the hosting provider
- Use case: Blogs, personal sites, small businesses
Pros: Simple, less error-prone | Cons: DNS control stays with hosting provider

- Temporary data storage

| Record Type |
Purpose |
Example |
|---|---|---|
|
A Record |
Points domain to server IP |
example.com → 192.168.1.1 |
|
CNAME |
Alias for another domain |
www → example.com |
|
MX Record |
Email routing |
mail.example.com |
|
TXT Record |
Verification & security |
SPF, DKIM, DMARC |
|
NS Record |
Nameserver control |
ns1.host.com |
- Step-by-Step Domain to Hosting Connection
- Purchase domain from a registrar
- Buy hosting and note server IP / nameservers
- Login to domain control panel
- Update Nameservers or DNS Records
- Save changes
- Wait for DNS propagation (5 minutes to 24 hours)
- Verify website loading successfully
- Email Management with Domain
- Create professional email addresses (info@domain.com)
- Configure MX records
- Add SPF, DKIM, DMARC for email security
- Connect with email services (Google Workspace, Zoho Mail)
- Creating Subdomains
- Subdomains are child domains of the main domain.
Examples:
- blog.example.com
- shop.example.com
- admin.example.com
Steps:
- Open DNS Manager
- Add A record or CNAME
- Assign directory or server IP
- Save and test
