What Is a Subdomain?
A subdomain is an extension of your main domain that can host separate content but is still logically tied to the primary website.
Example:
blog.yourdomain.com
support.yourdomain.com
store.yourdomain.com
How It Works
- Created under your main domain
- Stored in its own directory (e.g., /public_html/blog)
- Can run its own CMS or application
Best Used For
- Blogs or knowledgebase sections
- Development or staging sites
- Department-specific sections (e.g., support portal)
What Is a Domain Alias?
A domain alias (also called Parked Domain) is an additional domain name that points to exactly the same website as your main domain.
Example:
yourdomain.com
yourdomain.net
yourdomain.my
All show the same content.
How It Works
- No new folder is created
- No separate website exists
- Visitors see identical content regardless of which domain they use
Best Used For
- Protecting your brand from competitors
- Owning multiple extensions of the same name
- Redirecting alternative spellings
What Is an Addon Domain?
An addon domain allows you to host a completely separate website within the same hosting account.
Example:
You can host:
- companyA.com
- companyB.com
- projectC.com
All inside one hosting plan, each with independent content.
How It Works
- Each addon domain has its own directory (e.g., /public_html/companyB)
- Functions like a standalone hosting account
- Has its own email accounts, databases, and applications
Best Used For
- Hosting multiple businesses
- Running unrelated projects under one plan
