How DNS Names Work: Example with chat.811tech.ca
When you type a web address like chat.811tech.ca into your browser, you’re using the Domain Name System (DNS) to find the right server. Let’s break down what that name means and how it works.
Understanding the Name
.ca→ This is the top-level domain (TLD) for Canada.811tech.ca→ This is the domain name registered under.ca.chat.811tech.ca→ This is a subdomain of811tech.ca, often used to point to a specific service (like a chat server).
So, DNS treats names like a tree, with .ca at the top, 811tech.ca below it, and chat.811tech.ca one step further down.
Who Needs a DNS Server?
A common question is: Does 811tech need to run its own DNS servers?
- The answer: Not necessarily.
- When you register
811tech.ca, you choose which DNS servers hold the records for your domain. - These DNS servers can be provided by:
- Your domain registrar,
- Your web hosting provider, or
- Your own servers (if you want full control).
Adding Subdomains Like chat.811tech.ca
If your hosting provider is managing DNS for 811tech.ca, you can simply add records for subdomains inside their DNS system. For example:
811tech.ca → 203.0.113.10 (main website)
www.811tech.ca → 203.0.113.10 (alias for main site)
chat.811tech.ca → 203.0.113.45 (chat server)
mail.811tech.ca → 203.0.113.60 (mail server)
This way, one DNS server setup can handle the main domain and all of its subdomains.
The Bottom Line
811tech.cadoesn’t need its own physical DNS server.- The DNS service from the hosting provider or registrar is usually enough.
- Inside that DNS, subdomains like
chat.811tech.cacan be configured to point wherever you want.
👉 In short: The DNS system is flexible — you only need your own DNS server if you want advanced control. Otherwise, your hosting provider can manage it for you.
