Domain Name

A domain name is a human-readable internet name used to identify resources such as websites, email services, and applications.

A domain name is a human-readable name used to identify an internet resource, such as a website or email service.

Examples include:

  • mannyroy.com
  • canada.ca
  • mozilla.org

A domain provides a stable name that can be connected to different technical infrastructure through DNS.

ICANN explains that domain names provide a text-based alternative to addressing internet resources directly by IP address. ICANN's overview of domain names

Domain Name vs. URL

A domain name is only one part of a URL.

For example:

https://mannyroy.com/resources/glossary/

contains:

Protocol https://

Domain name mannyroy.com

Path /resources/glossary/

Your URL Structure term describes how complete website URLs are organized.

Domain Structure

Domain names are hierarchical.

Consider:

blog.example.ca

Here:

.ca → Top-Level Domain

example.ca → registered domain

blog.example.ca → Subdomain

ICANN describes domain names as hierarchical sequences of labels separated by dots.

Domain Name vs. Website

A domain name is not the website itself.

The same domain can be pointed to different hosting infrastructure without changing the address people use.

Likewise, purchasing a domain does not automatically create a website.

The domain still needs DNS configuration and somewhere for the site to be hosted.

Why It Matters

A domain name becomes an important organizational asset.

It may support:

  • Website URLs
  • Email addresses
  • Subdomains
  • APIs
  • Booking systems
  • Customer portals
  • Redirects
  • Verification records

Losing control of the domain can therefore affect much more than the homepage.

Common Problems

Common problems include:

  • Domain registered under a contractor's account
  • Renewal notices sent to former staff
  • Several similar domains with unclear purpose
  • Registration contact information outdated
  • Domain and hosting ownership confused
  • Important services depending on forgotten subdomains

How to Improve

Keep domain ownership centralized and documented.

Make sure the organization controls:

  • Registrar account
  • Recovery email
  • Multi-factor authentication
  • Renewal billing
  • Registrant information

Then document what services depend on the domain.
