Dom - AI Domain Guide

New to domains? I'm Dom, your friendly AI guide to the world of domain names. Whether you're launching your first website or just curious about how the internet works, this guide covers everything you need to know about domains.

What Is a Domain Name, Really?

Think of a domain name as your website's street address on the internet. Just like you need a physical address to receive mail, you need a domain name so people can find your website.

When you type "google.com" into your browser, you're using a domain name. Behind the scenes, that friendly name gets translated into a series of numbers (called an IP address) that computers use to find the right server.

"Domain names exist because remembering 'google.com' is much easier than remembering '172.217.164.142'"

Anatomy of a Domain Name

Let's break down a typical domain name using "blog.example.com" as our example:

blog

Subdomain
Optional prefix that creates sections of your site

example

Domain Name
Your unique identifier on the web

.com

Extension/TLD
Top Level Domain indicating the type or origin

Common Domain Extensions Explained

  • .com - Commercial (most popular and trusted)
  • .org - Organization (often used by nonprofits)
  • .net - Network (originally for internet infrastructure)
  • .edu - Education (restricted to educational institutions)
  • .gov - Government (restricted to government entities)
  • .io - Input/Output (popular with tech companies)
  • .co - Company (alternative to .com)

How Domain Names Actually Work (The Simple Version)

Here's what happens when you visit a website:

  1. You type a domain name in your browser
  2. DNS lookup - Your computer asks "Where is this website?"
  3. IP address found - The DNS system returns the server's location
  4. Connection made - Your browser connects to the correct server
  5. Website loads - The server sends the webpage to your browser

This all happens in milliseconds, completely behind the scenes!

Domain Registrars: Your Gateway to Domain Ownership

You can't actually "own" a domain name forever - you rent it through companies called registrars. Think of registrars as the landlords of the internet.

Popular Domain Registrars

  • GoDaddy - Largest registrar, lots of marketing
  • Namecheap - Popular with developers, good pricing
  • Dynadot - Professional tools, auction marketplace
  • Google Domains - Simple interface, Google integration
  • Cloudflare - Registrar services with security focus

What to Look for in a Registrar

  • Competitive pricing (including renewal rates)
  • Easy domain management tools
  • Good customer support when you need help
  • Additional services like DNS, email, or hosting
  • Domain protection features

DNS: The Internet's Phone Book

DNS (Domain Name System) is what makes domain names work. It's like a massive phone book that translates human-readable names into computer addresses.

Key DNS Record Types

A Record

Points your domain to an IPv4 address (most common)

CNAME

Creates an alias (like www.example.com → example.com)

MX Record

Handles email routing for your domain

TXT Record

Stores text information (often for verification)

  4. Complete registration with your contact information
  5. Configure DNS to point to your website or hosting
  6. Set up email if you want custom email addresses
  7. Enable domain protection features as needed

Domain Costs: What to Expect

Domain pricing varies significantly based on extension and registrar:

Typical Annual Costs

  • .com domains: $10-15/year
  • .org/.net domains: $12-18/year
  • .io domains: $35-60/year
  • .ai domains: $80-200/year
  • Premium domains: $100-10,000+/year

Watch out for: Many registrars offer low first-year pricing but charge much more for renewals. Always check the renewal price!

Domain Management Best Practices

Security and Protection

  • Enable domain lock to prevent unauthorized transfers
  • Use strong passwords for your registrar account
  • Keep contact info updated to receive important notices
  • Enable auto-renewal to avoid accidental expiration
  • Consider privacy protection to hide your personal information

Performance and SEO

  • Use fast DNS providers for quicker website loading
  • Set up proper redirects from www to non-www (or vice versa)
  • Monitor domain expiration dates religiously
  • Consider buying variations of your main domain to protect your brand

Common Domain Mistakes Beginners Make

⚠️ Letting Your Domain Expire

This is the #1 mistake! If your domain expires, you could lose it forever. Set up auto-renewal and keep your payment info current.

⚠️ Choosing the Wrong Registrar

Not all registrars are equal. Research pricing, features, and support quality before committing.

⚠️ Ignoring DNS Configuration

Having a domain is only half the battle - you need to properly configure DNS to make it work with your website and email.

Advanced Domain Concepts (Optional Reading)

Domain Transfers

You can move your domain between registrars if you're unhappy with your current one. The process typically takes 5-7 days and requires:

  • Unlocking your domain
  • Getting an authorization code (EPP code)
  • Initiating transfer at the new registrar
  • Confirming the transfer via email

Premium and Expired Domains

Some domains cost more because they're considered "premium" (short, keyword-rich, or previously owned by successful sites). You can also find good domains in expired domain auctions.
