What is a Domain Name?

A domain name is a unique name that helps identify a website like “google.com” or “wordpress.org”. It’s the human-friendly address entered into browsers and used in marketing.

Without them, you’d have to promote and type complex IP addresses like “192.168.1.1”. Not very brandable or memorable!

A domain name provides three core functions:

1. Identifies your site with a unique address
2. Makes it easy to market and remember
3. Translates numeric IPs to direct browsers

It’s the custom web address helping visitors find and access your content online.

So before launching any website or blog, the first step is registering your own domain.

But if domains help route to my site’s location, then how do they actually work?

How Domains Map to IP Addresses

To understand what goes on behind the scenes when someone enters your domain, you need to know domains are mapped to IP addresses.

An IP address is a unique set of numbers identifying each device connected to the web (like 192.168.1.1).

This numeric address is assigned by your internet service provider and points to the actual location of your hosting server storing site files.

A domain name works by…

1. Getting registered with a registrar and connected with hosting DNS settings
2. Getting paired with your server’s unique IP
3. Helping DNS translate the domain into that IP

This enables requests to route to the right destination when visitors enter your URL.

So while the IP targets the exact server location, the domain offers memorable branding that indirects people there. Together they facilitate access to your content.

Breaking Down the Parts of a Domain

All domain names have three parts working together:

1. Top-level domain name (TLD)
2. Second-level domain
3. Subdomains

Combined, they form the fully qualified domain name directing traffic. Let’s examine what each part does.

Top-Level Domain Name (TLD)

The top-level domain is the suffix appearing after your domain like .com or .net. There are over 1000+ TLD extensions today from:

• .biz
• .info
• .co
• .me

But the most common TLDs are:

• .com – Commercial sites
• .org – Organizations
• .net – Networks and infrastructure
• .edu – Educational institutions

The TLD signifies the site’s industry or geography. It also categorizes the extension authority overseeing management for TLDs.

For most sites, .com stands as best practice to convey credibility.

Second-Level Domain Name

The second-level domain appears before the TLD and is the main website URL seen in marketing. Using mysite.com:

• Second-level: mysite

This identifies the brand and domain. A brandable, keyword-rich domain builds name recognition and drives traffic from search.

Visitors remember it, while Google favors domains aligning to page content.

Subdomains

Subdomains include terms appearing before the second-level domain, like:

• mail.mysite.com
• blog.mysite.com

Subdomains logically segment websites into categories or properties. They also help manage large sites.

So in summary, the fully qualified domain combines:

Subdomain + Second-level domain + TLD

Understanding domain anatomy helps when getting your custom name.

How to Check Domain Name Availability

Before going further, let’s cover how to see if your preferred domain is available to register.

With so many sites today, chances are the .com exact match of your first choice is taken.

To check, use domain name generators and the search bars on registrar sites:

• GoDaddy Domain Search
• Namecheap Domain Checker

If it comes back as taken, try different variations by adding/removing words, hyphens, abbreviations, etc. until you find an alternative available .com matching your brand.

Pro-Tip

Even if your perfect .com match is registered, consider contacting the current owner to ask if they are willing to sell. Offer a fair price if interested in acquiring the domain outright.

If you secure an available .com domain reflecting your company, the next step is registration.

So once you locate an available .com reflecting your company, how do you actually register it?

How to Register Your Domain Name

Domain registrars handle the registration, configuration and management of internet domains.

Well-known registrars include:

• GoDaddy – World’s largest domain registrar
• Namecheap – Budget-friendly registrar
• Bluehost – Domains + hosting bundles

When you buy a domain, you’re entering a yearly contract with one of these registrars covering rights, DNS services, privacy protection, etc.

The domain registration steps are:

1. Find available domain – Use registrar’s domain search to check availability.
2. Pick a registrar – Decide where you want to register and manage domains.
3. Purchase & register domain – Buy and configure domain/owner data via registrar.
4. Set up automatic renewal – Domains expire annually. Enable auto-renew to prevent losing ownership.
5. Connect domain to web hosting – Point domain to hosting nameservers to direct visitors.

Registration costs average $15 per year. It’s affordable and provides access to built-in registrar tools.

Now with a registered domain in hand, how do you actually get it functioning for your website?

This brings us to…

How DNS Directs Traffic to Your Site

Previously, we covered how domains must translate IP addresses to route requests intended for your server. But how does that actually happen?

The magic ingredient is the DNS system.

DNS stands for Domain Name System. It’s a network of servers powering domain name functionality.

When people enter your custom domain, behind the scenes…

1. Their computer asks a DNS resolver to translate the domain into an IP
2. The DNS server queries the domain’s registrar for the site’s IP
3. The registrar returns the hosting IP tied to that domain
4. DNS caches and routes requests containing the IP to your host server

This enables all web, email and other traffic to route properly using assigned IP addresses.

In other words, DNS makes domains work via continual IP translation.

That’s why connecting domains to web hosting IP addresses matters so much – it points DNS to your content for visitors globally.

How to Point a Domain to Web Hosting

Pointing your domain to web hosting IP completes the connection enabling DNS to redirect traffic automatically.

You must configure two things to make this work:

A) Nameservers

Nameservers act like phonebooks in DNS. They route queries to the correct destination IPs.

To set them up:

• Login to domain registrar account
• Find DNS settings
• Enter web host nameservers

B) DNS Records

DNS records translate domain/IP pairs directing requests.

Configure them via:

• Web host DNS zone editor
• Add A record with host IP
• Assign domain

Consult your registrar and host for specifics. But this domains tutorial covers the key steps to get yours pointing visitors properly.

Choosing a Good Domain Name: 5 Key Tips

If domains play such a crucial role, how do beginners even select a good one suited for professional use?

Keep these proven tips in mind:

Keep it Short

Shorter domains are much easier to remember and type. Stick to:

• 1-3 words
• Under 20 characters
• 2-3 syllables

Maintaining brevity makes your brand much more usable.

Make it Brandable

Domains become part of your brand. Brainstorm names evoking your company identity or offerings – like Lynda.com.

Descriptiveness helps visitors understand your site purpose intuitively while amplifying brand recall.

Be Keyword-Relevant

Domains containing highly relevant keywords can improve site visibility and clicks from search engines. Just don’t overdo it.

Aim for 1-2 precise, prominent terms users would search around your topic. Avoid excessive broad keyword stuffing as that appears spammy.

Secure the .com Version

Owning the .com exact match of your domain ensures brand consistency everywhere.

If already taken, try .net or .co variations. But also consider acquiring the .com and redirecting it to your primary domain.

Test Pronounceability

Always test how the domain sounds when said aloud. Complex names with odd characters or number sequences end up confusing audiences unable to pronounce or remember them.

If it’s difficult to convey verbally, rework your domain.

Sticking to short, brand-focused names with pronunciation ease makes your domain very user and marketing friendly.
