Remember when I registered my first website? Back in 2007, I spent hours debating between .com and .net like it was life-or-death. Fast forward to today, choosing a domain feels like walking into an ice cream shop with 1,500 flavors - exciting but downright overwhelming. That's why I've compiled this list of all domain extensions, because frankly, most registry websites make this way harder than it needs to be.
What Are Domain Extensions Anyway?
Let's cut through the jargon. Domain extensions (or TLDs - Top-Level Domains) are those letters after the dot in web addresses. Think .com in google.com. They're not just technical fluff - they tell visitors what to expect before they even click. When I launched my photography site, using .photos instead of .com cut my bounce rate in half. People instantly "got" what I offered.
The Evolution Nobody Talks About
Back in 1985, you had exactly seven choices. Seriously! Only .com, .edu, .gov, .mil, .net, .org, and .int existed. Today? We're swimming in over 1,500 options thanks to ICANN's expansion. Some criticize this as money-grabbing (and okay, maybe some extensions like .pizza are questionable), but having .tech for startups or .io for developers? That's legitimately useful.
The Complete Domain Extension Breakdown
Let's get practical. You don't need to memorize every single one, but knowing categories helps tremendously:
The Classics (gTLDs)
These are the OGs. Most recognizable, but surprisingly not always the best choice anymore:
| Extension | Original Purpose | Current Reality | Registration Cost |
|---|---|---|---|
| .com | Commercial entities | Default for everything (good luck finding your name!) | $10-$15/year |
| .org | Non-profits | Still preferred for charities, open-source projects | $12-$20/year |
| .net | Network infra | Tech companies, backup when .com unavailable | $12-$18/year |
| .info | Information resources | Underused, often available when others aren't | $5-$25/year |
Personal opinion? .net feels dated unless you're actually in networking. I registered one in 2015 and still regret it.
Pro Tip: If .com is taken, check if the owner is actively using it. I once got a premium domain for $500 instead of $5,000 just because the squatter hadn't renewed their SSL cert - dead giveaway they'd sell cheap.
Country Codes (ccTLDs)
These two-letter extensions like .us or .uk have secret powers beyond geography:
| Extension | Country | Creative Uses | Restrictions |
|---|---|---|---|
| .io | British Indian Ocean | Tech/startup darling (Input/Output) | None |
| .co | Colombia | Popular .com alternative | None |
| .tv | Tuvalu | Streamers, video creators | None |
| .me | Montenegro | Portfolios, personal brands | None |
Fun fact: The tiny island nation of Tuvalu earns 10% of its GDP from .tv sales. Mind-blowing, right?
Niche Extensions (nTLDs)
This is where things get interesting... or ridiculous. After managing domains for 40+ clients, here's what actually works:
| Category | Extensions | Best For | Effectiveness |
|---|---|---|---|
| Creative | .design .art .photo .studio | Portfolios, freelancers | ⭐⭐⭐⭐⭐ |
| Tech | .app .dev .cloud .ai | SaaS, developers | ⭐⭐⭐⭐ |
| Business | .inc .co .company | Startups, corporations | ⭐⭐⭐ |
| Gimmicky | .pizza .beer .ninja | Novelty ONLY (avoid for serious biz) | ⭐ |
I tried .guru for a consulting site once. Big mistake - clients kept typing .com anyway. Stick to extensions people can easily remember.
How to Actually Use This List of All Domain Extensions
Finding your perfect domain isn't about scrolling through every single option. Follow this battle-tested process:
Step 1: Define Core Keywords My bakery client wanted "crumb" in their name. We got crumb.bakery instead of crumblybakerychicago.com - cleaner and instantly recognizable.
Step 2: Map Extensions to Goals Selling products? .store beats .com for e-commerce clarity. Local service? .nyc or .london outperform generics.
Step 3: Verify Availability LIKE THIS Don't just check your dream name - search variations:
yourbrand[extension] → yourbrandapparel[extension] → theyourbrand[extension]
Step 4: Check Hidden Costs Got excited about .luxe? Premium domains can cost thousands annually. Always read renewal fees before falling in love.
Domain Crisis Story: A client didn't verify trademark conflicts on their .io domain. Six months later, legal fees cost more than their entire web build. Always search USPTO.gov first!
Critical Registration Details Everyone Misses
After helping recover hijacked domains, trust me - these matter:
Provider Red Flags
Free WHOIS privacy actually costs $20/year at renewal? Yep, seen it. Watch for:
- Cheap first-year → expensive renewals
- No free DNS management (run if they charge for this)
- Transfer locks requiring phone calls to disable
Security Must-Do's
Enable these immediately after registration:
- Registry Lock (prevents unauthorized transfers)
- DNSSEC (stops DNS poisoning attacks)
- Two-factor authentication (obvious but often skipped)
Lost a client's .ai domain to phishing last year. Took 47 days to recover through ICANN arbitration. Don't be me.
FAQs: Real Questions from Actual Website Owners
Q: Is there actually a complete list of all domain extensions?
A: Technically no - new ones launch monthly. The most current official registry is IANA's root zone database. But for practical purposes, our curated lists cover 99% of usable options.
Q: Do weird extensions hurt SEO?
A: Google says no, but indirectly yes. When my .space site had 40% more typos than our .com version, bounce rates skyrocketed. Stick to recognizable TLDs unless you have strong branding.
Q: Why does .com cost $15 when .xyz costs $1?
A: Basic economics - high demand (.com) vs new TLDs trying to gain adoption. But beware: super cheap extensions attract spammers. We've seen .icu domains get blocked by corporate firewalls.
Q: Can I register .bank or .pharma?
A: Only if you're actually a bank or pharmaceutical company with verified credentials. These are "restricted TLDs" with strict validation processes.
Unexpected Ways Extensions Impact Your Business
Beyond just web addresses:
Email Perception Matters
[email protected] looks infinitely more professional than [email protected]. For service businesses, matching extensions to industries builds instant credibility.
Local SEO Bonuses
Google treats geo-specific TLDs like .london as a ranking signal for local searches. For brick-and-mortars, pairing with GBP listings creates unstoppable synergy.
Investment Potential
While mostly hype, some extensions have appreciated:
2018: crypto domains (.crypto, .blockchain)
2021: AI-related domains (.ai, .ml)
2023: Climate tech (.earth, .eco)
But unless you're a domain investor, focus on utility over speculation.
2021: AI-related domains (.ai, .ml)
2023: Climate tech (.earth, .eco)
Future-Proofing Your Domain Strategy
Based on ICANN's pipeline:
What's Coming Next
- Brand TLDs (like .apple or .bmw)
- Regional city extensions (.paris, .berlin)
- Industry-specific (.med, .law)
My Registration Checklist
Before hitting "purchase":
- Search trademark databases (global!)
- Verify registry reputation (avoid fly-by-night operators)
- Setup auto-renew + payment backup method
- Lock domain immediately after registration
