DNS Domain Setup (Optional)

Some advanced HackerOps labs require a real domain name for DNS automation, phishing simulations, and web application deployments. While optional, having a domain enhances the learning experience.

Info

Optional Requirement: Domain names are only needed for specific advanced labs. You can skip this initially and purchase a domain when you reach those labs.

Why You Might Need a Domain

Domains are used in labs for:

  • DNS automation with Terraform and Ansible
  • Web application hosting and SSL certificate management
  • Phishing simulation exercises (ethical hacking)
  • Real-world scenarios that require legitimate DNS records

Cost Considerations

  • Budget-friendly options: $10-15 per year for most TLDs
  • One-time cost: Use for the entire course duration
  • Learning investment: Provides hands-on experience with real DNS

Domain Options

  1. Already Have a Domain - Use a subdomain like hackerops.yourdomain.com to avoid conflicts with existing services

  2. Need to Purchase - Buy an inexpensive domain specifically for learning purposes

  3. Skip for Now - Continue with other labs and purchase when needed for advanced exercises

Recommended Domain Registrars

Porkbun (Recommended)

  • Why: No hidden fees, great prices, simple interface
  • Cost: $8-12/year for most domains
  • Link: porkbun.com

Alternative Options

  • Namecheap: User-friendly with good pricing
  • Google Domains: Simple integration with Google services
  • Cloudflare Registrar: Great for advanced DNS features

Domain Selection Tips

Choose a domain that:

  • Is inexpensive (avoid premium TLDs)
  • You’re comfortable using for learning/testing
  • Doesn’t conflict with existing brands
  • Is easy to remember and type

Good TLD options:

  • .com - Most common and reliable
  • .org - Often cheaper than .com
  • .net - Good alternative option
  • .xyz - Very affordable option

What NOT to Buy

Caution

Avoid: Premium domains, expensive TLDs (.io, .dev), or domains you plan to use for production websites.

  • Don’t spend more than $15/year
  • Avoid domains with renewal price increases
  • Skip privacy protection for learning domains
  • Don’t buy multiple years upfront

DNS Management

Once you have a domain:

  1. Keep default nameservers initially
  2. Note your registrar’s DNS management interface
  3. Test basic DNS records (A, CNAME, TXT)
  4. Save domain credentials securely

Lab Integration

In the labs, you’ll learn to:

  • Automate DNS record creation with Terraform
  • Configure subdomains for different services
  • Set up SSL certificates with Let’s Encrypt
  • Manage DNS for web applications

Alternative: Free Options

If you prefer not to purchase a domain:

  • Use provided lab domains when available
  • Focus on local development with /etc/hosts modifications
  • Skip domain-specific labs and focus on other exercises
  • Return later when ready to purchase

Next Steps

Domain setup completed:

  1. Complete your environment - Ensure all tools are ready
  2. Start basic labs - Build foundational skills
  3. Return for DNS labs - Use your domain in advanced exercises

Tip

Pro Tip: Many students find domain-based labs among the most valuable for real-world skills. The small investment often pays off in practical experience.
