Configure DNS records, connect hosting, set up SPF, DKIM, DMARC and SSL, secure domains, and troubleshoot failures.
What you'll learn
⚡ Explain how domains, DNS, IP addresses, websites, email, and hosting work together.
⚡ Register, renew, transfer, secure, and recover a domain using a repeatable control checklist.
⚡ Read current RDAP registration data and understand privacy, status codes, lifecycle stages, and transfer restrictions.
⚡ Evaluate domain value using brandability, keywords, history, comparable sales, cost, liquidity, and legal risk.
⚡ Create a safe domain marketplace listing and compare fixed-price, make-offer, auction, broker, and direct-sale options.
⚡ Compare shared, VPS, dedicated, cloud, managed CMS, and reseller hosting for real customer scenarios.
⚡ Configure core DNS records and connect a domain to a hosting or email service in a practice environment.
⚡ Use a WHM-style workflow to design packages, create accounts, assign limits, and manage reseller-hosting responsibilities.
⚡ Compare domain and hosting vendors using support, uptime, security, backup, pricing, escalation, and reputation criteria.
Requirements
❗ A computer with a modern web browser and a stable internet connection.
❗ No programming, server-administration, or prior domain-investing experience is required.
❗ A spreadsheet application is helpful for the included calculators and workbook.
❗ No live domain, hosting purchase, private account, or server login is required for the practice lessons.
❗ Students should expect examples and provider terms to change over time and verify live prices before making decisions.
Description
This course contains the use of artificial intelligence.
Master the practical DNS and domain-management skills needed to connect websites, deliver email, enable SSL, protect domains, and troubleshoot failures. This course is designed for website owners, support staff, junior administrators, freelancers, and hosting professionals who want a clear mental model instead of trial-and-error changes.
You will learn how the DNS hierarchy works, how registrars and authoritative nameservers interact, and how recursive lookups reach an answer. Hands-on lessons cover A, AAAA, CNAME, MX, TXT, NS, CAA, SRV, and common verification records. You will practice reading zones, understanding TTL and propagation, planning nameserver changes, and connecting domains to hosting or third-party services.
Email authentication is taught as a complete system. You will configure and interpret SPF, DKIM, and DMARC, identify alignment problems, and use headers and DNS evidence to investigate delivery failures. SSL modules explain certificate validation, HTTPS, renewals, mixed content, and the difference between DNS problems and certificate problems.
Security lessons cover registrar locks, account protection, DNSSEC concepts, least-privilege access, change documentation, rollback plans, and safe domain transfers. Troubleshooting labs include missing records, duplicate SPF policies, broken CNAME chains, incorrect MX priorities, stale caches, nameserver mismatches, and failed validation.
Your capstone is a controlled DNS cutover: audit the current zone, build the replacement, lower TTL safely, migrate website and email records, validate SSL and authentication, monitor the change, and prepare a rollback report. Downloadable checklists, worksheets, command references, and quizzes support the work.
By the end, you will be able to make DNS changes methodically, verify the real result, and explain what happened in language a client or teammate can understand.
