Domain Management

Domain Management - DNS, SSL and Security.

Domain management is effectively the foundation of a company's online presence - and it's not just about buying a name. It's a whole set of technology decisions that can determine the security, performance and perception of your brand. Sometimes the difference between a correct and incorrect configuration is so subtle that it can seem trivial, yet costly.

Key areas include DNS settings and basic records (A, CNAME, MX, TXT), which is how a domain "behaves" in practice. You'll learn how to properly set up 301 redirects, manage subdomains and implement SSL certificates (such as Let's Encrypt or wildcard), as well as when it's a good idea to redirect mail to Google Workspace or another provider. These are concrete, practical tips, not poster theory.

Domain security is a separate chapter - protection against unauthorized transfers, Domain Lock, and valid SPF, DKIM and DMARC records for mail. This may seem like overkill, but in practice these mechanisms significantly reduce the risk of impersonation. We will also suggest what monitoring tools are worth using (such as DNS monitoring or UptimeRobot) and how to detect problems quickly.

When you have several or a dozen domains, you need a systematic approach: central portfolio management, automation of renewals and integration with hosting and registrars (e.g. Namecheap, GoDaddy). From my own experience, I can add that good tools and procedures easily prevent costly configuration errors.
