Domain, Hosting & Email

DNS (Domain Name System) translates human-friendly domain names into the addresses and records systems need to reach websites, email, and services.

SPF, DKIM, and DMARC are email authentication standards that help receiving servers detect spoofing and decide what to do with unauthenticated mail.

SSL/TLS encrypts traffic between browsers and servers, enabling HTTPS. It protects data in transit and helps users verify they reached the intended site.

Shared hosting pools server resources among many sites; VPS provides dedicated slices of compute and control. Choose based on traffic, apps, and ops maturity.
