Domains and DNS

Domains and DNS are the quiet infrastructure behind a working website and dependable email. This section explains how domain records connect browsers, hosting providers, email services, verification tools, and other systems—without treating every change as an all-or-nothing migration.

Use these guides before moving a website, changing nameservers, adding a verification record, or separating web hosting from email hosting. You will learn how to inventory existing records, identify which provider controls each service, preserve MX records, lower risk through one-change-at-a-time testing, and document a known-good configuration before touching live DNS.

These articles also answer the everyday questions people use when something feels wrong: “Why did my email stop after I moved my website?”, “Can my website and email use different companies?”, and “Will changing DNS take my site offline?” Clear terminology matters, but so does translating technical records into the service each one protects.
