Domain names, DNS, and business email: basics for NZ website owners

Short answer: your domain is an asset. Keep registration in your control, understand DNS enough to launch confidently, and separate email decisions from “whatever the web person used”.

Many SMEs only think about domains once a decade—then a renewal, transfer, or DNS change becomes urgent. This guide explains the moving parts without turning you into a network engineer.

What is a domain registrar—and why does ownership matter?

A registrar records who controls the domain. You want the business (or director) to hold the account credentials, not an employee’s personal email that might disappear. Losing registrar access is one of the most painful website emergencies.

What is DNS, in one paragraph?

DNS translates your domain into instructions: where the website is hosted, where email is delivered, and sometimes verification records for security tools. A small DNS mistake can take a site offline or break email—changes should be planned, not rushed.

How should you handle business email?

Many NZ businesses use Microsoft 365 or Google Workspace for reliability and support. You can keep email separate from website hosting—often a good idea—provided DNS is configured correctly. If you rely on “free email forwarding”, understand limitations and deliverability risks.

What are common pitfalls?

• Letting a developer register the domain in their own account without transfer documentation.
• Changing nameservers blindly and accidentally breaking email.
• Ignoring renewal reminders until the domain enters redemption.
• Using personal Gmail for critical registrar 2FA recovery.
