DNS records every Irish business should understand

DNS is the phonebook of the internet. When someone types your domain, DNS decides which server answers — and which mail system receives messages.

The records you will actually touch

• A / AAAA — point the domain at a server IP.
• CNAME — alias one name to another (often www).
• MX — mail routing.
• TXT — SPF, domain verification, sometimes DKIM.

Change one thing at a time, wait for TTL, and keep a screenshot of the last known-good zone. Host Cloud support can review a zone file with you before a go-live.

Details that usually get skipped

Document ownership of the domain registrar login, the hosting panel, and the DNS editor. Many outages last longer because the only person with access is on leave. Keep a short internal runbook: where DNS lives, where backups live, who approves restores.

Measure before you guess

Before changing plans, capture current response times and error rates. Upgrades should answer a measured problem — CPU saturation, slow TTFB, mail deferrals — not a vague feeling that “the site is heavy.”

What this means day to day

Good infrastructure decisions show up in ordinary moments: a page that opens on a phone in traffic, an invoice that lands in the inbox instead of spam, a restore that takes minutes instead of an afternoon of guesswork. That is the standard we aim for at Host Cloud.

How we work with you

Phone support is available Monday to Friday, 9:00–17:00. Email and live chat run 24/7. When you open a ticket, send the domain name, what changed recently, and a screenshot or error text — it cuts diagnosis time sharply.

Next steps

If you want a second pair of eyes on your current setup, contact Host Cloud with your domain and goals. We will tell you what is already fine, what should move, and what can wait.
